Bryan Vaniman — Senior Vice President, Investor Relations
Good afternoon, everyone, and thank you for joining us for Twilio’s fourth quarter 2024 earnings conference call. Joining me today are Khozema Shipchandler, chief executive officer; and Aidan Viggiano, chief financial officer. As a reminder, we will disclose non-GAAP financial measures on this call. Definitions and reconciliations between our GAAP and non-GAAP results can be found in our earnings release and our earnings presentation posted on our IR website at investors.twilio.com.
We will also make forward-looking statements on this call, including statements about our future outlook and goals. Such statements are subject to known and unknown risks and uncertainties that could cause actual results to differ materially from those described. Many of those risks and uncertainties are described in our SEC filings including our most recent Form 10-Q and our forthcoming Form 10-K. Forward-looking statements represent our beliefs and assumptions only as of the date such statements are made.
We disclaim any obligation to update any forward-looking statements except as required by law. And with that, I’ll hand it over to Khozema, who will discuss our Q4 and 2024 results, and we’ll then open the call for Q&A.
Khozema Z. Shipchandler — Chief Executive Officer
Thank you, Bryan. Good afternoon, everyone, and thank you for joining us today. Twilio had a terrific Q4, reaching $1.195 billion in revenue, an 11% increase year over year, and our second consecutive quarter of double-digit growth. Q4 also marked an important milestone for Twilio as it’s the first time we’ve delivered quarterly GAAP operating profitability in the company’s history, well ahead of our initial target.
For the full year, we generated $4.458 billion in revenue, representing 9% organic growth year over year. Over the past two years, we’ve dedicated ourselves to transforming Twilio’s business from one primarily focused on growth to one that balances innovation, growth, and profitability. Our results demonstrate the success of those efforts. Not only have we recently accelerated revenue growth, but we’ve also significantly boosted our non-GAAP profitability while meaningfully accelerating our path to GAAP profitability plus reducing our net burn rate and outstanding share count.
And we’ve increased annual free cash flow by nearly $1 billion since 2022. All of this illustrates our commitment to operating the company with more discipline, rigor, and focus. And while there’s more work to be done, the results speak for themselves. At our Investor Day a few weeks ago, you got a chance to hear about the new Twilio, including our product strategy, growth levers, and financial framework that we have in place to win a much larger addressable market.
As marketing, sales, and customer support converge into customer experience as a service, we strongly believe that Twilio’s leading communications platform plus contextual data powered by Segment and our innovations with AI position us to win in this massive market and reinforce our vision that every digital interaction we power between brands and consumers is nothing short of amazing. While we provided a lot of details during our Investor Day, today I wanted to take the opportunity to reinforce a few of the key takeaways, while also sharing some of the highlights from Q4. On the innovation front, in 2024, we launched 251 products, enhancements, and services. These innovations align to our strategy of building a trusted, simple, and smart platform that enables brands to drive more secure, relevant, and personalized interactions with their customers.
Throughout the quarter, we continued to invest in our core capabilities to drive even greater customer value. During Cyber Week, Twilio powered more than 5 billion messages, delivered more than 65 billion emails, and supported 678 million calls, all while delivering 100% uptime. The confidence our customers have in Twilio is stronger than ever and critical periods like Cyber Week proved to our customers that Twilio has the trusted, simple, and smart platform that they need. During the fourth quarter, we expanded our trusted channels to meet our customers’ evolving needs by adding new capabilities to support existing channels, including RCS and WhatsApp.
For RCS, we also recently announced that rich content cards, media, and rich card carousels are now available and supported by our Content Template Builder that helps streamline development. RCS is proving a valuable expansion vehicle for existing messaging customers. Customers like MarketBeat are able to benefit from Twilio’s streamlined approach to development on a single messaging API and our universal template management system. It’s also clear that Twilio continues to be at the center of the AI value chain as we already have 90% of the Forbes 50 AI start-ups building on Twilio.
We continued to drive ROI with our AI-enabled products, benefited from emerging AI companies that chose Twilio as an essential component for their customer engagement layer, and partnered with key AI players in the ecosystem like AWS, Databricks, Google Cloud, OpenAI, and Snowflake. In Q4, ConversationRelay, which helps simplify the process of building robust AI voice agents, went into public beta. While it’s still early, we believe that AI will drive a renaissance in voice and everyone from enterprises to start-ups will begin orchestrating new voice experiences that are two-way and personalized. On the segment front, the AI innovations that went live throughout 2024 are beginning to generate tangible results for our customers.
As an example, with predicted audiences, one company realized a 70% improvement in audience accuracy. And in Q4, found an average of four weeks of data science time saved by giving marketers the ability to predict behavior. Emerging AI start-ups are continuing to build on Twilio. In fact, more than 9,000 companies building in the AI space utilized Twilio services in 2024.
Paradox.ai, one of Twilio’s AI searchlight winners is using conversational AI for recruiting and leverages their AI assistant, Olivia, to help with frontline recruitment. Starting as a self-serve customer in 2017, they reached unicorn status in under five years. And today, Twilio powers over 150 million messages a month on their behalf. But more importantly, with Twilio messaging, they’ve been able to help companies like McDonald’s, Workday and SAP get interviews scheduled in minutes, versus the manual process that used to take anywhere from five to seven days.
And finally, we’re continuing to partner with established AI companies like OpenAI. During the quarter, we helped OpenAI launch calls and WhatsApp messaging through their Twilio-powered number 1-800-CHATGPT, which has seen incredible volume since launch. Our innovation strategy and execution continues to pay off as we were named a leader in multiple analyst reports. During the quarter, IDC named Twilio a leader in its MarketScape worldwide customer data platforms focused on B2C users.
And Omdia also named Twilio a leader in two of its reports: the Omdia Universe Customer Engagement Platforms and the Omdia Universe Customer Data Platforms. With respect to distribution, we continued to focus on our key growth levers: self-serve, cross-sell, international expansion, and our partner ecosystem, while also optimizing for scale and efficiency. In Q4, our go-to-market team continued to deliver improved execution as evidenced by strong large deal activity during the quarter. On the communications side, we closed 78 deals worth $500,000 or more, up 47% year over year.
And in Q4, we closed our largest Segment deal ever with one of the world’s largest financial services companies. Within self-serve, we saw a continued acceleration in sign-ups, upgrades, and revenue growth, a testament to the improvements we’ve delivered in our self-serve experience over the course of 2024. Cross-sell and upsell continues to be a massive growth opportunity. During the quarter, we had terrific wins, including one with a long-standing Twilio voice customer that’s a top health system in the U.S., which operates 33 hospitals.
The customer adopted Twilio’s RCS Messaging, Branded Calling, and Engagement Suite in order to increase call adoption, establish a stronger brand presence, and increase messaging deliverability and engagement. Additionally, we also signed a deal with a leading web hosting provider. The company has been a longtime Twilio Messaging customer and expanded their use to include Twilio’s Conversations API to power two-way SMS and voice channels. With Twilio, the company has integrated the product into their own proprietary unified inbox, giving customers the ability to manage their business communications needs on their smartphone and simplify the communication with their own customers.
International expansion and partner distribution continue to help us unlock an underpenetrated addressable market. As an example, during the quarter, Twilio expanded its relationship with Klaviyo with several SMS deals in European markets. Finally, we are driving our go-to-market strategy more efficiently by leveraging AI and automation, which is built upon Twilio’s own technology. In presales, we’re using data to lead the identification process, which has shortened sales cycles.
Additionally, today, 80% of our new inbound leads are being handled by AI, which has led to a faster sign-up and upgrade process for prospects due to faster responses, multilingual support, and depth of knowledge. Post sales, our help center assistants have garnered a 75% ticket deflection rate when AI is engaged. I’m proud of how our discipline, rigor, and focus has helped position the company well for the years ahead as we drive strategic customer-centric growth with innovation at the core. In many respects, 2024 was about rebuilding the foundation.
2025 is the year we’ll stay focused on executing against our ambitious innovation road map to unlock the power of communications, contextual data, and AI. And as we unlock it, every consumer that interacts with the 325,000-plus active customer accounts that we power will benefit. Our strategy is clear, our execution is focused, and our impact is real. I’m incredibly proud to see the hard work paying off as we enter this next phase of growth and create more value for our shareholders in the years ahead.
And with that, I’ll turn it over to Aidan.
Aidan Viggiano — Chief Financial Officer
Thank you, Khozema, and good afternoon, everyone. Twilio finished the year with a strong Q4, delivering our second consecutive quarter of double-digit revenue growth and our first-ever quarter of GAAP operating profitability. For Q4, we generated record revenue of $1.195 billion, which represented 11% year-over-year growth. We also generated record non-GAAP income from operations of $197 million and $93 million in free cash flow.
We came into 2024 committed to driving durable growth, continued margin expansion, and increased free cash flow generation. And I’m pleased with our execution throughout the year. For the full year, we generated revenue of $4.458 billion, representing 9% organic growth. Non-GAAP income from operations of $714 million and free cash flow of $657 million.
We also completed our prior $3 billion share repurchase authorization, returning over $2.3 billion to shareholders in 2024 alone and reducing our outstanding share count by 16% since the start of the year. Revenue in our communications business for the quarter was $1.121 billion, up 12% year over year. Messaging revenue growth accelerated for a second consecutive quarter, while email performance remained strong, driven in part by strong volumes during Cyber Week and the holiday season. Political revenue contributed roughly 60 basis points to our reported revenue growth rate.
This was partially offset by a 40-basis-point headwind associated with sunsetting the software component of our Zipwhip business, which we have now fully lapped. Segment revenue for the quarter was $74 million, down 1% year over year. We were encouraged by the go-to-market execution in the quarter with bookings slightly accelerating year over year, along with over half of new bookings coming from multiyear deals. Our Q4 dollar-based net expansion rate was 106%, representing our best performance since Q1 of 2023 and reflecting the improving growth trends we’ve seen in our communications business over the last several quarters.
Our dollar-based net expansion rate for communications was 108% and the dollar-based net expansion rate for segment was 93%. We delivered record non-GAAP gross profit of $621 million, up 10% year over year. This represented a non-GAAP gross margin of 52%, down 40 basis points year over year and 100 basis points quarter over quarter. The decline in gross margins was driven by expected higher hosting costs during Cyber Week, as we referenced during our Q3 earnings call, along with an increase in revenue mix from messaging.
Non-GAAP gross margin for our communications business unit was 50.6%, down 10 basis points year over year and 110 basis points quarter over quarter. As we referenced on our Q3 earnings call, the sequential decline was driven primarily by higher hosting costs associated with the holiday shopping season as well as higher messaging revenue mix. Non-GAAP gross margin for our segment business unit was 72.3%, down 210 basis points year over year and up 240 basis points quarter over quarter. The sequential improvement was primarily driven by benefits from our segment infrastructure migration project as well as hosting credits in the quarter.
We largely completed this project during the fourth quarter, which we expect will help support segment gross margins as we move into 2025. Q4 non-GAAP income from operations came in modestly ahead of expectations at a record $197 million, up 14% year over year, driven by strong revenue growth and ongoing cost discipline. Our non-GAAP operating margin of 16.5% was up 40 basis points year over year and sequentially. In addition, we generated $14 million in GAAP income from operations, representing Twilio’s first-ever quarter of GAAP operating profitability.
As I referenced at Investor Day last month, in Q4, we incurred $17 million in bad debt expenses related to our customer, Oi, a Brazilian telecom company as a result of a slowdown in their ongoing payment activity. We fully reserved our exposure to Oi’s existing accounts receivables, which reduced operating margin by 140 basis points in the quarter. For the full year 2024, we generated non-GAAP income from operations of $714 million, up 34% year over year, and our non-GAAP operating margin of 16% was up 320 basis points year over year. Non-GAAP income from operations for our communications business was $275 million in the fourth quarter.
For the full year 2024, our communications business generated over $1 billion in non-GAAP income from operations. Non-GAAP loss from operations for our segment business was $10 million in the fourth quarter. Segment operating losses improved sequentially as a result of the gross margin improvement in the quarter and ongoing cost discipline. Our segment business remains on track to achieve breakeven non-GAAP income from operations by Q2 of this year.
Stock-based compensation as a percentage of revenue was 13%, down 60 basis points quarter over quarter and 240 basis points year over year, as we continue our efforts to reduce equity compensation. Full year 2024 net burn rate was 3.3%, down 160 basis points year over year. As a reminder, this does not include the impact of share repurchases conducted over the course of the year. We continue to manage dilution on a net burn basis, which we define as the number of employee stock units granted in a year net of forfeitures and divided by the prior-year ending share count.
We generated free cash flow of $93 million in the quarter, down sequentially, as we anticipated, driven by incremental vendor prepayments totaling roughly $130 million. As a reminder, we periodically pay certain vendors early to secure favorable terms and pricing. For the full year 2024, we generated $657 million in free cash flow, up 81% year over year and representing a margin of 14.7%, which was up 600 basis points year over year. Before I turn to Q1 and fiscal year 2025 guidance items, I wanted to recap the financial framework we announced at our Investor Day in January.
In 2027, we’re targeting non-GAAP operating margins in the range of 21% to 22%, up 500 to 600 basis points compared with our full-year 2024 results. From 2025 to 2027, we expect to generate $3 billion-plus in cumulative free cash flow. We’re targeting GAAP operating profitability in fiscal year 2025 and each year thereafter. We continue to focus on managing stock-based compensation and dilution responsibly, and we’re targeting stock-based compensation at about 10% of revenue and net burn at less than 3% in fiscal year 2027.
As a reminder, we continue to orient the business to deliver double-digit growth over time, though our framework assumes annual revenue growth through 2027 that is similar to our 2025 guidance of 7% to 8%. Finally, our board recently authorized a $2 billion share repurchase program expiring at the end of 2027, and we’re targeting an average of 50% of our annual free cash flow in capital returns to shareholders from 2025 through 2027. Moving to Q1 guidance. We’re encouraged by the growth acceleration we saw in the second half of 2024, but we’re continuing to plan prudently given our usage-based revenue model.
For Q1, we’re initiating a revenue target of $1.13 billion to $1.14 billion, representing year-over-year growth of 8% to 9%. The quarter-over-quarter decline in revenue reflects both the Q4 seasonality dynamic that we’ve seen in the last couple of years as well as a modest impact from Q4 political revenue. I would also note that there are two fewer days in Q1 versus Q4 and one fewer day in Q1 versus the year-ago quarter. That being said, we continue to feel good about our guidance for the year and we’re maintaining our full-year 2025 organic revenue growth guidance range of 7% to 8%.
Turning to our profit outlook. For Q1, we expect non-GAAP income from operations of $180 million to $190 million. And for the full year, we expect non-GAAP income from operations in the range of $825 million to $850 million. As anticipated, free cash flow in Q1 will be impacted by a roughly $120 million payment related to our companywide cash bonus program that we implemented in 2024 as part of our efforts to reduce stock-based compensation.
This will limit free cash flow generation in the first quarter. That said, we continue to expect to generate strong quarterly free cash flow over the balance of the year. And for the full year, we expect free cash flow in the range of $825 million to $850 million. I’m very pleased with the accelerated revenue growth we delivered in the fourth quarter as well as our ongoing cost discipline that is driving strong profitability and free cash flow.
I’m also encouraged by the innovation we are delivering and the impact new products and features are having both for our customers and on our revenue growth. We are confident in our plans to drive durable revenue growth, continued margin expansion, and strong free cash flow generation in 2025. And with that, we’ll now open it up to questions.
Questions & Answers:
Operator
Thank you. [Operator instructions] One moment while we compile our Q&A roster. Our first question is going to come from the line of Jim Fish with Piper Sandler. Your line is open.
Please go ahead.
Jim Fish — Analyst
Hey, guys, thanks for the additional color here. Thanks for the additional color here following the Analyst Day. Well done again at the Analyst Day. Trying to understand, given some of the macro stuff that’s going on, how much of the strength you guys are seeing in messaging and email is due to somewhat this return of the crypto world.
Aidan Viggiano — Chief Financial Officer
Hey, Jim, this is Aidan. I’ll take that question. So, I’d say from a crypto perspective, we do see those customers exhibiting stronger volume, though it’s, I would say, nowhere near returning to the levels that we saw in 2020 to 2022. So, it’s a bit better, but it’s relatively immaterial to the grand scheme of things.
So, not a big driver for the business, messaging, or email.
Jim Fish — Analyst
Got it. And then just it was nice to see Segment here in terms of like, while revenue was a little bit down year on year, if I look at that deferred revenue build, it seems that implied billings was up north of 20%, if I get most of that over to that side. Is the Segment business seeing a bottom? Or how much is the sort of billing strength attributable to that big deal you referenced?
Aidan Viggiano — Chief Financial Officer
Yeah. Maybe I’ll comment on the — or the RPO, and if Khozema wants to add anything on the business, you can do so. But yes, both the RPO balance you’re looking at, CRPO balance as well, they’re really driven by Segment. And so, the growth really is driven by a combination of bookings growth as well as the percentage of new bookings that are tied to multiyear deals.
And what we saw in the quarter was bookings were up a bit, but also that over 50% of the deals that we booked in the quarter were multiyear. And so, that’s been a point that the team has been working on and focused on, and we’re starting to see that kind of show up in the bookings metric. So, that’s part of what is driving it. And then I would say, I would note that any of these metrics that you’re kind of looking at any of these deals, that they’re 12 months or less in initial duration when you look at the actual metric that you’re looking at on the balance sheet.
So, they’re not fully representative of segment’s book of business. So, that’s a little bit on the metric. I don’t know if you want to add anything on the business, Khozema.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. Jim, all I would say is that I think this has been sort of a steady-as-she-goes story, right? Like I think that there have been a number of operational improvements that we made in the business. I think going back to the operating review that we announced last year, there were a number of things that we wanted to do to improve performance, both on the technology and innovation side, but also in terms of the way that we are running the business. And I think you’re starting to see a lot of that show up in the balance sheet item that you referenced.
And I think, ultimately, that will turn into revenue. I think it’s going to take a little bit of time. Revenue does lag. But I think sitting here today, we feel pretty good about the stand-alone business.
And I think we feel even better about the way that the Segment asset actually contributes to the overall growth story that we laid out during the Investor Day.
Jim Fish — Analyst
Helpful. Thanks, guys.
Aidan Viggiano — Chief Financial Officer
Thanks.
Operator
Thank you. And one moment as we move on to our next question. Our next question is going to come from the line of Michael Turrin with Wells Fargo Securities. Your line is open.
Please go ahead.
Michael Turrin — Analyst
Hey, great. Thanks very much. I appreciate you taking the question, and congrats on the return to double-digit growth. I was hoping you could maybe just spend some time speaking the ways you aim to ensure the growth improvements you’re seeing prove durable.
What are you using to build those initial 2025 assumptions? And then what are some of the swing factors we should contemplate that could keep you at the more aspirational double-digit growth level?
Aidan Viggiano — Chief Financial Officer
Yeah. Maybe I’ll start by kind of what we saw in the quarter. And I think what’s important when we look at the growth in both Q3 and Q4, first of all, it really wasn’t driven by political. In Q4, we talked about it being 60 basis points.
That was largely offset by the end of life of our software business in Zipwhip. So, it’s true 11% operational growth. And importantly, it wasn’t one thing driving it, right? When you look at it by product, we saw strength again in accelerated growth in messaging. E-mail has been strong all year, continue to be strong.
We had a record-breaking Cyber Week with strength in both — in messaging, email, and voice. Khozema kind of gave you some of those stats in his prepared remarks. ISVs were strong, self-service strong. When you look at it by industry, we’ve disclosed the top five at our Investor Day, but we saw strength in tech, financial services, healthcare, retail, e-commerce, advertising.
They all exhibited healthy growth. And then geographically, it was similar. So, I think that’s important for us, right? It’s not one thing that’s kind of driving the strength, but it’s pretty broad overall. From a planning perspective and as we think about what we’re guiding to, which is 7% to 8% for the year, we feel pretty good about that.
We know that we’re running ahead of that, obviously, in the second half of 2024. But just given the usage-based nature of our business, we think that it’s prudent to continue to plan — or smart to continue to plan prudently. In terms of what swing factors could be to drive double-digit growth, as we talked about at Investor Day, that’s how we’re orienting the business today. We are running the place internally that way.
We’re planning a bit more prudently. But we’ll continue to drive those actions internally.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. There’s nothing, Michael, that I would really add. I mean, I think — I’d certainly echo all of what Aidan said. I think when you break it down by some of the channels, like we feel pretty good about the activity there.
I think we referenced during the Investor Day as well as during today’s conversation, the fact that we are seeing a number of AI green shoots. I think that’s pretty positive. I think the most important part of the story, frankly, is, A, that the way that we’re kind of tuning and running the place is toward that double-digit number. And so, guidance aside, like that’s the way that we are running the place.
And then I think on the other side, there’s just a lot of momentum in terms of the number of things that we have underway that’s ultimately going to spring from innovation and technology. But we feel pretty good about the way that things are shaping up. And look, we just did our Investor Day a couple of weeks ago, so we’re just a few weeks on from there. And in the context of the framework, look, we feel really good going forward.
Michael Turrin — Analyst
That’s great. Just as a quick follow-up on gross margin. Know that line can move around a bit, if we’re looking 4Q relative to rest of year, is that more seasonal traffic driven? And are you confident in ability to continue to deliver some level of gross margin expansion as you progress toward those ’27 targets? Thank you.
Aidan Viggiano — Chief Financial Officer
Yeah. So, what I would say — I’ll answer that in two pieces. So, in terms of Q4, we kind of signaled this a little bit coming into the quarter. We always have higher hosting costs in Q4 just given how much traffic is going over the platform.
And so, we provision for that because it’s important to us that we maintain trust with our customers and are resilient in terms of being able to deliver important traffic during things like Cyber Week. So, hosting costs were a factor. You’ll see, if you look from Q3 to Q4 in 2023, that was a similar dynamic. The other thing that happened in the quarter was there was a greater mix of messaging product revenue as a percentage of total.
So, we talked about the fact that business was strong. It accelerated from a growth perspective in Q4. And so, that had a mix effect as well. As you know, that business carries lower gross margins.
Now, as we think about the plan for the framework that we provided at Investor Day and the 21% to 22% operating margin target by 2027, what we said is that assumes basically constant gross margins. We aren’t assuming an uplift in gross margins to achieve those — that framework. Now, is there opportunity over time? I think so when you look at the mix of our products and how many of them carry software like gross margins. But I think the reality is in the near term, messaging mix, both from a product perspective as well as where traffic is terminating geographically, will have an impact.
So, we’re planning for roughly flat gross margins over the next several years.
Michael Turrin — Analyst
Thanks very much.
Operator
Thank you. One moment as we move on to our next question. Our next question is going to come from the line of Nick Altmann with Scotiabank. Your line is open.
Please go ahead.
Nick Altmann — Analyst
Awesome. Thank you. You guys alluded to a large deal strength in Q4. And at the Investor Day, you highlighted how that $1 million-plus customer cohort was, I believe, the fastest-growing.
So, Khozema, can you just maybe talk about the high-end and what’s driving the strength there? Is that more volume-driven? Is it more cross-sell-driven? And then my follow-up is, when you look at the improvements in the communications expansion rate, how much of that is being driven by those larger deals or the high-end customers? Thank you.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. So, let me just step back for a second. I think that as we look at a lot of these larger deals, it’s always going to be a combination of new land and then, of course, expand via cross-sell. But I think what’s really important and interesting for our business, as you kind of think back to the Investor Day, is that a lot more of our customers are seeing value from using multiple of our products, on the one hand, and then I think even more importantly, by using the combination of products, especially as it relates to the way in which communications and data interact and then as we start to use AI.
So, I’d say increasingly, the larger, more sophisticated use cases that we’re seeing deployed, enterprise customers, they’re all kind of heading down that path. But it’s always going to be a combination of expansion through cross-sell, but there are a handful of — more than a handful of new deals in there as well. So, it’s kind of a combination, but I think it’s customers increasingly moving toward our vision. Remind me, Nick, what was the second part of your question related to expansion?
Nick Altmann — Analyst
Yeah. Just on the communications DBNRR. That looked pretty —
Khozema Z. Shipchandler — Chief Executive Officer
How much of it is driven by larger deals?
Nick Altmann — Analyst
Yeah, yeah.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. I think it’s, again, a little bit more broad than that. Like I think the fortunate dynamic that we’re seeing in the business right now, as Aidan alluded to, the trends that we’re seeing aren’t concentrated in any particular area that instead they are broad-based. And so, I wouldn’t per se point to large deals as being the driver.
I would instead say we’re seeing it kind of across the board, and that’s certainly very encouraging for us.
Nick Altmann — Analyst
Great. Thank you.
Operator
Thank you. One moment for our next question. Our next question is going to come from the line of Mark Murphy with JPMorgan. Your line is open.
Please go ahead.
Mark Murphy — Analyst
Thank you very much. The number of AI customers that you’ve racked up is pretty amazing. You had mentioned it at the Analyst Day. Wondering if you could shed light on how much of that is tied to authentication or something that ties into an app download at the front end of the cycle versus something that might align with an ongoing AI usage pattern.
And then is that AI business driving any tangible tailwind to revenue growth? For instance, is that greater than where the political contribution tailwind was?
Khozema Z. Shipchandler — Chief Executive Officer
Say the last part again, Mark.
Aidan Viggiano — Chief Financial Officer
I would say — I’ll answer the last and then maybe Khozema can take the first. It’s not contributing meaningfully. Like I’d say it’s a mix of different types of customers. Some are really small and just getting started on our platform.
Others are larger enterprise customers that are now building different AI use cases. But in terms of the growth rate, it’s a mix obviously across the different group, but I wouldn’t say it’s a huge tailwind to our revenue right now.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. And I think similar dynamic in terms of use cases, I mean, it really — it spans the spectrum there, Mark. I think you certainly do have folks that are doing to 2FA as a part of it. I think one like really good example vis-a-vis usage, 1-800-CHATGPT, obviously, that was a pretty cool use case to launch, so a lot of volume.
I think as well, like you’re seeing a lot of vertical AI start-ups like in a number of different industries that are really trying to ramp up quickly. We see a lot of those companies riding on our infrastructure rails that would be non-authentication, if you will. And so, it really kind of runs the gamut. Like I wouldn’t say there’s like a materially different mix necessarily than the business at large.
But I think what’s most encouraging about it is, again, the fact that we have as many as we do, the way that we’ll be able to grow with these folks over time, I think the folks that are in the vertical spaces, in particular, the ability to use data as well, will enrich those use cases down the road. And again, having broad-based strength here is a good thing.
Mark Murphy — Analyst
Thank you for that. And a quick follow-up for Aidan. Just curious how commonly do you think we’re going to see that — this kind of a huge prepayment? You mentioned the $130 million won recently. Should we think of it as being an annual possibility in Q4 if you’re going to be benefiting from some great terms and conditions? Or do you think it’s going to be more episodic than that?
Aidan Viggiano — Chief Financial Officer
I think it will be more episodic than that, Mark. I mean, we happen to have a large prepayment, you said $130 million, in Q4. I just think that the way we think about it is just given the strength of our balance sheet, this is something we want to continue to do with different strategic vendors from time to time. It really allows us to secure better unit economics and pricing and better terms for the business.
And so, it won’t necessarily be every Q4, to answer your question directly. But from time to time in different quarters, you will see these different prepayments. There’s always kind of a run rate level in the business every quarter. But like I said, some quarters may be bigger than other.
I just don’t want to assume it’s going to be every Q4. It doesn’t necessarily play out that way.
Mark Murphy — Analyst
Very clear. Thank you. Appreciate it.

Thank you. One moment as we move on to the next question. Our next question is going to come from the line of Ryan Koontz with Needham and Co. Your line is open.
Please go ahead.
Ryan Koontz — Analyst
Great. Nice to hear some of your progress in the RCS market. Some early wins there. As we look at this, how would you characterize where the market is today? Can it scale? What are the keys to success here from the industry? Is there a multi-operator interconnect working today? Does it work internationally? Can you walk us through just a minute on where we are? Thank you.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah, Ryan, this is Khozema. I’ll take that. So, I think in terms of where we are, it’s incredibly early. I think, again, you know the story pretty well, like RCS has actually been around for a long time.
I think we’re encouraged by some of the early deployments. But I still think that there are a variety of challenges that still exist in the ecosystem, I think interoperability being one of those. All that said, I think that we’re ready. I mean, we want to support customers.
I think the part of it that we’re actually the most excited about is the branded nature of it. The notion that when you interact with the brand, that you know exactly who it is on the other side. And beyond that, I mean, the engagements themselves are very rich, right, in terms of not having to go to an app or a website or what have you. I think we’ve talked in the past, I think the utility of it has a limited set of use cases depending on how the RCS works.
And so, I think where we are on it is very much ready. We’d be excited if it really took off. I think we’re kind of cautiously optimistic about the way that it plays out. I think we view it as being sort of neutral to modestly accretive to the way that we kind of think about things.
And in some, very, very early days. I think the volumes that we’re seeing, I mean, they’re certainly taking off relative to where they were, but it’s off a pretty low base.
Ryan Koontz — Analyst
I assume the Android ecosystem is kind of far ahead of the Apple ecosystem right now.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah, much further ahead.
Ryan Koontz — Analyst
Got it. Yeah, Android. Right. Thanks so much.
Operator
Thank you. One moment as we move on to our next question. Our next question is going to come from the line of Meta Marshall with Morgan Stanley. Your line is open.
Please go ahead.
Meta Marshall — Analyst
Great. Thanks. Maybe you could just give a sense — I know, obviously, you have a lot of existing customers, and you’ll get idea of their business performance by usage. But just kind of what you’re seeing kind of on the business environment as we start the year just kind of as you go through sales cycles.
And then maybe as a second question, on the Segment piece, the net expansion rate still kind of being below 100%. Just kind of when do you expect some of the new wins and traction that you’re seeing can kind of help improve that metric? Thanks.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. Hey, Meta, I think we feel pretty positive about the business environment. I mean, I think — I don’t want to get ahead of beyond the guidance that we provided, but I think just generally, based on the trend line that we saw in Q4, that customers are ready to engage. They’re excited about the products and services that we’ve got.
I think they’re very excited about the vision that we’ve laid out in terms of the communications plus data, plus AI. I think the fact that there are a number of fielded use cases now and products that go with that, that they can avail themselves of. I’d say pretty positive on balance. I mean, again, I don’t want to get too far ahead of it, but we feel pretty good about the business environment.
I think just one thing I’ll note is we always kind of plan around a neutral macro. So, nothing that we’ve kind of said or — and certainly nothing in the business really, I wouldn’t take from that we’re planning for like a rebounding macro or anything like that. We’re planning for neutral. We’ll certainly be a beneficiary of a higher macro.
And if it gets worse, we could see us get clipped from that a little bit. But we’re planning for neutral. In terms of net expansion, look, we’re not — it’s not like a metric that we per se run the business to. What I would say about it is, is that when we look at some of the key inputs into the way that we think about the stand-alone Segment business, I’d say, number one, we’re seeing a lot more stickiness in terms of the deals because they are more multiyear.
Number two, we’ve done some work on the technology side to get customers activated much more quickly so that they’re getting ROI, I think that certainly helps. And then I think, three, the way in which it now interoperates with some of the data warehouses, which was sort of long a request from customers, like all of that is in place. And I think that all ends up being good for the business. I’m sure you heard the question earlier about the balance sheet dynamics with the business.
We feel better about where it is. I think it’s work in progress. We want to make it even better, of course, and revenue and the — or the expansion characteristics will kind of follow all that.
Meta Marshall — Analyst
Great. Thanks.
Operator
Thank you. One moment as we move on to our next question. Our next question comes from the line of Arjun Bhatia with William Blair. Your line is open.
Please go ahead.
Arjun Bhatia — Analyst
Perfect. Thank you, guys. Maybe the first one, I’ll focus on NRR on the other side of the business, the comp side, the 108 is pretty impressive here. I’d be curious to hear how much of that is improvements in gross retention versus, certainly, there’s been a focus in the business in investing in innovation, product cross-sell, so the split between that would be interesting to hear.
And then how do you expect this to evolve? Is this a sustainable level going forward as some of those initiatives play out? Or is Q4 maybe — so there’s some seasonality in there that we should consider going forward? Thank you.
Aidan Viggiano — Chief Financial Officer
Yeah, I’ll take that, Arjun. This is Aidan. So, the Comms DBNE accelerated to 108% in Q4. I’d say it generally tracks revenue growth, right, if you look at it over time.
But when you break it down, obviously, like I said, we had accelerated growth in messaging. We saw strong performance in email. So, I’d say from a product perspective, largely coming from there. When you break it down between the different churn contraction/expansion elements of DBNE, churn was low.
It has historically been low, continued to be low. We really saw the improvement by — through increased expansion. I’d say a modest reduction in contraction, like that’s how I’d characterize it. When you look at DBNE by our different sales segments, I’d say the two that, I would say, performed really well were ISVs as well as self-serve.
And we talked about them at our Investor Day, those are key go-to-market segments for us. They continued to perform well in the fourth quarter as well. And then by industry, it was a number of different industries, but that gives you a sense of how to think about it a couple of different ways. In terms of how to think about it going forward, I’d just say like it tracks revenue.
We don’t guide to this metric, so I’m not going to provide a specific number, but it will track largely kind of the revenue trends of the company.
Arjun Bhatia — Analyst
OK. That’s helpful. And then maybe zooming out a little bit. At Investor Day, we talked a lot about kind of cross-sell as a big driver of growth.
And I think you had mentioned, I think, 63% of customers are single product. When you think about the cross-sell opportunity, like how do you bucket it in terms of maybe like here’s kind of the layup products that you can sell, and like are there others that are home runs that are maybe longer sales cycles but where customers could significantly increase in size? Like, how are you approaching that from a product and go-to-market perspectives?
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. Hey, Arjun, that’s a good question. I think a couple of answers. So, one is we have concentrated incentives as part of the sales incentive plan to make sure that our teams are focused on it.
And I think they’re excited about that alignment there. I think second thing, kind of to the real heart of your question, like are there — I think the word you used was layups. I mean, it’s never a layup. But I think on some of the easier side, if you will, you would imagine that customers, their ability to use SMS and email in combination, or SMS and voice in combination, like some of the kind of classic channels.
Or if it ever — if it really took off, like with RCS, like being able to kind of reinforce some of that activity with a voice workload afterwards. So, I’d say any one of those combinations, I wouldn’t limit it to those necessarily, but those are pretty attractive. They’re going to end up being shorter sales cycles because they’re already plugged into one of our communications APIs, we can get customers up and running pretty quickly. We have a number of actually deployed use cases in which customers actually get more value by using two channels at the same time or complementary versus just one.
So, we can point to a lot of evidence there too where customers are getting a lot of value. So, I’d say the first part of your question there, like that’s probably on the easier side. I think that said, it’s a little bit longer of a sales cycle. But again, we’re incentivizing our teams to make sure that they’re focused on this too.
That combination of data with communications, like there’s a lot of work that’s going on in our R&D team to make sure that, in the same way that I described like on-ramping a channel, the same way it is as easy to on-ramp data also through kind of a singular or simple set of APIs, if it can’t be done through one. And I do think we’re seeing a lot of interest there. I think it will take a little bit more time. But the easier that we make it, if we can make it completely self-servable, like that’s really where we’re headed with it.
And I think that will start to take off, but that will take some time because of the R&D investment cycle.
Arjun Bhatia — Analyst
All right. Perfect. Very helpful. Thank you.
Operator
Thank you. One moment as we move on to our next question. Our next question comes from the line of Alex Zukin with Wolfe Research. Your line is open.
Please go ahead.
Alex Zukin — Analyst
Hey, guys, I wanted to ask just maybe, again, we’re still early into this whole kind of consistent guidance framework, and coming out of the Analyst Day, where you did a great job. Maybe just talk about how much conservatism, how you’ve thought about conservatism baked into both Q1 and as we get through the year. And then just a quick question about that bad debt expense, the operating income, seemed one-time, that impact in Q4. If you could just dive a little bit deeper into that, those would be the two.
Aidan Viggiano — Chief Financial Officer
Yeah. Hey, Alex, this is Aidan. So, I think, again, we’re really pleased with the performance in the second half of the year, saw strength across a number of different areas. As it relates to the guide for the year, we’re guiding to 7% to 8%.
As we said in Investor Day, we’re orienting the business for double digits. That’s just kind of how we’re running the place. But again, the nature of our business matters, right? We are usage-based. We’re not subscription-based.
And so, with that, there’s a little bit more volatility, a little bit less visibility in terms of forecasting. As it relates to Q1, we’re guiding to 8% to 9% year-over-year growth. That’s one point higher than we guided in Q4. So, you are seeing that these trends that we’re seeing in the second half or that we saw in the second half of ’24 are positively impacting our forecast.
But again, just given the nature of the business, given that it’s a fairly dynamic market, we’ll kind of continue to plan prudently. As it relates to the bad debt expense that I mentioned, maybe just a little bit more color. So, it was a $17 million charge in Q4 related to a Brazilian telecom customer. We really saw a slowdown in their ongoing payment activity.
This is a customer, by the way, that we called out in our 10-Q for several quarters. I think what was different is, historically, they had been making ongoing payments, which limited our — I’d say, bad debt exposure to partial reserves. This quarter, their behavior changed a bit and resulted in a bit more risk. And so, we fully reserved their receivables in the fourth quarter.
So, it was a bit of an unusual for us. It was about a 140-basis-point impact on our margins in the quarter. But like I said, we’re fully reserved on that customer at this point. We don’t expect additional charges related to Oi, which is the name of the customer, in the future.
Alex Zukin — Analyst
Perfect. And then just anything on the competitive environment on the competitive front as you go forward, particularly as you continue to kind of combine the — or level up some of these conversations around the broader platform-based offering?
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. I mean, we feel great competitively, right? I mean, I think we’re the market leader in two really important categories. I think you’re seeing some of the recent success that we’ve had, especially in what I think is going to be really a secular trend around AI, like that’s very encouraging. We’re growing at a faster clip than any of the other guys.
And I think we want to take that strength and not rest on our laurels but instead convert that energy into new R&D investments, which kind of lead to a double-digit mentality over time. And I think that’s going to be a really good setup for the business. And I think some of the R&D investments that we’re making are really exciting and they’re going to unlock a lot of value for customers.
Alex Zukin — Analyst

Operator
Thank you. One moment for our next question. Our next question comes from the line of Patrick Walravens with Citizens JMP. Your line is open.
Please go ahead.
Pat Walravens — Analyst
Great. And let me add my congratulations. Aidan, can you remind me how to think about the operating margin ramp from like 17% to 18% in ’25 to the 21% to 22% in ’27? I mean, I have ’26 pretty flat currently with ’25. Is that the right way to think about it?
Aidan Viggiano — Chief Financial Officer
What I would say, so we committed to 21% to 22%. You know that given the guide that we gave for 2025, that implies roughly 17.5% in 2025. So, you should assume accretion each year. We didn’t give specifically how to think about ’26 and ’27, but you should assume that each year we get a bit of accretion on margin rates.
So, if we’re going from 17.5% to 21% to 22%, that gives you a sense of how to model kind of ’26 and ’27.
Pat Walravens — Analyst
OK. I’ll go in the middle. And then, Khozema, where are you — can you maybe give us some examples of where you’re using agents internally? You reeled off a number of areas during the Analyst Day. But where is it — where are you finding it’s really working? For your own internal operations.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. Good question, Pat. So, I think there’s two areas where we’ve seen really a marked difference in the way that we’re operating. I think the first would be in customer support, where we’re seeing a significant amount of deflection as a result of employing AI agents.
That’s made the workforce a lot more productive on the one hand. But on the other hand, it’s also gotten customers to an answer much, much faster in an effectively self-serve fashion. So, that’s been very exciting for us, and we’re going to obviously continue going deeper there. The other side of it though is with respect to SDRs.
So, instead of necessarily attaching a person to every incoming inquiry, we’re able to vet a lot of those now through, again, AI agents. And the reason that one, I think, is even more impactful in some respects is, obviously, there’s cost savings, but more importantly, when the rep attaches themselves to the vetted account, it’s just that it’s been vetted, right? So, it’s a much more high-quality lead so that the rep ends are pursuing business that’s probably going to materialize versus just chasing something that happened to come in.
Pat Walravens — Analyst
Great. Thank you both.
Operator
Thank you. One moment as we move on to the next question. Our next question comes from the line of Ryan MacWilliams with Barclays. Your line is open.
Please go ahead.
Ryan MacWilliams — Analyst
Hey, guys, thanks for taking the question. I’d love to hear about how you’re seeing any changes in the macro through the end of the fourth quarter or to start this year and if you noticed any changes from a usage perspective from a geographic standpoint in North America versus the rest of the world.
Aidan Viggiano — Chief Financial Officer
Hey, Ryan, I’ll start. So, I’d say nothing I’d call out specifically from the end of Q4 through kind of early Q1. What I will say is, for us, you always see a drop-off in volume because you’re coming off of a very high holiday season. That’s not atypical this year.
That’s just kind of the seasonality of our business. So, I don’t think there’s anything I’d call out specifically U.S. versus rest of the world as it relates to the volumes I’m looking at kind of daily.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. No, I agree with Aidan. I mean, there’s obviously a lot going on, it’s dynamic. But I don’t think that we’ve seen necessarily anything that would really impact our business thus far.
Ryan MacWilliams — Analyst
Perfect. And then Khozema, voice AI, we’re still really early days, and I’m sure this is going to change like 10 different times over the next few years. But as we think about like the potential voice AI use cases that would make sense for Twilio versus might make sense more like over-the-top via like Siri or Alexa or something, like what use cases do you think — or have you seen early days that people want to use Twilio for and that you guys are the rails for your customers? Thanks.
Khozema Z. Shipchandler — Chief Executive Officer
Yeah. I’ll give you maybe like an anonymized example. I mean, I think that we have customers who are actively in beta and piloting different use cases right now. So, basically, I mean, think about it this way, right? You have a customer who previously may have been using an IVR as the mechanism to handle an incoming workload.
And in many instances, at some point, that IVR has got to then flip to a human agent who’s got to be able to handle like whatever that transactional workload is. And when that happens, the only measure, really, of what’s going on there is cycle time. And not only is it just cycle time, because of the fact that that’s the case, there’s no real opportunity to drive a more interesting, intimate upsell-type experience. And so, the customer that I’m specifically referencing in this case, what they’re doing is that they’re using the voice product that they were but layering on top of that our voice intelligence capabilities.
So, all of the traits from that call are getting stored. They’re using AI on top of it so that, instead of even going into an IVR, the AI agent is handling it from start to finish. In addition to that, because it’s an AI agent, you’re not paying a person to handle that volume, and so there’s no constraint on cycle time. And so, you can create that much more interesting and intimate experience.
And then finally, what’s especially interesting in this particular case is that it allows time for upsell, right? And so, using some of the data that can be referenced from prior transactions and data history with that particular customer, you can use that data to go forward and say, “By the way, you ordered X, Y, Z last time. Here’s an opportunity to do it the next time.” And it drives more volume, ideally, higher-margin volume for those customers. And on the back end of that, we can actually add a channel too thanking them for their business on the other side. So, that is a kind of real-life one that is in motion right now.
It’s not a singular example. We’re starting to have that conversation with a number of our other customers as well. And I think that is right at the heart of this idea of communications plus data, plus AI, which is why we’re so excited about it, is that we are actually starting to see the green shoots.
Ryan MacWilliams — Analyst
That sounds much better than being stuck in IVR. Thanks. I appreciate the color.
