DUOL - NASDAQ

Good evening, everyone, and welcome to Duolingo's Third Quarter 2024 Earnings Webcast. Today after market close, we released this quarter's shareholder letter, a copy of which you can find on our IR website at investors.duolingo.com. On today's call, we have Luis von Ahn, our Co-Founder and CEO; and Matt Skaruppa, our CFO. We'll begin with some brief remarks before taking questions. Please note that this evening's event is being recorded and all attendees are in listen-only mode. A quick reminder that we'll make some forward-looking statements regarding future events and financial performance, which are subject to material risks and uncertainties. Some of these are outlined in the risk factors of our filings with the SEC. These forward-looking statements are based on assumptions that we believe to be reasonable as of today, and we have no obligation to update these statements as a result of new information or future events. Additionally, we'll present both GAAP and non-GAAP measures on today's call. These non-GAAP measures are not intended to be considered in isolation from, a substitute for, or superior to our GAAP results, and we encourage you to consider all measures when analyzing our performance. And now, I will turn it over to Lily.

Thanks, Debbie, I guess? Hi, everyone. So Luis asked me to cover for him. Lucky me. Anyway, let's just get this over with. How did we do this quarter? Pretty good, I'd say. We did way better than expected in all the important metrics. Since we did so well and we feel good about next quarter, we're raising our full year guidance. Matt's going to get into the details in a minute. He's into that kind of thing. And yes, we're hitting our goals. Daily active users, up 54% year-over-year, which, okay, is pretty neat, especially since users accelerated last year. Family Plan has grown to 21% of subs compared to the 18% we had at the end of last year. Oh, and our new Duolingo Max feature video call lets learners chat with me. Lucky them. Don't worry, I won't judge, much. Maybe just an eye roll here and there. How did we pull this off? You know the usual stuff, product improvements and social marketing. It just works. And the grand finale, generative AI and automation, yes, that's the future, I guess. I mean, look at me, an animated character running this call. AI is going to help us be more efficient and launch products faster. Pretty cool, right? So we're investing in that stuff. Anyway, I'm done. Over to Matt. He'll probably try to sound more excited.

Thanks, Lily. I'll do my best. Now, you may be wondering why we had Lily step in for Luis. Well, we wanted to give an example of how generative AI is positively impacting more and more aspects of our business. We're using it to make product more fun, engaging, and effective through features like video call with Lily. And we're using it to automate internal processes like content creation. By the way, that video only took about seven minutes to create because of the tools and the infrastructure that we put in place. Now on to the numbers. As Lily highlighted, Q3 was a strong quarter. DAU grew by 54% year-over-year, which is impressive considering we're lapping last year's 60%-plus growth. Bookings and revenue grew 38% and 40% year-over-year, respectively, which came even as we lapped tougher comps. And we posted an adjusted EBITDA margin of 24.7%. This quarter's performance was driven in part by the strength we're seeing in Duolingo Max. As a reminder, Max is our highest subscription tier and now includes our new AI-powered video call feature. We executed well and rolled out Max faster than we expected. Max is now available to roughly half of our DAU, and we expect this will increase by about 10 points or so, as we scale it to more users, primarily on Android by the end of the year. We also saw early signs of strong demand for video call with Lily. We find that when we introduce new features, we see a one-time bookings gain that eventually settle down into a more predictable run rate. Some of the Max bookings increase this quarter was likely driven by this type of effect. Looking ahead, we're raising full year guidance. We're guiding to bookings and revenue growth of about 36% and 40%, respectively, for the full year. And our Q4 guide takes into account video call's estimated impact and our experiments around our New Year's promotion. Our Q4 guide has about 100 basis points of sequential quarter-over-quarter decline in gross margin, which is due to higher gen AI and amortization costs related to scaling Max and its video call feature. As a reminder, our Duolingo Max tier yields more gross profit dollars, but a lower gross margin percentage than our Super tier. We're also raising our 2024 adjusted EBITDA margin guidance to 25.5% at the midpoint, which is roughly 8 points higher than 2023. As we continue to make progress towards our long-term target range of 30% to 35% adjusted EBITDA. For Q4, our adjusted EBITDA guide of 24.4% at the midpoint reflects quarter-over-quarter operating leverage of about 70 basis points for R&D, 90 basis points for S&M, and that's offset by some slight deleverage in G&A. We ended Q3 with approximately 49.6 million fully diluted shares outstanding using the quarter end close price. And we expect net dilution of a little more than 1%, similar to last year. Ah, and good timing. It looks like Luis is back.

Thanks, Matt. I'm glad Lily was able to cover for me. Now let's take some questions and Debbie will manage the queue.

All right. Sounds good. If you have a question, you can use the raise hand feature. So your first question comes from Justin Patterson at KeyBanc.

All right. Thank you. And Luis, since you subbed in with Lily, I will sub in with baby Luca here, who's just out for his walk and nap right now. Nothing puts him to sleep faster than earnings calls. But if I project from your current trends and think about how next year or even 2026 goes, you're probably crossing 10 million subs within about an eight to nine-year period since you started monetizing. So as you think ahead, what does it really take for you to add the next 10 million, reach 20 million subs? Is that just expanding price tiers? Is that more marketing, new apps monetizing? Would love to hear about how you're thinking about that philosophically? Thank you.

Yes, it's a great question. I mean, generally, we're going to continue doing what we've been doing because it's working really well. And in terms of monetization, there's a few things that we're doing. First, we're growing the number of users, just this is paying and nonpaying users. As we grow that, we grow number of subs because a certain fraction of them subscribe. We're going to be doing everything that we do for that, that is making the product more engaging, also doing our social marketing. So that should increase number of users. And as you saw, our DAUs are growing, been growing between 50% and 60% really for the last two years. So there's that. And then we're just going to get better at converting these users. And there's a number of things that we can do. For one, we're going to have our bread-and-butter stuff that just basically makes improvements to our purchase page or when we give the offer to the users to subscribe. But also the new plan, Max. We think that there's a lot of geographies where Max is going to be more interesting than Super. And in particular, for English learners, they're very interested in practicing conversation, which is what we offer with Max, the video call feature with Lily. So, we think there's going to be a lot of subscribers coming from that. But generally, that's kind of the philosophy for it.

All right. Justin, thank you. And we're going to go to the next question, which is Ryan from Needham & Co.

Congrats on a great quarter. Thanks for taking the question. Maybe just on the -- in the shareholder letter, Luis, you talked about sort of 2 million DAUs now that are learning sort of using the platform for intermediate English learning or higher. Obviously, you talked about sort of this initiative of driving more English learners to the platform. I think it was about six months ago now. Can you just give us a sense of on that 2 million, sort of, what sort of progress has been made within that last six months since you've been focused on it? And maybe what regions you're seeing sort of or languages you're seeing sort of the most attractive pickup or most near-term pick up on usage? Thanks.

Yes. Thank you for that question, Ryan. So, as we have been saying, English learners are a pretty major opportunity for us. The reason for that is because if you look at the broader language learning market outside of Duolingo, the majority of the spend, about 80% of it is from people who are learning English. But if you look at Duolingo, the amount of revenue that we make from people who are learning English is significantly less than 50%, so there's a major opportunity there. And the reason that we are underrepresented within the English learners is because we haven't historically had intermediate or advanced content in English. We started working on that a few years ago. And by now, all of that content is there so we're very happy with the content. We're obviously going to continue improving it because we're always improving everything, but the content is at least there. The other thing that we've done is we've worked a lot on placing users. English is a unique language in that because it's the lingua franca for the whole world and because in most countries, people learn some amount of English in schools, they -- mostly when they come to the app, they have some previous knowledge unlike most other languages where usually when they come to the app, they're beginners. So, we have to really do a good job of placing users in the right place. And we've been working on that quite a bit. And at this point, we feel pretty good on the product in terms of the content and then also the placing. So, that feels pretty good and we're going to continue seeing growth like we said in the letter. We have over 2 million daily active users in English in advanced or intermediate content. We think that's growing pretty fast. And now one thing to call out here is that most of our growth comes from word of mouth. I mean, we're going to be doing some marketing to get the word out, et cetera, but most of our growth comes from word of word of mouth. Now, mouth growth is excellent in that it's very cheap. We don't have to pay for it, people just tell their friends. But it's also not super-fast. So, we expect that because historically, there just hasn't -- people haven't really thought that Duolingo has intermediate or advanced English, we expect that it's going to take a couple of years for really the word to get around that our English courses are good for intermediate and advanced speakers. So, that's kind of what's going to happen, but we're very excited and that’s pretty major opportunity.

Maybe as a follow-up, it seems like as you continue to roll out new functionality, that you're maybe starting or expanding to the Android user base maybe a little bit more quickly than you have in the past. Just curious how the uptake on Android users has been for the new functionality. And if you're seeing any differences in terms of how those users are converting relative to maybe in the past couple of years? Thanks.

Yes. I mean, we do -- the way we develop, usually, we put features first on iPhones and then on Android phones, where we usually, call it, three to six months behind an Android. And we're getting better at that. It's getting faster and faster. Right now, we are working on, for example, adding all the Max features to Android. That's something that we're adding. One of the things to mention is that we expect -- usually, by the way, Android users just don't monetize as well as iPhone users. That's just -- that's industry-wide. This is just not Duolingo, it usually is the case that they probably have lower purchasing power. But one thing that is interesting is we are seeing in in our Max features and particular, the key Max feature of video call, we're seeing that English learners are using it about twice as much as people who are learning other languages. So, we expect, because Android, in particular, has more English learners than iPhone, we expect that there's going to be a really good uptake there.

Excellent. Thanks for taking my questions.

Thank you.

Okay. Next question comes from Aaron Kessler at Seaport Research.

Great. Thanks guys. A couple of questions. Maybe just as a follow-up on the intermediate English learning. Can you just go through kind of maybe the marketing strategy to engage the users or make them aware of that? And then second, I think last quarter, you mentioned pretty strong international growth, including Japan with benefiting from kind of more country managers. Just any updates on some of that international growth this quarter as well? Thank you.

Yes, thank you. So, we do a very specific type of marketing. You've seen our social media, it's pretty unhinged. That type of marketing, our bread-and-butter marketing is not particularly applicable to convincing people that we have intermediate English content, right? I mean, the owl breaking things and doing dances is not really applicable. What we do think is applicable is having influencers. We do have -- we use influencers in a lot of countries, and so we're going to be doing that. It actually works pretty well. And not just us doing the marketing. For example, there's videos that people do, without us even paying, that do this very well. For example, there was a video recently that got a lot of views like many, many millions of views of a guy who just used Duolingo to learn for a few months and then just went to Russia. And he just recorded himself trying to do stuff, and it turned out that he was able to do it. That type of stuff is really good for efficacy because it's like, you can go to Russia and actually get around. So that's the type of stuff we're going to be leaning in on our marketing. And in terms of -- okay, so 1 last thing I'll say about the marketing, which is I'll reiterate what I said in the previous answer. That's what we're going to do for the marketing. But once again, the main way in which we expect that word to get around that we have the intermediate and advanced content is through word of mouth because that has worked so well for us. So that's probably going to be the main way. So there's that. Then for your second question in terms of international growth, we're very happy with the results so far for international growth. If you ask about our DAU growth right now, this quarter, we reported 54%. It's broad range. So, every single country is growing well. Of course, some countries are growing a little more than others. But it's -- basically every region is growing. We have country marketing managers on a number of countries. We're about to add new ones. We're about to add Italy and Turkey. And we have ones in Korea, in Japan, in China, in Brazil, et cetera. We have a lot of them and that works really well. And typically what it is, is we hire 1 or 2 individuals there in country, and then they help with our basically localizing our humor and our kind of TikTok and YouTube accounts. And so far, every single country where we've applied this, it has worked.

Great. Thank you.

Okay. Next question comes from Ralph Schackart at William Blair.

Good afternoon. Thanks for taking the question. Luis, maybe just get an update on the macro. Some investors might see this business model sort of fairly discretionary, and you're growing 50-plus percent in DAU. So maybe just sort of riff a little bit, if you can, on why you think the model has held up so well and why you think can continue to grow at these growth rates. And I'll ask Matt a question since he's kind of quiet over there next.

I mean, in general, we see a lot of opportunities still to grow in most -- we're -- the number of people who are learning a language in the world is about 2 billion. We have about 100 million monthly active users, so there's a lot of runway in there. And so we're just going to continue growing. I mean, by the way, like we've said last time, we expect our DAU growth for the rest of the year, certainly, to be around 50%. So we're going to continue strong growth. And like I said, for the last 2 years, it's been 50% to 60% year-on-year, so we just expect that to continue happening. Over the longer term, we expect other subjects to start helping, too. So this is language learning, but we expect that math and music are going to start contributing more and more over the next few years. So we just -- we feel pretty good about macro in that respect.

Yes. And Ralph, before you ask me a question, the addition I'd add to Luis is just that our entry-level price for Duolingo is free, so that helps. And then the actual subscription is just not very expensive on a monthly basis, even Super or Max.

Great. And then just maybe, Matt, on margins. Just kind of remind us of your framework for letting the business scale versus reinvestment opportunities. Obviously, the model's scaling pretty significantly. You've thrown off a lot of cash and margin, but how do you think about incremental margins going forward?

No, it's a great question and it gives me a chance just to kind of highlight the fact that we have scaled incredibly well. I mean, at the top line bookings CAGR over the last 3 years is 42%, including our most recent guide. While we've done that 8 quarters ago, we had $2 million in Q4 of adjusted EBITDA, and we just guided to $49.7 million at the midpoint. It's 25x on adjusted EBITDA. So it feels like we're scaling both growth and profitability really nicely, and we're doing that with your point around incremental margins above our long-term target of 30% to 35%, and we think that, that's reasonable. But first and foremost, we feel like there's a ton of opportunity. The first question was how do you get to 20 million subscribers. We've had -- you had a question about macro, you got questions about DAU growth. There's lots of opportunities and lots of ways to win. So we're going to continue to invest, first, back into R&D because that is our primary way to grow, through word of mouth. So I think it's a yes, and Ralph, we're going to continue to try to invest for growth, but we're going to continue to scale profitably as well.

Awesome. Thanks, Luis. Thanks, Matt.

Great. Thanks, Ralph. Next question comes from Bryan Smilek of JPMorgan.

Great. Thanks for taking the questions. I guess just to start on Max available to 50% of DAUs, up from 15% last quarter. Can you just help us understand the conversion cycle of a Max subscriber from when it becomes available to -- when they go down the funnel? And I guess like how does that differ versus Super?

So there's a couple of things to say. We've -- yes, we've been increasing Max. The way we've been increasing Max, by the way, is by adding it to more countries and in more courses. At this point, we're around 50% of our daily active users have access to it. Now that doesn't mean they bought it, but they have access to buy it. By the end of the year, it will be somewhere between 60% and 70%. One important thing to say about that, by the way, is that we're adding countries, but the countries at this point is mainly long tail that's left. All the kind of wealthy countries, we've added. Now in terms of how the funnel is, we're seeing a lot of people who are buying Max the first time they subscribe to anything. So they're not -- they're a free user and just they go directly to Max. And we're also seeing a bunch of people who were Super subscribers who were able to upgrade to Max. So we're seeing both of these. And it's a bit early to know exactly where this is going to settle because some of the features in Max are very new, particularly the feature of late that has really unlocked a lot of purchases in math, the kind of the key feature is video call with Lily. And that feature has only been around for two months. So I don't really know exactly what's going to happen, but I get a sense that this is going to vary geographically. So there will be some countries like the US, I'm guessing, that where Super is going to be the main package because it's a package for convenience, whereas there will be some countries, particularly the English learning ones, that that -- where it could be Max is the main package because this is not -- usually in the poor countries, people don't pay for convenience but they do pay for things like learning how to converse better. And so there may be some cases, some countries where actually we'll have more Max packages than Super packages. We just don't know exactly how it's going to be yet, but that's kind of what I think will happen.

Awesome. Thank you. And I guess, one more, if I could, just on DAU growth. As we go into 2025, can you just walk us through the building blocks of DAU growth? I mean, coming off strong growth in the 50%, I mean, where do you think realistically the TAM expansion is going to come from? Will it be more English in 2025 or are we still talking more non-English learning?

I think we're going to see growth from all regions. I mean, the nice thing about our growth so far is that, really, there is no country where we are growing very slowly. It's just they're all kind of growing pretty fast. Where we're going to see next year, I think we're going to continue seeing growth in our more penetrated markets like the US. And I think we're going to be layering a lot more English growth. So it's kind of -- it's going to be both. And again, the reason that that we believe we can continue growing fast is that we really are just scratching the market for language learning. I mean, there's 2 billion people learning. And in addition to that, not only is the 2 billion people learning, in some countries, we are completely growing the market. I mean, for example, in the United States, about 80% of our users are people who were not market before. They weren't learning a language. So we just don't see that anything is -- there's nothing that we that is pointing us to some like cap or anything like that.

Thank you, both.

Thanks, Bryan.

Thank you, Bryan.

Next question comes from Ross Sandler at Barclays.

Great. So I guess it's kind of a question for both of you guys. But Luis, you were on the Decoder podcast recently. Nice job, by the way. And I think you had said that, at the subscriber level, that Max is accretive to margin. And Matt, you just mentioned that COGS is going to go up because of the video call feature, which makes sense. But could you guys just make sure we got those right, just unit economics versus overall cost? And then I guess, more importantly, Luis, inference costs are down like 90% in AI right now. And so as that gets cheaper and cheaper in subsequent years, how does that potentially change either the Max rollout or feature rollout, more things like the video call with Lily, et cetera? How are you thinking about that broadly?

Yes, let me answer your second question first, and then I'll let Matt answer the first question. So yes, costs will continue going down. That's our expectation. And not only is cost going to continue going down because large language models are going to be cheaper to query, it's also the case that we ourselves have not spent a lot of time optimizing costs. I mean, the directive that all our teams have is don't worry too much about cost at the moment for large language models because that's going to naturally go down. So just develop the best features you can, and over time, we're going to -- if we see that, that maybe the LLMs are not going down in cost all that much or something, we're going to start optimizing ourselves. So we really do believe that cost will go down. What that will do is it will allow us to offer things like video call with Lily in -- at more reasonable prices for certain countries. We think that the price is good for a country like the United States. We don't think that the price at moment -- I mean, we don't even have it in India, but at some point, we're going to have it in India. We probably, at the moment, cannot offer it for that attractive of a price. But I think sometime next year, the price will be pretty attractive. So it will just allow us to offer it to people in poor countries. Now the thing about people in poor countries, those are exactly the ones that want to learn English. And the people who want to learn English are exactly the ones who want to more so practice their conversation. So we think this is going to be a pretty major unlock, the decrease in price.

Yes. And just to follow-up on the first part, Ross. We launched Max because we had a belief that there was a demand for Duolingo at higher price. And Gen AI enabled us to add features to that tier that allowed us to charge that price. And for example, like Luis said, in the US, it's roughly 2x the price of Super. So when you have that 2x of price, you have plenty of gross profit dollars to play with. And so that's -- when Luis was on the podcast, we definitely make more gross profit dollars per subscriber for Max than Super. The margin -- the gross margin percentage is lower because in addition to the app store fees, there's a set of LLM calls. But for free cash flow and adjusted EBITDA dollars, we're making more. And so we still feel good about it. The point that Luis was making on cost also applies to price. We have charged the team with just making a wonderful product. And you saw an example of that on the -- or something like that on the beginning of this call. We still haven't optimized all the way pricing and costs. And so we'll do that over time and that will help margins as well.

Yes. The good news is we're running -- the number of tests that we're running per quarter is increasing, so we are running more tests per quarter. The success rate for the test is about the same. And it's actually a funny thing, it's about almost exactly 50%. So every test that we run has about a 50% chance of succeeding. And by succeeding, I mean that it did what we wanted it to do, like it increased whatever metric we wanted it to do to increase. So the pace of test is increasing, and we feel pretty good about the number of things that we have coming up over next -- we have visibility, I visibility for about six months. We feel pretty good about the things that we have for the next six months in terms of number of tests.

Yeah. And Andrew, the other thing I would add is just that the teams do run experiments like from time to time to try to enable it themselves, to speed up their own experimental frequency, to get data faster, to analyze the experiments more rapidly. And so we're always running trying to run those. We're going to run some this quarter, for example. So we think things can speed up.

That's helpful. And then if I think about a similar question within the framework of what is recently launched products, so if I think about adventures and video calls, can you guys maybe benchmark that as a surface area for testing versus what is streaks or maybe the leader board in terms of past products that have been successful in terms of driving, again, curve? Thanks so much guys.

I guess, maybe it's taking a step back a little bit. The way we operate for the Duolingo app is we have a number of different areas that cover basically the main things we want to improve. And there's three main things we want to improve. We want to monetize better. We want to make it more engaging, and we want to teach better. And depending on what the feature is related to that area is going to be working on, so for example, the streak is something that makes the app more engaging. And we are running -- and we have run I don't know how many experiments on the streak, hundreds, possibly thousands, and we have way more that are coming up in the next several months. Features like adventure and video call, these are usually -- the main goal of those is to teach better so they're being run from the areas that have to do with teaching better. And they're going to continue running a bunch of experiments. And the last thing that I'll say is the number of people that we have working on each one of these kind of engagement, teaching better and monetization is roughly the same. So we have about equal number of people working on each one of them.

Okay. Next question comes from Curtis Nagle at BofA.

Great. Thank you so much for taking the question. I guess, first one, maybe just focusing on the family plan, it ticked up a little bit, I think you said 21% of subs. I guess, in terms of the contribution of some of the new product features you've added versus -- or maybe in addition to trying to increase visibility of the product, what's been the contribution of those two? And where do you think this tier can evolve in terms of total mix, let's just say, over the next 12 months?

So we've done two things for the family plan, and you're right. One is we've made the family plan better as in we've added features to it or fixed some things that weren't exactly bugs where like kids under 13, the parents couldn't see their name. Now they can. So we've done stuff like that and then we've also made it more visible. The majority of the contribution is actually making it more visible. The features are good and that will probably help over the long-term in terms of the retention of the family plan, but just generally making it more visible is what has had the most contribution. In terms of what exactly the penetration will be over the next year, it's very hard to say. I mean, I honestly just don't know the answer to that. I expect it to continue going up but I just don't know at what speed.

Got it. Okay. And then just the follow-up. I don't think we touched -- maybe it was in the third letter, I missed it, but the resurrected user, which was a focus for last quarter, making some progress and you're focusing there. So in terms of however you want to measure it, whether it's subs or DAUs, the contribution in 3Q relative to 2Q, how did that look?

Yeah. Resurrected users are a pretty big opportunity for us. What's happening as time goes on, the way we look at top of funnel is basically either users that are coming in brand new to the app or users that are coming back after a long hiatus. That's top of funnel. So one is new users, the other one is resurrected users. Obviously, when you just launch an app, all of your users are new users because you're brand new. As time goes on, a higher and higher fraction of your users that are from the top of the funnel are resurrected users. At this point, we have gotten to the point where more than half of the top of funnel is resurrected users. So there are -- on a given day, a larger number of users are coming back to the app after a long hiatus than new users. And that's just natural for a product. Of course, this also varies per geography depending on how penetrated this is the case. I mean, in the United States, where we've been operating for longer, there's a higher fraction of resurrected users versus in a country like maybe India, where we just haven't been operating for that long. This is a pretty major opportunity for us because we just haven't worked too much on the experience of when people come back. So we feel pretty good about that, and that's going to be a good area of growth. The other thing that I should mention about resurrected users is a thing that is important for people to understand. A lot of times, when people think about these subscription models, they think, well, after a user has left, they'll never come back. That is just not the case with Duolingo. I mean with Duolingo, it is rare to see that a user leaves and never comes back. Usually, when they stop using Duolingo, they usually come back. I don't know exactly how long it will take them, but three months later, two years later, et cetera. That's a pretty common thing. And interestingly, this is just an interesting tidbit. The most common answer when you ask users why they stop using Duolingo is I haven't stopped, which is a funny thing. They still see themselves as Duolingo users, even though they may not have been around for 35 days or 40 days.

Appreciate the comments. Thanks.

Our next question comes from Wyatt Swanson at D.A. Davidson.

Hey, guys. Thank you for the question. Could you discuss maybe what you're seeing in terms of overall subscriber retention? Just like any changes in retention trends as you roll out additional features? And then are you seeing any differences in subscriber retention for Super Plan versus Max?

No, I appreciate the question. The overall retention hasn't changed since we last talked about it last quarter or the quarter before. blended retention on the platform is pretty stable at this point. That could change over time. We don't actually have enough data yet on Max at scale to really know how that's going to retain. We have enough data that makes us feel like comfortable that the LTV will be superior to super. But we don't know exactly where that's going to stabilize, just like we don't know where the top line run rate will stabilize. So we're watching it, and we'll let you all know how it's trending. But so far, there's been no major changes on the platform and retention.

Okay. Next question comes from Arvind Ramnani at Piper Sandler.

By the way, really good animation. Yes, Luis, I really like listening to you but this was -- Lily -- I enjoyed her.

You know what, she's doing part of my job now. Over time, she's going to do more and more of my job and I can just retire.

Yes. The core part of her job and at least sort of like I was just very enjoyable to say that probably one of the most enjoyable earnings calls that I had in several quarters.

Good.

Yes. Just quite a question on DAUs, right? I mean, I think it's a big focus for investors, and I think like we have talked about in the past, like long-term, should we be comfortable as long as DAUs is, at some point, higher than revenue growth? That's like a more normalized way to think about it. Because the last two years, we've talked about extensively, there was a lot of unusual factors that got it to like really, really kind of impressive level. But like longer-term, how should we think about the relationship with revenue growth and DAUs?

I don't know exactly how to answer that question. I mean, my sense is for the last -- it really has been a little over two years where every single quarter, our DAU growth is somewhere between 50% to 60%. Now this obviously won't last forever. I mean, we are saying for the rest of the year, at least it will be 50%. It won't last forever. But my sense is that we are going to continue seeing strong DAU growth for a while just because the main way in which we grow is word of mouth and also adding more features to the -- or improving our features. And we just have a really good set of improvements planned. So I think that will be the case for a while. I don't know what steady state will be. And I don't even know what that steady state means. But I don't know if, Matt, you have anything about that. I'm not sure how to answer that question.

Yes. No, I don't have the perfect ratio, Arvind. But I do think just give me a chance to remind everyone that we have not just several ways that we can grow users. So Luis has already talked about new to the platform, resurrected users or users has been away from the platform for a month coming back. There's many levers we have to grow users. And then there's many experiments, hundreds of experiments every quarter where we grow conversion from free to paid. And then there's experiments and vectors that we have to retain subscribers better, and then there's mix shift between plans and then there's pricing. And I won't bore you, but I would just say that there's a lot of vectors throughout the funnel from free user to retained paid subscriber that give me confidence that we can sustain really nice revenue growth above 25%, say, in a lot of different DAU environments. Now I agree with Luis. We have a bunch of belief that we'll be able to grow users nicely for some time. But I think there's a ton of lever. So yes, that's why we feel comfortable that our revenue growth rate should stay strong for a long time.

Yes, perfect. And I just have one follow-up question. Certainly, your Duocon, Consumer Day was really enjoyable. But we really don't get -- I mean, investment company, we really don't have any insight of like, how does one compare to the other, right? I mean, we're looking at from a product and so are there any kind of metrics or anecdotes you can share from this year's like kind of Consumer Day versus Duocon this year versus last year? Any incremental like from a metrics or anecdotes.

For Duocon, in particular?

Yes.

The number of live views on Duocon was three times the number of live views from last year. There's all kinds of ways to measure them because, by the way, live views is one thing, but we also get to see a lot of views over the next week, over the next month, et cetera. But it's generally, really every single year, we're just getting a significantly higher number of both live views and also historical views for each Duocon. And I think it just has to do with the fact that our brand is more well known.

Perfect. Just if I can slip one last one in. When you think of Duolingo Max and Super, I think what other things has been like what product or features go into one versus the other? They will have -- is it still like the way because line? Or do you have a kind of what goes into each? And then of course, you have Max, right, like which is another thing.

Yes. I mean, I can tell you where we're at, at the moment. I cannot guarantee that we'll be there three months from now because things change here fast. At the moment, where we're at is Super Duolingo has the features that basically where you pay for convenience, for example, turning off ads or unlimited lives, like unlimited hearts. That's paying for convenience. Max, the more time passes, the more in my head and in our product team's head is basically video call with Lily. We have other features in there but by a wide margin, at this moment, video call with Lily is the killer feature for Max. And what -- if you think about that, what that is, is just practice conversation. So at the moment, the way I'm thinking of Super versus Max is Super, you pay for convenience; Max, you pay for getting better conversation. And that's it. That's, at the moment. Again, maybe when we talk in three months, I'll tell you something completely different.

Perfect. Thank you so much.

All right. Next question comes from Alex Sklar of Raymond James.

Great. Thank you. Luis, I kind of want to follow up on that video call conversation. What has the early data told you so far? I mean, you had a trial period. Now the limited launch in terms of usage. And I'm curious if there's been any notable uptick in terms of like growing time per session or better street retention that, that might translate to higher Max retention or greater adoption longer term? Thanks.

Yes. The usage metrics for video call are very good. And the -- what I really like is that they match our expectations. And by that, I mean, English learners use it more than non-English learners because they're more interested in conversation. Also for any language, more advanced users use it than less advanced users. And it's exactly what we want. And we're seeing -- we're making changes to the experience. We're trying to make it more engaging, for example. You saw the video that we played at the beginning of this call. Lily has a lot of different kind of facial expressions, et cetera. We're adding more and more and more of those to make it more realistic. And every time we do we do that, it becomes more engaging and are seeing that. So we see increases in the number of calls that we'll have or the amount of time that they're spending with it whenever we make it more realistic or the conversation topics are better. The other thing is we're going to be getting a lot better with the actual conversation topics. For example, right now, Lily lives in a world that where, for example, news doesn't really happen today. What should have happened today is Lily should have talked about -- if you call her, she should have talked about the election. But that's not something that is currently happening. But in a few months, that's how it's going to be. So we're feeling pretty good about that. Hopefully, I think that answers your question.

Yes. No, great color there. Matt, maybe just a follow-up for you, but you referenced in the prepared remarks, still a little over a month away. Any changes to how you're planning on approaching holiday kind of New Year season from a promotional standpoint this year, given you'll have a wider Max rollout and any different kind of timing assumptions that are embedded in your outlook? Thanks.

Yes. No, the outlook is always a bit uncertain around the fact that we launch our one promo of the year and it has four days in December and then obviously, the month of January. So that's the same as it's been in years past. We do run experiments every year to service things differently, to promote it in different ways, and we'll start running those -- we usually run them in early December and then launch them. Those are a bit tougher to predict. So, that's -- but that's all incorporated into the guidance.

Great. Thank you, both.

And our next question comes from Shweta Khajuria at Wolfe Research.

Thanks Debbie. Thanks for taking my questions. I guess I'll try two, please. One is on international markets. If you talked about France and Korea, in last quarter, you had mentioned those two as adding marketing managers post your success in Japan. So, how is that tracking? And have you added more international countries with marketing managers? That's question one. And then the second question is on your marketing strategy. If you're seeing anything, if you could comment on the pricing that you're seeing on social media platforms, how have ROIs trended for you? Anything in particular that you're seeing over the past quarter and in this quarter-to-date? Thank you.

Okay, great. So, international markets, yes. We very recently added marketing managers for France and Korea. And France is a little longer, maybe a few months and Korea is really like weeks. So, it's too early to say in Korea. France is looking very good. It's just, again, every time that we follow the playbook, it ends up working. It may take a little longer in some countries than others, but it ends up working after a few months. And we are already seeing it working in France. We are about to add also, like I mentioned, Italy and Turkey. So we're going to be doing that. And we have a few others that we're considering adding for next year. In terms of marketing strategy, you said things like social media prices, et cetera, we don't pay for the vast majority of our social media stuff. I mean, we do a little bit of performance marketing, but the social media that we're known for, where like our TikTok videos or our YouTube Shorts, et cetera, that is all organic. We don't pay for that. So, the cost of each one of those videos is the cost to make it and the majority of them, it's like a couple of hundred dollars to make it. And that's it. We do a little bit of performance marketing but it's kind of small enough that, that's not affecting us, whether -- it doesn't really affect too much, whether the prices are going up or down. I'm sure there's an effect, but it's just not something that I personally track.

Thank you.

Okay. Next question comes from Mark Mahaney at Evercore.

Okay. Thank you. Could I run a couple of questions by you? The growth of the U.S. market is kind of as your oldest most mature market in terms of bookings or revenue or MAUs or DAUs, is that still pretty consistent with that of the global growth rate? That's question one. Secondly, I'm sorry if you covered it early on. Have you said anything about what kind of traction you're actually seeing for Max? I know you talked about what percentage of the user base has access to it now, but did you provide any disclosure at all and what kind of traction you're seeing for it? And then third, I just want to ask about an ARPU question. And Matt, I know there's a lot of moving pieces in that kind of average bookings per average sub. But one of those factors is this greater adoption of Super and Max. Are those big enough now to kind of sustainably cause ARPU to grow going forwards? Thanks a lot.

Let me take the first two, and then Matt will take. Matt answers anything with acronyms. Okay. So the US market, yes, growth in the US market is good. It is growing similar to most countries. Again, it's not the case that the US is the fastest growing country but it's also not the slowest country. And it's also not the case that we have huge disparity between countries. Most countries are kind of growing at similar rates and it's a similar rate to our overall average. So the US is somewhere, I don't know exactly where it is, but at roughly average. So we feel pretty good about the US growth. In terms of Max traction, yes, we feel very good about Max traction. And in particular, the reason we feel very good about it is, because over the last couple of months, we added this extra feature, which is video call with Lily, and that is really allowing us to advertising Max in a much better way, because what happens with video call with Lily, the previous Max features that we had explained my answer and role play were a little hard to understand for users. But this one is so easy to understand. Within two seconds, people get the ideas like you can get to talk to Lily. And you just say that and we're like, Oh, well, yes, I want that. And so we're seeing really good traction in terms of people actually buying Max. I don't think we released the precise numbers just yet but we feel good about it. And then Matt, you want to talk about ARPU?

Yes, Mark, so I'm talking about ARPU, so not -- it's actually revenue, not bookings on this part of the conversation. But as you can see in the numbers, our ARPU trended towards 0% year-over-year, which we've talked about for the past couple of quarters about getting it to flattish, I think, was a word I used. And it's now, I guess, technically flattish. It's 0% year-over-year. And we do think it can go a bit higher. The things that impact ARPU for us are basically what you said, there are planned mix. So is it Super or Family historically has changed the pricing with family plan obviously, being higher ARPU. And then going forward, Max will definitely impact that given it's 2x the price. Right now, Max is not of the scale that is really showing up materially in the ARPU mix right now, again, because revenue is amortized over 12 months. And so we've only really seen a material impact in the past quarter. So, I expect that to come through. And then the other things that change ARPU are foreign currencies, regional country mix. So I think going forward from a -- we'll update you all on how family plan Super and Max are trending on ARPU. But right now, we feel good about the trend. It's gone from negative year-over-year growth to 0% this quarter and probably can stay there or go a little bit higher.

Okay. Thank you, Matt. Thank you, Luis.

Thanks Mark. We have two more questions to get through in eight minutes. We've got Chris Kuntarich from UBS.

Great. Thanks for taking the question. Maybe just another one here on Max. I think you talked about seeing more engagement with conversations with Lily from English speakers versus not like, I guess, it's English versus not, which puts us at kind of a 50-50 dynamic where kind of thinking about who's actually adopting the Max sub at this point? Should we be thinking about it as roughly evenly split at this point? Or are we talking about English being more closer to 2:1, 3:1 sort of adoption of Max at this point? Or any sort of color you can provide to help frame that would be helpful.

Yes. I'll maybe put some takes on this. Max is significantly more expensive than Super. In the US, for example, it's twice the price. So, you would expect that wealthier countries are adopting Max more, and that is -- there's some push there. On the other hand, the main feature for Max is video call with Lily, which we are seeing that English learners, which predominantly are in poor countries, use that twice as much when they have access to it. So that would give a push towards English learners/poorer countries adopting Max. So there's this push and pull on either side. I don't know where it's going to settle because, for example, right now, Max is not available in some very large English learning countries, like it's not available in India, for example. So we're going to put it there and that will happen over time. So I don't know where it's going to settle. At the moment, there are more Max users in wealthy countries. So they are usually the ones that are not learning English. But that, I think, is going to change. I don't know if it's going to be -- I just don't know where it will settle, but it's -- that's going to change some.

Got it. And maybe just -- I noticed the call out that there was a meaningful contribution from Max to total bookings in 3Q. I don't believe that was in the 2Q press release here. Any sort of kind of framework to be thinking about there? Like should we be thinking about that now as over a low single-digit sort of growth contribution within the quarter?

Yes. I mean, I think that, that's why we called it out was Q3 was really the change in terms of Max materiality. And then as I called out in the Q4 guide, the Q4 guide does incorporate what we believe will happen with Max in video call in Q4. So it is now a meaningful part of the guide and our performance. We don't -- again, I think that we're still in the initial stages of this, especially with video call. So in Q3, I referenced the fact that, that led to like some onetime bumps as we rolled it out more broadly. I think we'll probably see some of that in Q4 as well. But yes, I think that's all incorporated in the guide.

Got it. And just a clarification from earlier. Did you say whether or not we should be expecting it with the New Year's discount offering?

Yes, we're going to run experiments on it. So -- but you'll just have to show up in the last four days of the year and figure it out.

I'll be there. Thank you guys.

Okay. And our final question comes from Crystal Li at CMS.

Okay. Thank you management for taking my questions. And very honored to be the final one asking questions. So I'm just wondering how's your view on the paying ratio trend for Duolingo Max in longer-term. Do you think it will exceed that of the Super Duolingo plan? And could you share more view on the competition landscape on the AI video core products? Thank you.

Yes. It's -- we don't really know where it will settle, whether it will be a higher fraction of people doing Max versus Super. I think it will depend on the country and our relative prices to them. So it's very hard to say where this will end. Now in terms of competition, generally, we -- what's gets us to stand out, what gets us to be the category leader in language learning is a number of things. I mean, first of all, we have understood that the hardest thing about learning something by ourselves or learning a language by ourselves is staying motivated. So everything we do tries to keep you engaged. I mean, the app is very gamified. For example, also our conversation feature, you don't talk to a random character. You talk to Lily and Lily starts becoming your friend, et cetera. So we really try to make everything we do engaging. And that's something that really makes us stand out. The other big thing that makes us stand out is our freemium model where really the vast majority of our users use Duolingo for free, because our free tier is very good. Now that does a lot of things. For one, it gives us a very large scale. And having such a large scale allows us to collect data to teach better and also to make Duolingo more engaging. So we just have a lot more data than anybody in history about how people learn languages. And the other thing that the free tier does is that it's acts as our marketing engine. The reason we can be so efficient with marketing, I mean, we really spend very little on marketing compared to most apps of any kind. And the reason that we can do that is because our free users basically act as our marketing engine. They tell their friends. And so that's what we think differentiates us from competition. Yes. Thank you.

Okay. Thank you. That’s very helpful.

Okay. Well, that's it for questions. I'll turn it back to Luis to wrap it up.
