[Operator Instructions] Good afternoon, everyone, and welcome to the Klaviyo Third Quarter Fiscal 2025 Earnings Conference Call. [Operator Instructions] Also, today's call is being recorded. With that, I would like to turn the call over to Andrew Zilli, Vice President of Investor Relations. Please go ahead, sir.

Good afternoon, and thanks for joining Klaviyo's Third Quarter 2025 Earnings Call. Our earnings press release, investor presentation, SEC filings and a replay of today's call can be found on our IR website at investors.klaviyo.com. With me on the call today are Andrew Bialecki, Co-Founder and CEO; and Amanda Whalen, CFO. As a reminder, our commentary today will include non-GAAP measures. Reconciliations to the most directly comparable GAAP measure can be found in today's earnings press release or earnings release supplemental materials, which can be found on our Investor Relations website. Additionally, some of our comments today contain forward-looking statements that are subject to risks, uncertainties and assumptions, which could change. Should any of these risks materialize or should our assumptions prove to be incorrect, actual company results could differ materially from these forward-looking statements. A description of these risks, uncertainties and assumptions and other factors that could affect our financial results are included in our SEC filings, including our most recent annual report on Form 10-K and subsequent quarterly reports on Form 10-Q. Except as required by law, we do not undertake any responsibility to update these forward-looking statements. With that, I'll now turn it over to Andrew.

Thanks, Zilli, and thank you all for joining us today. We had an outstanding third quarter, delivering revenue of $311 million, up 32% year-over-year. These results demonstrate our ability to build products that create more engaging relationships between consumers and businesses, get those products in the hands of businesses around the world and build a high-growth software business at scale. We're now serving more than 183,000 customers in over 100 countries, including more than 6,000 enterprise and mid-market global brands like TailorMade, Mattel, Unilever and Reebok. A few highlights from the last quarter. We delivered another quarter of record net adds in our $50,000-plus ARR customer cohort. We grew revenue in EMEA and APAC by 43% and our Klaviyo service product line, which reached general availability 6 weeks ago, has the fastest adoption rate of any of our products, including text messaging. We're firing on all cylinders and see a lot of opportunity ahead, especially with the addition of Agentic AI to our products. On this note, I'd like to take a few minutes to explain how AI fits in with the products we're building and how it's helping our customers grow faster. The B2C CRM we offer is made up of 3 vertically integrated components: a highly scalable, fast database, restoring everything a business knows about its consumers and making that data available in real time, a set of applications and infrastructure to market, message and serve consumers across every channel and modality and an intelligence layer that finds opportunities to market or serve customers better and can automatically create, deliver and optimize those marketing and service experiences, leveraging the consumer data we have for real-time personalization. AI and LLMs have fundamentally changed and leveled up what is possible in real-time personalization, the intelligence layer and made the entire…

Thanks, Andrew. Q3 was another outstanding quarter for Klaviyo. Demand is strong across every growth engine. AI is amplifying our impact, and we are driving innovation for our customers as the definitive CRM for B2C businesses. Revenue grew 32% year-over-year to $311 million, reflecting robust demand from new customers and continued multiproduct expansion from our existing ones. International revenue growth accelerated for the sixth straight quarter. We had record net adds into our $50,000-plus customer cohort. NRR accelerated to 109% and adoption of our new service product is already outpacing what we saw from SMS at this same stage just 6 weeks after launch. The results are clear. Our growth engines are delivering and AI is a force multiplier. We're investing for high growth while maintaining strong unit economics. Non-GAAP operating margin this quarter was 14.5%, meaning our Rule of 40 performance was nearly 47%, our highest in 4 quarters. There are fewer than 10 public software companies who are growing more than 30%, over $1 billion in revenue run rate and achieving the Rule of 40. We're proud to be among that top-performing group. At our Investor Day, we outlined 3 engines driving Klaviyo's long-term growth: multiproduct expansion, international acceleration and mid-market and enterprise momentum, all fueled by AI, which creates tailwinds for our business and positions Klaviyo to be the platform of choice for brands everywhere. In Q3, each of these engines delivered meaningful progress, which underscores the power of our model. Starting with our multiproduct platform. The foundation of our growth is our large and growing customer base. In the third quarter, we added 7,000 new customers, bringing us to more than 183,000 customers, up 17% year-over-year. Companies are choosing Klaviyo as their B2C CRM because we help them grow their businesses by unifying their customer data,…

[Operator Instructions] And our first question comes from Derrick Wood from TD Cowen.

AB, this is for you. I guess, at your conference, Accenture talked about fatigue in the legacy MarTech market, and there's a lot of desire to change out legacy tech and leverage new AI tech. You talked about seeing a robust replatforming cycle over the next 2 years to 3 years. I know your new products in AI and CRM are still early. But now that you do have these agents in market, are your conversations or pipelines evolving more around replatforming and AI adoption? And I mean, do you see 2026 as a step function and these type of engagements? Or how do you view this cycle playing out?

Yes, sure. So in the mid-market and enterprise segments, we're obviously seeing some really good numbers. We added the most 50,000-plus customers in this past quarter. And I think there's really -- there's 2 things going on that are forcing these conversations. So yes, I do see there's a real acceleration there for 2 reasons. The first is a traditional reason, which is what we're doing by combining the underlying data infrastructure with then the marketing service analysis, application stack and infrastructure, handling things like deliverability on the messaging side, creative design and on the service side, providing that real-time infrastructure can have conversations with consumers wherever they are. I think what's happening on top of that is then when you layer in agents and really here, we mean agents and agentic workflows, we're finding a lot of large enterprises say, look, there's opportunities I can't get to. I can't do this data analysis. There's creative and design that I wish could get checks by agents so we can do more of it. Can you help me find more opportunities to execute against those. And then obviously, on the customer service side, I think a lot of people look at customer service is not just a, hey, when customers have issues, how do I help them? But also how can I proactively give them guidance and look at that as a growth engine. So there was this traditional reason of like, look, my software isn't really talk to each other very well. And now you layer on what LLMs give us in terms of a better logic engine, a better -- smarter way to use the tech that we've built. I think this is the future of how CRM is going to work for consumer companies. It's going to be agentic at its core, which means that instead of the operators of that software having to decide, make every decision, drive the software all on its own, -- it's going to be done in part by agents. And I think increasingly, some of the work they can't get to or don't want to do is going to get handed off. And the fact that Klaviyo provides us like closed loop where, hey, it's not just that we store the data, hey, it's not just that we help you find the ideas and execute them. It's then we can then tell you what's working so you can use machine learning and AI to improve, to optimize over time. That's where this is all going. But I have those conversations with our enterprise customers today and then folks that we're talking to that are in our pipeline, they're very excited about this future. And I think we're in the driver's seat to go deliver for.

Our next question today comes from Samad Samana from Jefferies.

So I wanted to stick on the AI theme. And I know that you guys talked about the Shopify relationship. But I was wondering if you could dig deeper into how the large platforms like OpenAI working more closely with Shopify and giving them access to maybe millions of consumers and how that ultimately benefits Klaviyo as you think about how those could potentially become -- empower the merchants that you're helping and become more profiles, especially given how embedded you are in the Shopify ecosystem. How are you thinking about that in particular?

Yes, for sure. So let's talk -- let me touch on a little bit on the AI ecosystem. Klaviyo, since we started, has been very partner-oriented. We've looked at the ecosystem and how do we plug in, how do we work together to build a better experience for the businesses that we serve, ultimately drive better outcomes for them. So let me touch on a couple of things. First, let's talk about as it relates to commerce and acquiring and building more consumer relationships. Obviously, that's a big part of our business model is we want more businesses connected to more consumers. We think that's an asset that's very important to the businesses we serve. And obviously, that's one of our core monetization axes. So we look at things like the ability to do commerce through products like ChatGPT is great. It's a way for more consumers to find more businesses. It's a more streamlined experience. And ultimately, like we said in the prepared remarks, it results in this like medium- and long-term growth for them because they now have another connection to another consumer. In fact, we're so excited about the idea of like commerce through conversations through chat. It's something we're also working to embed inside of our customer agent. We look at the future, we think that every business is going to have its own customer agent, its own digital, like the best most knowledgeable person about your products, who has all the answers in real time 24/7. We want to build that technology. And obviously, once we answer a question, like, for instance, product [ recommendations ] built in, we want to let consumers then buy directly from that experience. I think in the future, you'll see these agents rather than browse a website, you could…

The next question is Matt VanVliet from Cantor Fitzgerald.

I wonder if you could help us think about the attachment of service already and the fact that it's tracking so far ahead of even some of your best products in history. Are these customers that are replacing something on kind of the legacy marketing stack? Were they doing things sort of haphazardly and this brings it all together? And then maybe more importantly, how is the new product like service helping the conversation of multiproduct expansion, knowing that you can bring it all on a single platform and have that single source of truth?

Yes. I've been really impressed by what our product engineering teams have done for all 3 of our K service, Klaviyo service products in that product line. So let's talk through a little bit about each of them. And just so everybody knows, we put the general availability -- we released the general availability just over a month ago. So we're watching the tracking literally week over week. And like I said, the trajectory is awesome. In terms of what they're replacing or augmenting, let me take it product by product. So for our Customer Hub and customer agent products, those were finding a lot more greenfields. Our Customer Hub product now takes a lot of the personalization that you could do with Klaviyo and messaging on various session channels and now brings it directly into a business's website or even in the future, maybe even their mobile application. It gives consumers a way when they go visit website that the entire web experience is now personalized to them. It's generating incremental revenue, as we talked about. And so it's actually a fairly easy conversation with customers who say, look, we can take the same goodness that you've seen from us in messaging, you can now bring it to your website. It's accretive to your growth. Why wouldn't you do that? A lot of these businesses, they just -- there was no product there before. Integrated into Customer Hub is our customer agents. So if a consumer has a question and they want to chat, both to get help, but also critically to get advice. We're seeing some really amazing conversations inside of our dataset where consumers are coming and having long conversations about what products would be best, best fit for them and offering them recommendations. So really service…

Siti Panigrahi from Mizuho is up next...

That's great. Congrats on a great quarter. And AB, thanks for all that commentary on AI. That's helpful. Amanda, I want to ask you about your '26 guidance of that 21% to 22% growth. So you have a lot of products announcement there and also there are pricing model changes as well. But what gives you that confidence for next year growth? What is embedded into that guidance?

Yes. And the way that I think about it is we are incredibly confident in our growth trajectory. And that preliminary '26 outlook that we gave is a strong baseline for growth next year with clear upside ahead. So we have just launched some very exciting new products in AI and expansion into new products and new service categories. We are very excited about the traction that we're seeing. As AB mentioned, you have service off to an even faster start than SMS was at this stage, but we're really early in the journey. And so at this point, we're not factoring significant revenue in there for next year. So there's even more upside to that number as those products continue to grow. And I think the other thing that gives us incredible confidence heading into next year is that our existing growth engines are really delivering. They have strong momentum as we head into the international or into next year. In international, we saw our sixth straight quarter of increasing revenue growth rates outside of the Americas, which shows that we are really growing and increasing that global opportunity that we have to build the business. In mid-market this quarter, we had a record high number of adds into the 50,000 customer cohort, which really shows what we talked about at Investor Day, which is that customers are pulling us up into that mid-market and enterprise space because as we just talked about earlier with AB, they want to replace those legacy tech stacks and have a more modern AI-driven way for interacting with their consumers. And then in multiproduct, over half of our ARR is coming today from customers who are multiproduct, which shows us that those customers really want to consolidate their platforms and they really want to consolidate their platforms with Klaviyo. So we have a huge opportunity ahead of us there with service. We think service could be as big, if not bigger, than our marketing products are today. And then, of course, AI accelerates all of that. AI makes it faster and easier for our customers to use the product. It opens up new surfaces and new places where we can generate demand and interactions with the product. And importantly, it drives even better results. You heard some of the examples that Andrew shared around marketing agent and the uplift that it's driving in open rates and in KAV or the revenue that our customers drive. So again, those products are early in market. We're already monetizing customer agent today. We're going to start pricing pilots for marketing agent in the next few months. And as they continue to grow and expand in adoption and usage, again, we see upside there. So bottom line is that what gives us confidence is that our growth engines are firing on all cylinders, and we're in the early innings of massive AI and multiproduct opportunities that are ahead of us.

The next question is from Tyler Radke, Citi.

A lot of great discussions around AI and Service Hub. I wanted to double-click on international, pretty impressive subsequent consecutive quarters of accelerating growth. Do you think that acceleration could continue going forward? And could you just help us understand like what we're going to -- what we should expect in terms of future unlocks in that? I know you talked about adding new languages to the platform, expanding text message capability, but sort of what inning of sort of those product unlocks are we? And any view on sort of the durability of that acceleration?

That's great. I'll give you some commentary on some of the things we're doing, and I'll let Amanda speak to -- the numbers. But 43% year-on-year growth. We're very proud of that, and we believe that we can continue to have that grow at very high rates over the next several years. And let me give you a little color on why. What we found is we're still relatively early in working in both Europe, and I'd say Europe is even a little bit further ahead than where we are in Asia. There's a lot that we've done in the last 12 months, 24 months to get us ready for that. We've expanded our presence in Europe and in Asia and continue to do so, especially in like key markets. From a product side, we've done a lot of work. You did mentioned internationalization -- very proud of the work that we've done there, both for our products, but also then to just make the various channels that we're in more available. So having SMS now in so many languages obviously helps a lot. We just rolled out WhatsApp globally, and that's obviously very, very important in the European and Asian markets. And we have some more channels now that will be coming online following that, that are more region-specific. So it addresses more of the places that where consumers and businesses meet. And then finally, we're expanding our presence, not just for our customer teams and go-to-market teams, but also just our infrastructure. We already have infrastructure all the way around the world. We're setting up new data centers and planning those out in both Europe and in Asia. And I think that will also help, especially for some of our larger customers. So will overlap with some of our enterprise strategy. So just very excited. We've got a great set of customers. We're also expanding the weight of the partners that we have there in key markets. So I think we've got a long way to go. We're nowhere near saturated.

Yes. And in terms of what helps drive that consistency in growth going forward and our outlook in international, it's the product expansion that AB talked about. And it's also the progress that we have on the go-to-market side around building out all of the surround sound around those product innovations. It's getting the local partner network set up, both agency partners and the platform partners as well, great platform partners, not only Shopify, who we have an incredibly strong relationship with, but partners like PrestaShop in France and Shopware in Germany and then also continuing to build out the customer experience, including the website, the local customer case studies. And so all of that contributes to making this a really strong, consistent growth platform for us going forward.

The next question comes from Rob Oliver from Baird.

I think at the Analyst Day, you guys called out, I think it was over 600 legacy replacements in the last couple of years. And there's been a few questions, [ Garek's ], and one other that have tried to touch on, I think, this opportunity, which is, I think, so exciting for many of us, which is that this combination of service, marketing and commerce has actually been tried before and there's buying there. And so maybe you can talk about as we look into the next year and the next couple of years, the pipeline you have building right now, some of the customer examples you called out, the fashion brand, 7-figure renewal, how should we think about that opportunity increasing over that kind of 600 number over the last couple of years?

Great. We don't have any numbers to share today, but the momentum is awesome. And similar to international, I think there's things we're doing now that have -- that we'll finish doing that will now bear even more fruit. So as an example, we've only recently spun off our Analyst Relations program. We're now starting to work with more SIs and global system integrators, which is introducing us to more large enterprises. I think, obviously, enterprise and international go hand in hand. We've already worked with a number of large multinationals, but that will get only better as we do some of the work that we talked about on the international side. And look, the bedrock of this for us is, I think, really the 2 things I said. The first is since the beginning, this idea of your data infrastructure should have a tight linkage to how you do marketing messaging, the infrastructure there and then now what we're doing with service, customers love the idea -- the enterprise actually love this idea of one database now with -- that's getting more intelligent via LLMs and AI that is then distributing that experience to all possible channels. This really, really matters to them that they want this one unified experience. So this idea that like you can use the data you have at scale to generate things like recommendations and then make those available on all services, websites, mobile apps, messaging inside of a chat or in a voice conversation with the customer, all delivered via AI. That's a really enticing value prop. And so I think that there's just -- there's a lot we're doing now that the results we're seeing are a little bit of the actions that we've taken in the last 12 months, 24 months. But I think there's even more that we can do. And frankly, like there's even an element of social proof to all of this. I talked to businesses that said, hey, 12 months, 24 months ago, they didn't think of Klaviyo as an enterprise brand that we are quickly changing that perception, and I expect to see that snowball.

Ryan MacWilliams from Wells Fargo has the next question.

Great to see continued strong new customer additions. This question is more in regards to your customers. So we're hearing SEO struggles come up more for SMB. And I was wondering, are you seeing customers look to Klaviyo as a way to support new market activities to combat SEO efficiency getting more challenging? Or are you seeing existing customers look to add new use cases as a result?

Yes, it's a great question. So I'll say 2 things. We look at Klaviyo as really as the bedrock of how a business operates and works with maintains and grows its engagement with its most important asset, its customers. those end consumers. So we're noticing actually like 2 trends. The first is for some businesses, they're seeing a lot of growth through AEO and effectively like getting discovered through some of the AI applications that are out there. And so that's driving more consumer relationships. For other businesses, we find them -- they're actually -- when it's uncertain what their strategy is, they're coming back to Klaviyo to say, "Hey, how can I do more with my existing consumer relationships? How can I nurture those harder? And this is where AI really plays in. I mean one of the things we want to deliver them is like, look, we automatically, agentically give every single business for every single one of their consumers a path on like what is the absolute best experience they can deliver to that consumer. So when they do acquire them that those consumer relationships are more valuable, more durable, higher LTV. So it's a bit bifurcated, but I think when there's uncertainty and revenue is really on the blind, we find people come back to us. Just as an example of that, we're about to enter the holiday season. We find that for most of our businesses we work with, especially in retail, this is when they see the highest percentage of return consumers coming to their business. They know the consumers when they're shopping for the holidays come back to businesses they already know. And that's why you see so much more incremental usage of Klaviyo. And we're excited actually to have all these -- some of the AI functionality we've delivered now help them do a better job connecting those customers to the exact right product or the exact right service in the most critical time of the year for them.

The next question is from Scott Berg, Needham & Company.

Really nice quarter here. I guess one question for me is we've been to a lot of sales and marketing conferences in the last month or 2. And we're seeing a ton of customer interest in the space, but budgets tend to be just a little bit light right now. And your commentary suggests that there should be a lot of expansion of budgets on some of this newer AI functionality as we get into the new calendar year. Does that track with what you all are seeing today? Or are you seeing customers more emphatically kind of spend on some of this functionality here even in the third or fourth quarters?

Yes. Let me make 2 comments on that because I think it's probably a bit of a clarification too, like how we think about our role in the awareness buying process, what we think of like the marketing and sales cycle. So the first is every product that Klaviyo builds -- at its core, we make sure that like it needs to show its ROI, there needs to be revenue directly attributable back to that product. I think that's the case that not a lot of sales and marketing products can make. Oftentimes, there are tools that you might have a sales team use or a marketing team use. And it's not only like its productivity to that person, but you can't -- you might be able to measure the hours saved, but you can't see the dollars that, that product is generating. And I guess the second point is like, so what's the difference between how we build products for marketing, for sales for revenue generation versus a lot of what's out there in the market. And this is why we started to attach to this word agentic. I think there's a big difference between AI products that sort of assist a person doing a job. That's great, and we should want those products. But ultimately, they're just kind of -- they're not doing the work for you. They're just helping you do the work. What we found with a lot of the AI applications inside of Klaviyo. And if you look at what, for instance, our marketing agent is doing, the goal is to help -- assist a little bit, but it's really doing the job that we find the business we work with, they don't have the time or maybe the skills to get done or maybe…

Up next is Arjun Bhatia from William Blair.

I just had a couple of quick ones. First, Amanda, I think you mentioned you're going to start running sort of pricing pilots for marketing agent coming up here. Can you just maybe touch a little bit on what that might look like and what you're starting to experiment with? And then second, we're heading into Q4, important holiday season, as you pointed out, just would love to get your sense on how you think that's shaping up relative to last year?

Sure. So on marketing agent, we're seeing great results. We talked about on the call some of the outstanding results that our customers are seeing in terms of improvements in open rates, improvements in the KAV that they're generating per campaign. It's really helping amplify the work that they were doing and enable them to do more work at higher quality in less time. So there's a lot of excitement about it and generating a lot of value. And so we're going to start experimenting over the next couple of months with what does that look like in terms of a pricing pilot of how do we monetize it. Some of it, we're going to continue to build into the product natively, the things that we think are really important for all brands to have access to. And a great example of that is some of the image work that we talked about on our last quarterly call. But again, in those places where customers are really seeing that incremental value, we're working on how do we charge it. And we've got great confidence in that because of the results that we're seeing from some of our other areas where we're already using AI in the product, right? So we're live right now with customer agents and customers are seeing great results from that, and it's driving paid revenue. And then we're also seeing great results from marketing analytics, which incorporates a lot of AI-driven insights and analytics into helping our customers better target. So examples we've had recently are customers -- one customer who's using marketing analytics and its predictive gender feature, which is an AI-enabled feature to predict the gender of a given consumer and better target the campaigns that get sent to them, which is helping them…

And our final question today comes from Terry Tillman, Truist Securities.

This is Connor Passarella on for Terry. I want to follow up on the previous commentary on the holiday season and specifically how that relates to service product adoption. Just for the 3 service products, there's introductory promotional pricing through December 31. Is there typically interest from the customer base to committing to these new -- or to new products during the holiday period of Q4? Or do you kind of often have customers that just want to focus on executing into the end of the year?

Yes. It's a good question. So among the 3 Klaviyo service products in that product line, it's a little -- we're seeing some differential in behavior. So let me just walk through them. So the first is for our Customer Hub product. We've made the integration onto our customers' websites, into their stack so seamless, like literally just a few clicks, and it's already leveraging and trained on all of the data inside of a Klaviyo account. We're finding a lot of customers want to adopt that even up leading into the holiday season because they know it will drive incremental revenue. So we're seeing really good uptake there. I think similarly, where you find where customers that have not used a customer agent and AI that can automatically resolve conversations or help guide consumers. There are some folks that want to test that out and have larger deployments, but we're also seeing really good uptake there. And I'd say maybe for larger -- and then finally, for our help desk, that sometimes depending on the size of the team can be more of a bigger build of, hey, I up the learning new system. We've already -- we had a lot of conversations with folks say like, "Hey, this is great. Just talk to me later in December, early January, once I get through the holiday rush. So that product might be a little bit -- that may be delayed a few months. But in general, actually, one of the things I'm really excited about is if you think about we launched all these products at the end of September, there's a lot of companies that would say, hey, our technology stack is set for the end of the year. And already, we're seeing really good growth in a…

Once again, everyone, that does conclude today's conference. We would like to thank you all for your participation today. You may now disconnect.
