TWLO - NYSE

Hello, and welcome to the Twilio Inc. First Quarter 2024 Earnings Conference Call. [Operator Instructions] Please be advised that today's conference is being recorded. It is now my pleasure to introduce Senior Vice President of Investor Relations and Corporate Development, Bryan Vaniman.

Good afternoon, everyone, and thank you for joining us for Twilio's First 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-K and our forthcoming Form 10-Q. 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. With that, I'll hand it over to Khozema and Aidan, who will discuss our Q1 results, and then we'll open the call for Q&A.

Thank you, Bryan. Good afternoon, everyone, and thank you for joining us today. Twilio had a solid start to the year, exceeding our Q1 guidance, delivering $1.047 billion in revenue and $160 million in non-GAAP income from operations. Our teams executed well across the board in Q1 as evidenced by a record quarter of non-GAAP gross profit of $566 million, a 54% year-over-year increase in our non-GAAP income from operations, and another strong quarter of free cash flow of $177 million. We are in the early stages of reinvigorating the business and are optimistic about our progress thus far. In fact, we're executing with greater discipline, rigor and focus on innovation than ever before. In the last 5 quarters, we've begun delivering significant non-GAAP operating profitability. In the last 4 quarters, that's been paired with significant free cash flow, and we are committed to additional operating leverage and accompanying free cash flow. In the meantime, we are also making new targeted R&D investments that we expect to reaccelerate growth over time. In March, we announced an accelerated target for GAAP operating profitability to Q4 2025, and we also announced that the Board authorized an additional $2 billion of share repurchases, bringing our total share repurchase authorization to $3 billion. This is a reflection of the board's confidence in our strategy and the opportunity ahead. As of today, we've repurchased approximately $1.5 billion of shares, and we're targeting to complete the remaining $1.5 billion of repurchases by the end of this year. At that same time, we also completed our operational review of Segment, and the team is focused on executing the plans we outlined, including more focused product innovation, embedding Segment's capabilities into Communications products, and the commitment to getting Twilio Segment to breakeven on a non-GAAP operating income basis by Q2 2025. We are making progress in each area. Across the board, we're innovating and releasing new products, many of which are underpinned by CustomerAI, our predictive and generative AI layer. Finally, we welcomed a new bench of leaders to Twilio, who will play an important role in shaping the next chapter of our company as we operate with greater financial discipline, operational rigor and focus on innovation. And now let's turn to our business highlights. Our Twilio Communications business had a strong first quarter with revenue of $972 million, up 7% on an organic basis year-over-year and representing 93% of our overall revenue. During the quarter, Communications landed meaningful customer wins, released new products and deepened our relationships with ISVs, partners and resellers. With this disciplined approach, we're focused on growth levers that we believe will drive reacceleration in both the short and long term. In the short term, our growth will be fueled by expanding our network of ISVs and global partners, driving more self-service and cross-sell momentum and extending the value that we're delivering to customers. In Q1, we signed a 7-figure partner agreement with China Unicom, one of China's wireless carriers, who will resell a majority of our Communications products for its enterprise customers across Singapore and Hong Kong. We also signed a partnership with Bloomreach, a leader in the marketing automation space and will be working with them to co-sell Twilio products. Over the long term, our focus on innovation will unlock more value for customers, creating stickier relationships and ultimately expand Twilio into new markets and larger deal sizes. We made progress on a number of our AI products and are driving better synergies with our Communications and Segment products. In Q1, we announced Agent Copilot, our first of 3 launches in 2024, where Twilio will natively embed Segment into Twilio's Communications products. With Agent Copilot, we've embedded Unified Profiles powered by Segment within Flex, giving agents deeper insights into their customers' behaviors and preferences. By accessing the real-time data from Unified Profiles, Agent Copilot assists in intelligent routing to agents and provides them with actionable insights for each customer interaction, automating and enhancing agent productivity while reducing resolution times. Agent Copilot and Unified Profiles are currently in public beta, and customers like Universidad Uk are already leveraging these capabilities within their contact centers. As a result, they've driven a reduction in handle time by 30%. And by using our embedded AI automation tools, they've been able to deflect 70% of support cases in just 2 months. While it's still early, these results are impressive as it illustrates how our customers are able to quickly realize tremendous business value at scale when combining Segment within our Communications capabilities. Our customers also continue to realize tangible benefits when using our other customer AI innovations, including Voice Intelligence, which has gotten a great response from our initial public beta customers. With Voice Intelligence, brands like PGA of America are leveraging transcriptions for their customer support interactions within their Flex instance, getting valuable data insights from call recordings. Of the hundreds of customers that have deployed Voice Intelligence, over half are using language operators, which allows brands to trigger an action based on any keyword, allowing for better personalized communications. We also recently introduced language operators that uses generative AI and large language models to determine the best sentiment for the overall conversation so brands can get a better sense of where escalations or customer churn may take place. And we're continuing to embed AI capabilities into our verification products. We currently have over 11,000 customers leveraging Verify Fraud Guard. And in Q1 alone, Fraud Guard blocked more than 62 million fraudulent messages. We are not only saving our customers money, but we're also ensuring our customers and users have a seamless experience. During the quarter, we signed a competitive deal with Bluesky, a social media app, which recently launched its app to the public. They chose Twilio's Verify API to ensure a seamless and secure sign-up process for new users. At launch, the company saw an impressive amount of sign-ups, gaining almost 800,000 new users in one day. And Fraud Guard not only helped save the company hundreds of thousands of dollars, but it ensured new users received secure authentication. Now turning to our Twilio Segment business. For Q1, Segment revenue was $75 million, up 2% year-over-year. It was a challenging quarter, but we came out of our segment operational review in March with greater clarity around a short list of priorities that we believe will address the underperformance of Segment. We will continue to focus on rationalizing our investments to rightsize Segment's cost base, accelerating time to value for customers by using AI to automate onboarding and enhancing data warehouse interoperability, delivering 3 products in 2024 that natively embed Segment into Communications and capitalizing on CustomerAI momentum. In the month following the review, we've already made meaningful progress against all of these areas, and we believe that we have the right set of plans in place to turn this business around, address churn and contraction and improve its financial performance. We are also committed to getting Segment to breakeven on a non-GAAP operating income basis by Q2 2025. During the quarter, we deepened our partnerships with Databricks and Snowflake. With Databricks, we launched a new bidirectional integration that allows customers to seamlessly ingest and activate data. We are on track to deliver further enhancements to our data warehouse interoperability offerings across partners in Q2, and as mentioned earlier, we delivered focused product innovation like Agent Copilot that demonstrates Segment's value when it's natively embedded into Communications. CustomerAI Predictions is continuing to get adopted by new customers, and since its GA in Q3 2023, more customers are realizing the benefits and positive material impact to their businesses. For instance, XP Inc., a Brazilian investment management company, said that since implementing CustomerAI Predictions and by using our out-of-the-box tools, they've been able to save their team 4 weeks of data science work and improved audience engagement and conversion rates. Looking ahead to Q2, we'll bring our second product that natively embeds Segment into Communications into beta, which further demonstrates the value we can deliver to our customers by combining Segment data with our Communications products. Before turning things over to Aidan, I want to take a moment to welcome the new leaders that have joined my management team. During the quarter, we welcomed Inbal Shani as our Chief Product Officer for Twilio Communications; and Thomas Wyatt as our President of Segment. And yesterday, Chris Koehler joined as our Chief Marketing Officer. We've also taken a thoughtful approach to evolving our governance practices. First, we welcomed Andy Stafman, a partner at Sachem Head Capital Management, to Twilio's Board of Directors. And second, we announced in early April that we plan to hold an Investor Day within the next 12 months, at which time we'll share an updated medium-term financial framework and set of targets. And finally, we recently submitted a proposal for the declassification of our Board, which will be voted upon at our Annual Shareholder Meeting in June. In summary, we're making a lot of progress in a very short period of time, and we're continuing to drive significant change. We're maturing as a company and as a team, we're making deliberate decisions with discipline, rigor and focus to deliver attractive levels of growth and profitability over the medium term. While we've started to see positive impacts from some of these changes in our recent financial results, others will take longer to bear fruit, but we are confident that the opportunities we pursue will create meaningful value for all of our stakeholders and allow us to deliver on our commitment to drive durable, profitable growth over the long term. And with that, I'll turn it over to Aidan.

Thank you, Khozema. In Q1, we exceeded our guidance on both revenue and non-GAAP income from operations and delivered our fourth consecutive quarter of solid free cash flow generation. Q1 revenue was $1.047 billion, up 4% reported and 7% organically year-over-year; Communications revenue was $972 million, up 4% reported and 7% organically year-over-year; and Segment revenue was $75 million, up 2% year-over-year. Our Q1 revenue growth was impacted by the crypto headwinds that we've referenced in the past several quarters as well as the sunsetting of the software component of our

[Operator Instructions] Our first question comes from the line of Jim Fish with PSC.

This is Quinton on for Jim Fish. Maybe first, how are you looking at kind of the bifurcation between budgets or demand strength across, call it, your mid-market and commercial versus your more enterprise customers at this point? Is the willingness to spend very similar across those 2 verticals? Or are you seeing significant strength or weaknesses across one or the other?

Yes. I would say that, in general, we're seeing kind of demand volume kind of hanging there across the board. I think that the growth profile that we've seen with most customers continues to be pretty good. There's a couple of pockets, I'd say, especially with respect to internationally terminating traffic, where we're seeing a little bit more weakness. But I think that as you look at most of the industries that we end up serving, we are seeing year-over-year growth. Obviously, there's some noise in our business with respect to what we've got in terms of

Got it. And then, Aidan, maybe for you. Gross margins here was a bright spot for sure. Can you talk about why this wouldn't be a kind of sustainable uplift? Understanding some benefit from product mix, but why couldn't we see this kind of upside continue through the rest of the year?

Yes, sure. So we saw gross margins up 170 basis points quarter-over-quarter, with both business units up as well. So a couple of dynamics. First, on the Communications side, which is the business that carries Twilio at this point. They were up 150 basis points quarter-over-quarter. Part of it was what you said, which was the favorable mix between U.S. and international. As Khozema just mentioned, we did see lower international terminating traffic. So that has a benefit to gross margins because we know gross margins, as we've communicated in the past, are lower internationally than domestically. We also had, in this quarter, as I said in the prepared remarks, some benefit from credits related to hosting spend. That benefited Q1 by about 80 basis points. We don't expect it to continue. And so I'd say the combination of those 2 things, the hosting credits not continuing as well as the fact that mix isn't necessarily controllable by us is kind of how I think about gross margins going forward, Quin.

Our next question comes from the line of Mark Murphy with JPMorgan.

Khozema, I was -- thinking back prior to the business review, our sense was that the Segment business could preserve some of the AI optionality, because you can combine that with Comms, as you mentioned, and then the broader CustomerAI vision. Just recognizing it's sluggish overall in that business, is Segment seeing some usage for pulling customer data into LLMs? And I'm also wondering about that because you did mention the Databricks connectivity. I was just trying to understand what kind of projects those are, and if you're seeing more of that in the pipeline? And then I do have a very quick follow-up.

Yes. Good question, Mark. So there's kind of 2 dynamics there. So I think the first is that with respect to Segment specifically, like one of the things that we committed to as part of the operating review was to make sure that we were able to combine some of the data elements of Segment with the Communications capabilities that we have. We launched that product. It's called the Agent Copilot. That Agent Copilot uses something that we refer to as Unified Profiles. And so basically, what that allows for is, is the ability for an agent to be able to absorb information during the context of a call, for that data to be stored subsequently, and then for us to be able to create a flywheel so that every subsequent interaction with that consumer and then with consumers more broadly for one of our customers, they are able to get value out of that, fundamentally reduce cost, have a better customer experience. And that kind of creates like a generative flywheel, if you will, where Segment is continually used through the Unified Profile, if that data is then subsequently fed back into the Copilot, and then that flywheel just kind of keeps on turning. And so that's how I kind of think about the optionality with respect to Segment. We committed to 3 products actually during the course of the year. We've delivered one. We kind of alluded to the second one being on track for the upcoming quarters, so we feel pretty good about our progress there, too. And then I think more broadly, like there's a number of generative AI elements, both within Communications as well as Segment, and those things are happening nicely. The other part of the question that you asked about was Databricks. And with Databricks and Snowflake, actually, one of the priorities that we also laid out as part of the operating review was to establish greater data warehouse interoperability with those folks as well as the other big data warehouse players that are out in the market. And so the way that you should think about some of the announcements that we made as part of the release today is that fulfilling on that exact same road map that we articulated about 1.5 months ago, we're making the progress that we intended to make. We're starting to see traction with those 2 players, in particular, you asked about Databricks, that allows us to basically seamlessly offer data back and forth on behalf of our customers who may be already Databricks users. And so we think that, that's additive, not just to Segment but increasingly to the entire enterprise as we leverage the combined capabilities of Segment Communications.

Our next question comes from the line of Meta Marshall with Morgan Stanley.

Great. Maybe following up on Segment, understanding kind of the product rollouts that are happening, but maybe just -- we're about 60 days in to new leadership there. Just any thoughts of new leadership as they've gotten in and how to improve the go-to-market there? That would be helpful.

Yes. Good question, Meta. So I'll just kind of answer your question more generally, and then I think more specifically about Thomas and I think the leadership that he's brought. So I think in terms of the business, we've started to take steps in terms of our path towards the non-GAAP operating profit target that we established for Q2 '25. And we feel like we're on track for that. We're making good progress. That path isn't necessarily going to be linear. And while we're seeing good progress in terms of bookings, that's going to take some time to kind of catch up and ultimately show up in the revenue line. And so there's like sort of some dynamics there. In the meantime, we're going to control our costs and be very focused about the R&D areas of prioritization. In terms of go-to-market, before I get to Thomas, we are starting to see some green shoots. There's a couple of customers that we referenced in our talk track. I think we're very excited about the nature of those customers, what they do, our ability to grow with them. I think in particular, what we're very excited about is our ability to deliver time to value for those customers. significantly faster than, I think, where we've been historically. I think in the past, that has taken us up to 6 months, in some cases, to be able to get to value initially. And I think we're starting to see some -- several instances, actually, where we've been able to achieve that in as fast as 30 days. I think Thomas has been an awesome addition to the leadership team, quite frankly. With respect to all of our leaders, I feel very, very strong about our leadership bench overall. But in terms of Thomas specifically, given his deep knowledge of the product, just given his background where he focused both on sort of product as well as marketing, which is useful because the marketer often tends to be the buyer in some of these instances. I think that's been a real accelerant in terms of the progress that we expect. And I think just in general, it's provided some stability and focus, which is also something that we're very geared towards, with respect to Segment.

Our next question comes from the line of Taylor McGinnis with UBS.

I'm hoping that you could provide a little bit more color on what's driving the slower organic rev growth guide of 4% to 5% in 2Q. So it looks like crypto revenue in 1Q is actually higher than 4Q. So that, combined with some of the other headwinds you might be lapping, you would think that, that would lead to accelerating growth. So can you just maybe comment on why that might not be materializing? And at the start of 2Q, has there been any deterioration in the macro or anything in the demand environment that might be driving some of that?

I'll start, Taylor, and if Khozema wants to add, he can. So a couple of things to call out. So we have largely lapped crypto at this point. We don't expect it to be a headwind in Q2. We do have some product-specific dynamics that we called out for. So as we've said, so first, Segment's revenue was 2% in Q1 from a growth perspective. We expect it to be muted for the year. As Khozema said, we're working on a number of different initiatives there, but they'll take time to kind of show up in our financial results. We also have some noise from the end of life of our

Our next question comes from the line of Alex

I guess maybe any [ better ] changes in the competitive environment internationally? And then domestically, again, it sounds like a stabilization in messaging volume. Is that more of a mix shift towards SMS and personalized messaging as a [ brand of ] calling? Curious what's helping kind of drive that NRR stabilization. And then just a quick follow-up.

Yes, Alex, I'm just going to repeat back the question because we had a little bit of difficulty hearing you. So the way that I heard you ask it was whether or not we were seeing any changes in the competitive environment, international or domestically, then it sounds like to you that there was stabilization of messaging volumes, and then is there more of a mix shift towards SMS, precise messaging, basically what's kind of driving NRR stabilization? Did we hear the question right?

Yes, you did.

Okay. So in terms of the competitive environment, maybe I'll just take that one first, I wouldn't say that we've seen any real changes there. I think that as Aidan alluded to in her prior answer, we have seen a little bit of softness in terms of internationally terminating traffic. I think from our perspective, like we always want to maintain price discipline about the way that we think about those markets. And so that's kind of what we've seen. Otherwise, the volumes across the board have been more or less stable, but they haven't inflected. And I think that's kind of impacting some of the growth dynamics as we look forward. There's a bunch of new stuff in the hopper that we're kind of thinking about and executing against. It will just take a little bit of time for that to show up in some of the growth numbers. In terms of mix, I wouldn't say that there's like anything significant happening in mix other than what we've already talked about in terms of as international weakens a little bit and you see strength in domestic, that's obviously going to have an impact on gross margins, but I think as it relates to more personalized messaging over time, I think that is certainly our expectation, especially as we pull in Segment into more of our Communications workloads. I think we're already starting to see examples of that with customers wanting to deliver much more personalized communications using data. I think you'll see more of that through some of the products that we kind of called off. I think Agent Copilot with Unified Profiles is one, but Voice Intelligence, which we've been kind of using within the confines of voice itself is another. And I think increasingly, you'll start to see a lot more personalized communications. I think that's the way that generative AI is really going to accelerate our business and some of the impacts that we see with customers fundamentally to reduce costs and generate better outcomes.

Makes sense. And then on the OpEx side, obviously, some kind of moving pieces here in Q1 and Q2. But where do we -- as you guys think about kind of the balance of both getting the most leverage out of the model and where are you actually hiring and investing incremental dollars, how should we think about the hiring targets for kind of the next kind of incremental year or 2 quarters?

Yes. I can kind of take the question more generally. I think that we don't feel like we have significant headcount needs right now. I mean obviously, we go through kind of the normal process of backfilling and stuff like that, but we're not looking to do any material adds. I'd say that our priorities right now have been around R&D. It's just kind of replenishing the pipeline there. We have a number of really focused projects in both Communications and Segment that we do expect to bear fruit over sort of the medium to long term. And I think that over time, this will start to show up in some of the growth numbers. I think other than that, I wouldn't really expect anything around OpEx other than what we've called out in the past, which is we've got this bonus program that we've obviously rolled out across the business. That's kind of a near-term impact on OpEx, but I think you understand the dynamics there and the way that, that impacts stock-based compensation over time. But otherwise, I think we feel pretty good about the cost basis that we've already got. And I think just one last thing maybe I'll add is we still see opportunity in terms of like geo diversification of the roles that we're hiring. And then I think the last one is like automation, right? We're obviously doing a lot with automation for customers, and we would expect that a lot of those same workloads that we're offering externally should have positive benefits as [indiscernible] to Twilio as well.

Our next question comes from the line of Ryan Koontz with Needham & Company.

I wanted to follow up, if I could, on Alex's last question there about the competitive dynamic. And how would you explain kind of what's happening with registered and unregistered messages these days? I know you are a leader, certainly, in driving toward that. And how is that impacting the competitive landscape today? And is there any -- what's also your perspective, I guess, on the opportunity around political messaging as it relates to the election coming up?

Yes. A couple of questions in there, Ryan. So let me take the political one first. So I think in 2024, generally, obviously, we're in the middle of an election season cycle, we'll generate some revenue from political customers, but we don't really anticipate an expected outsized impact as a result of the race. Just as a reminder, we have registration requirements and an acceptable use policy in place that we expect all of our customers to follow, especially as it relates to opt-ins. And that really just sort of ensures the quality of traffic on our network. It protects consumers. And so we're not going to accept any business where that policy is not being properly followed during this upcoming cycle. And we think that's in the best long-term interest of the business and the best long-term interest of certainly the American consumer, but that has actually global implications as well because we're taking kind of the same stance in most markets. That's kind of a good segue to the dynamic that you asked in the first part of your question, the whole 10DLC thing is entirely behind us. We went through that process last year. I think we felt a very small impact as a result of that. And so I don't think that there'll be really any impact as a result, and toll-free is kind of a nonissue as well because that got done at that point as well. And then finally, just in terms of competitive dynamics, like I don't really think it alters anything other than the feedback that we receive from our customers is that, a, they want to work with a trusted provider, and so we think that we benefit from using compliance, not just to sort of our regulatory posture but actually as a unique selling point of the business; and b, I think increasingly, they want to work with someone who doesn't just prosecute that traffic in that fashion, but also ensures that no fraud or anything of that nature is being committed as well, which is where our AI tools and the like can really play a role in helping our customers with their traffic and ensuring that it's clean.

That's really great, Khozema. And just a real quick follow-up. On the A2P side, is that relatively stable now? Or are those still inching up?

I'd say it's relatively stable at this stage. There's nothing kind of new to talk about since, I don't know, a couple of years ago, I guess.

Our next question comes from the line of Samad Samana with Jefferies.

Awesome. This is actually Billy Fitzsimmons on for Samad. I'll [ give you ] pretty quick. Intra-quarter, you gave an organic growth target range and [ reaffirmed it ] today. Can you just remind us what that growth range kind of assumes in terms of macro dynamics as you progress through the year?

Yes. So we've seen relatively volume -- stable volumes, Bill, as we've talked about. And I'd say as you think about kind of the range of outcomes between the low end of the range and the higher end of the range, I would say volumes -- if we did see any erosion kind of overall in volumes, I would say that would kind of get you to the lower end of the range. Conversely, if we started to see volumes in Flex up and we continue to execute on our cross-sell initiatives and expansion with ISVs and the different initiatives that we're working on, we could see volume and revenue at the higher end of the range. What I would say is that -- I said this before, but regardless of where we are in the range, we're going to deliver on the profit and free cash flow. We're very intent and focused on that. We were kind of very zeroed in regardless of where we land on the revenue range.

And our next question comes from the line of Michael Turrin with Wells Fargo.

Just on the Communications customer metric, that had ticked down a bit Q3 to Q4 and picked back up in Q1. So I'm just curious if any of that is definitional, just tied to the splitting of segments, or if that is a return to just a bounce back in customer activity on the core Communications segment.

No, it's not definitional. It is, I would say, the bounce back, given the 2 options that you gave me there. But what I would just say overall is that this metric represents -- is anchored to a minimum $5 monthly revenue spend. And so we have a large number of active customer accounts with relatively low individual spend that, in aggregate, do not drive like a significant portion of the revenue. So it has nothing to do with definitional. It's a bounce back, I guess, in terms of the customer count, but I would just say the relative importance of this metric given the size and the scale of the business at this point, and we're talking about a $5 threshold, I don't think it's probably the most relevant metric today. Just [ kind of ] the size of the business and how much we've grown.

On Segment, just how should we think about the time line to get that piece of the business to a good foundational cost base to restart from? Obviously, there had been an evaluation period. So now going forward, how should we think about the time line of where you've gotten to at least sort of a good foundational restarting point, if you will.

From a cost perspective, Michael?

I think so. Yes, I mean just when you feel like the -- I mean, obviously, there are some moving pieces there, but when you feel like the sort of the foundation is in place of at least the initial efforts in rebuilding that business.

Why don't I start with the cost side and then Khozema can talk more around all the actions that we're taking? What I would say is the business lost $21 million in the first quarter. That was actually up a little bit versus the fourth quarter. We have a path to get that business to breakeven by the second quarter of next year. What I would say is we don't expect this to be completely linear, right? We have a number of initiatives that we're working on. Khozema talked about the product from a product perspective, getting to data warehouse interoperability. There's a number of things we're working on with regards to time to value. So we intend to incur some costs to deliver on those objectives, but we will get to the breakeven by Q2 of 2025. It's just that decline for Q2 2025 won't necessarily be linear. So we have plans in place, but I just wanted to put that out there, so you know how to think about that and model it.

Yes. The only thing that I would add there, Michael, is that this management team has been quite good about meeting targets that we set out for ourselves, and nothing's changed about our ability and confidence in being able to get to non-GAAP breakeven by Q2 '25 of next year. In the meantime, there are a number of other things that we also committed to that were more operational in nature, data warehouse interoperability, delivering a combined Segment, Twilio offering, making sure that we had a number of additional things like that on our road map upcoming, improving our time to value. And against each of those operational areas, we're actually making quite good progress. And again, as you alluded to, there are some dynamics here in terms of both revenue and cost. And some of the revenue dynamics are going to just take a little bit of time, given the nature of how bookings have to kind of catch up. But we are seeing green shoots. We are seeing interesting new customers. And I think as we continue to execute on the operational items that are important to the future of the business, I think we feel increasingly confident that Segment is a really important asset to Twilio, that data is going to play a really critical role in terms of the way that we're going to deliver customer outcomes. And I think you saw the first one of those with this Agent Copilot that we released using Segment and Comms in Q1.

And our next question comes from the line of Ryan MacWilliams with Barclays.

This is Pete Newton for Ryan MacWilliams. Just a question on the sales side. Maybe how has sales efficiency and rep execution trended recently? And is this efficiency level in line with just internal...

We have a little bit of a bad connection to you. Could you try again?

Is this better?

Yes.

Perfect. Just a question on the sales side. How has sales efficiency trended recently? And is this in line with internal expectations? Maybe if you could delineate between sales efficiency on the Segment side versus the Communication side, just so we can get a full picture.

Yes, I think on the Communications side of the house, it's in line with where we expected it to be. There's -- the team's executing. We have reoriented that team to gross profit dollar generation, for the most part. I'd say probably 80% of the team is measured on that. And they're performing kind of in line with expectations. On the Segment side, we are kind of in a bit of a rebuild here. I'd say bookings came in, I would say, a little lighter than we want to see like longer term in the Segment business in Q1. But the team has a number of actions in place, and Khozema has kind of talked about them several times now, so I won't reiterate them. But it's going to take a couple of quarters for Thomas and the team to get that business back and humming kind of where we want it to be, and it will take some time for that to show up in the financial metrics.

I think sales efficiency generally has been pretty good. I mean we obviously took some very significant cost actions last year. Revenue line continues to grow. As Aidan mentioned, we're anchoring everybody against the gross profit dollar metric, and we think that's important to be able to incentivize the sales force. And so I think that combination of things has yielded a lot of the operating leverage that you've seen over the last year, which we continued into Q1. And obviously, a lot of that now is starting to translate to really significant cash flow, which feels quite good.

And our next question comes from the line of Arjun Bhatia with William Blair.

Just one quick one for me. When we're thinking of some of the Segment plans that you had laid out with the deeper integration as well, and I think you touched on some of this a little bit. So curious like how long -- I know there's quite a bit still left to do here, but how long before we start to see results from some of that flow through to enhance the Comms business? Is that something that the '24 outcome, or with some of the products work still to be done, something that maybe we should expect in '25 and beyond?

Yes. I mean I think we have to delay a little bit between when it shows up in our financials versus how customers are starting to get value from it. But we cited an example in our earlier remarks about how, when a customer fielded the combined capability of Segment inside of Communications, that was a specific contact center environment, it was a really powerful outcome, right? They were able to reduce their cost by about 30%. They were able to increase their deflection rate by about 70%. And what's at the core of this is fundamentally, how do we deliver a better outcome for a customer at a materially lower cost point for them overall. Now some of that value obviously accrues to us because we'll be able to kind of upsell, using AI, some of these different products that we're trying to uplift. So I think that, in general, we feel pretty good about the customer delivery. And again, we'll use examples like that to kind of prove that this adds really demonstrable value to customers. We'll continue signing new logos on that basis over the next several quarters, and then those bookings will just take time to turn into revenue. But so far, so good, and I'm certainly very encouraged by some of the early examples.

Our next question comes from the line of Michael Funk with Bank of America.

So on the international softness that you cited, I'm curious how much of that is due to shift in traffic, so to RCS and WhatsApp, for example, versus a reduction in traffic volume.

Yes. I wouldn't say it's due to a shift in anything actually, Michael. I think that it's -- they're just a little bit soft from a kind of demand environment perspective in terms of that international termination. I think in terms of RCS, more specifically, like we haven't really seen significant activity there yet. We certainly expect RCS to play a role down the line. I think if anything, it will probably be accretive to the business, but that's not what we saw in international volumes.

That's very helpful. And one more quick one, if I could. Thank you for the color on Agent Copilot embedding Segment and more of the Comms products. For clarification there, are you charging additional or separate for the embedding of Segment? Or is it more of a teaser to get customers more familiar with Segment and hopefully drive churn lower, higher usage and engagement and interest in that product over time?

Yes. Ultimately, it will result in a price upsell. There's like a lot of details. But just to answer your question in short, it will fundamentally result in a price upsell. There's a number of like kind of packaging and pricing considerations that kind of go into how we'll ultimately take some of these products to market, but the short answer is it will ultimately result in increased price.

Okay. But in the short term, as you initially launch, there is no price increase. It's simply embedded in the product. But over time, there will be separate SKUs or pricing. Is that correct?

When it's in private beta, we typically offer it for like a teaser period, where there's not as much of a price increase. But once it kind of goes out of the private and it's fully GA-ed and the customer is actually using it beyond kind of the test period, then there is fundamentally a price increase that goes into effect. So it's not meant to be just protective. It's meant to be value-enhancing and therefore, with the price uptick.

Our next question comes from the line of Peter Weed with Bernstein.

One of the things that you changed in Communications here recently was grouping in Flex and some of the marketing in with Communications. And I'm wondering how much they may either be benefiting or dragging on the Communications business, if we just looked at what would be isolated and what we might have been looking at in the Communications business more historically.

I think your question was when we moved over Flex and marketing campaigns to Communications, is there like a -- well, just to be clear, like when we talk about Communications, we talk about it on an apples-to-apples basis. So all of history has kind of been recasted for Flex and marketing campaigns moving over. So there's no like artificial benefit from that reorganization.

Sure. I get that. I'm more like -- I'm just thinking about before it was moved over, we kind of knew how it was going, and I just don't know if they are -- the reason that is ticking up from an NRR, or would NRR for Communications be picking up more aggressively, and those are more like Segment where they've got below 100% NRR and actually breaking down Communications.

No, I wouldn't say -- I'd say like we'd be roughly in the same position. They're not dragging down. They're not necessarily benefiting the communications business either in terms of pulling up the NRR.
