What Luis von Ahn Arellano said

Written from the verified transcript and checked against it. Every figure links to the moment it was said.

Luis von Ahn, CEO of Duolingo, discussed starting the company 15 years ago to provide equal access to education, inspired by his upbringing in Guatemala and the educational disparity he witnessed. He explained that the decision to focus on languages was driven by English's economic value globally. Von Ahn shared that his mother buying him a used computer instead of a Nintendo at age eight led him to learn coding from a book by age nine, setting the foundation for his career. He confirmed inventing CAPTCHA and reCAPTCHA, which was sold to Google, but noted that success comes from hard work and learning from failures through after-action reviews. He outlined Duolingo's freemium model, charging for ad-free and conversational AI features, and highlighted that users are shy about practicing with humans but comfortable with AI. Von Ahn described himself as shy with new people but energized by those he knows well, and outlined company values including 'make it fun' and 'take the long view.' He noted Indonesian learners are highly motivated, with English being the most-learned language, followed by Chinese and Japanese.

Radit 5:07 ↗
And also sometimes we do love to work here as well because you see this amazing view, right? How about the pastries? Can I just like take one out?
Duolingo Employee 5:16 ↗
Absolutely. You are a guest today.
Radit 5:18 ↗
Okay. Sure. You don't want one?
Duolingo Employee 5:20 ↗
Yeah, I had breakfast. You have breakfast, huh?

Duolingo Employee 5:24 ↗

Radit 5:30 ↗

Duolingo Employee 5:33 ↗
Is it like for the for the cups or?
Radit 5:35 ↗
Yes, it is.
Duolingo Employee 5:36 ↗
Okay.
Radit 5:39 ↗
So, what's Duolingo's approach in coming into Indonesian market?
Duolingo Employee 5:42 ↗
We really try to understand the Indonesian audience first, like how they interact online, what maybe lands on them as a joke, what really makes them smile, you know, because we want to make sure that the brand will show up in a way that's truly, truly local and then can put a smile on everyone's face, but then it still keeps like the Duolingo essence. It still sounds unmistakably Duo.
Radit 6:09 ↗
Okay. So you constantly need to get updated on Indonesian trends. Then do you actually keep in touch?
Duolingo Employee 6:17 ↗
Yes, we do a lot of trend-jacking in Indonesia and also we keep up with the trends every day, like what really makes people talk about.
Radit 6:27 ↗
Oh wow. Is there any learning that you get into approaching Indonesian market? Any interesting stuff to share?
Duolingo Employee 6:34 ↗
One thing that I remember is when we entered the Indonesian market, we see that people already make jokes about Duo looking very similar to another brand, Smash.
Radit 6:45 ↗
Oh yeah, I know. I know that one. [laughter] I know which one. Yeah, I know which one.
Duolingo Employee 6:49 ↗
So yeah, I think the jokes are there everywhere. So we just feel like yeah, it's a great chance for us to actually make something about it because people already like it and want to talk about it, right? So why don't we just like champion what people are already talking about and make something fun together.
So yeah, so we did like a great campaign with Icha, and then we leveraged the existing jokes of how similar Duo and then Tapa is, and then put them together in a lot of occasions and it drives a lot of buzz and fun. And I'm glad that you know it because it seems you know like a very viral campaign that...
Radit 7:29 ↗
Yeah, it's very viral. Wow. Looking forward for more Duolingo stuff back in Indonesia.
Duolingo Employee 7:34 ↗
Thank you, Radit. Yes, please enjoy your coffee.
Radit 7:36 ↗
Sure, sure, sure. I'm going to enjoy my coffee, eating the pastries, and going to look around the office.

Okay.
Hi Zan.
Zan Galani 9:07 ↗
Hello.
Radit 9:08 ↗
Can you introduce yourself to my viewers?
Zan Galani 9:10 ↗
Yeah. Hi, I'm Zan Galani. I'm a product director working on video call.
Radit 9:14 ↗
What's your favorite thing about work these days?
Zan Galani 9:18 ↗
Probably my colleagues. I really like working with them.
And I've been at Duolingo 11 years and I'm from Karachi, Pakistan.
Radit 9:26 ↗
11 years. Yes. Oh my. So, you're from the start then?
Zan Galani 9:29 ↗
Pretty much. Yeah, we were just a very small team back then.
Radit 9:33 ↗
How many people back then?
Zan Galani 9:34 ↗
It was 30 people.
Radit 9:36 ↗
30 people. It doesn't look this big in the office.
Zan Galani 9:40 ↗
No, it's like more than a thousand now.
Radit 9:42 ↗
Wow. Okay. What can you tell us about your latest product, video call? Is it?
Zan Galani 9:48 ↗
Yes. Well, number one, it's with more characters now, actually. So, you can talk to Lily, Eddie, Lucy, and Fal. And we've made a few changes recently.
So, first off, the feature, what it is, is it's a conversational AI.
And basically, speaking is like a muscle, right? So, you have to put in the reps. And this is a way that allows you to put in the reps.
Otherwise you can spend a lot of time learning, but when you actually meet someone you know in real life, you freeze and you get a little nervous. Video call allows you to put in those reps to prepare you to be confident with a native speaker when you talk to them.
Radit 10:25 ↗
Oh, sure.
Zan Galani 10:26 ↗
And what we have added recently is, one, you can talk to more characters now. So, people, some people really like talking to Lily, but for others, she's so sarcastic, she's so moody, you know, it's like talking to a cat, you know, and sometimes people want to talk to a dog as well, [laughter] you know.
Radit 10:48 ↗
Free flow chocolate.
Let's go.
Okay.
For free.
Okay.
Hi guys. Hi. Can I join here? Is it okay?
Duolingo Marketing Team 11:53 ↗

Radit 11:54 ↗

Joy 11:58 ↗
Nice to meet you. I'm Joy and I'm...
Kevin 12:00 ↗
Kevin. Kevin.
Evan 12:02 ↗
Evan.
Kevin 12:03 ↗
Kevin as well.
Evan 12:04 ↗
Evan.
Radit 12:04 ↗
Oh, Evan.
Evan 12:05 ↗
Very close.
Radit 12:06 ↗
Okay. Just one letter missing, huh? [laughter]
Ankita 12:09 ↗
Ankita.
Radit 12:09 ↗
Ankita, is it?
Ankita 12:11 ↗
Yes.
Radit 12:11 ↗
Okay. So, which division do you work in?
Ankita 12:14 ↗
Um, we're all in marketing. I'm in influencer marketing.
Radit 12:18 ↗
Influencer marketing. Okay.
Ankita 12:20 ↗
Yeah.
Radit 12:21 ↗
Oh, you should do some influencer marketing in Indonesia.
Ankita 12:24 ↗
I feel like this is it. I only manage the US, but [laughter] um yes. No, I would love to expand. I would love to travel to work with different countries and cultures.
Radit 12:34 ↗
Okay.
Ankita 12:35 ↗
Yes.
Radit 12:35 ↗
So, what can you tell me about working here? How's the working hours here?
Ankita 12:40 ↗
It's 9-5. Oh, yeah. Yeah. It's very varied. Like people from my team, we're not morning people.
So we come here usually around like 10-ish.
And then we leave around like 5 to 6. There are also people who come like, I believe Kevin, you were here like pretty early or maybe like 9-ish.
Kevin 13:01 ↗
Leave when like 5 to 6, like depending on what we need.
Radit 13:04 ↗
So, it's not really strict as long as you finish the work.
Oh, wow. How about the leave days for vacation stuff? How many days can you have for a leave?
Ankita 13:15 ↗
I think first year you have 20 days.
Radit 13:18 ↗
20 days. Yeah. Later you get more, right? Like you have how many years?
Ankita 13:24 ↗
Five years you get more.
Radit 13:25 ↗
You get like two or three more.
Ankita 13:27 ↗
Uh-huh.
They have like a two-week winter break where you basically, with Christmas and New Year's, like you don't even have to worry about taking leave because the whole company is shut down during that time, like a holiday break.
Radit 13:40 ↗
Nobody works during those two because it's like a school.
Ankita 13:43 ↗
Yeah.
Radit 13:43 ↗
Is it a common thing for other companies as well?
Ankita 13:46 ↗
Not at all.
Radit 13:47 ↗
Not always.
Ankita 13:48 ↗
I just started here and when I heard about that I was like shocked because you normally have to like use your vacation days during that time even though everybody else is off. But yeah, this is crazy.
Radit 13:58 ↗
It's really nice.
Ankita 13:59 ↗
It's really crazy.
I started in December. I literally like did my training and then like just like went home early to do like a week remote and I had like the last like three weeks just like free basically. Yeah.
Radit 14:11 ↗
Oh wow.
Ankita 14:12 ↗
It's really nice. How long are you here for?
Radit 14:14 ↗
Don't worry. I'm going back.
Ankita 14:15 ↗
Oh wow.
Radit 14:16 ↗
Wow.
Ankita 14:17 ↗
Are you jet-lagged?
Radit 14:18 ↗
Uh yeah, just a bit.
Ankita 14:20 ↗
Just a bit.
Radit 14:21 ↗
What's the time difference?
Ankita 14:22 ↗
It's 13 hours difference. Well, you should be asleep by now.
Radit 14:27 ↗
Yeah.
Ankita 14:29 ↗
Now you're having lunch.
Radit 14:30 ↗
Yeah, but I got so much coffee like today.
Raccoon dance.
Okay.
Sushi, sushi.
[laughter] Mind game.
[snorts] Can you say PVP? Player versus player in MMORPG game online.
Okay.
Okay.
Strategy.
Oh.
Deal.
Come up. One more.
New Yorkers.
Hello, Luis. Hello.
Thank you for inviting us here. It's been a great pleasure to take a tour of your office and seeing stuff around and taking the chocolate out of the... [laughter]
Luis Von Ahn Arellano 18:21 ↗
Thank you very much for coming. I hope you like the chocolate.
Radit 18:24 ↗
We take so many chocolates. [laughter] And nice view as well. It's good weather today.
Luis Von Ahn Arellano 18:28 ↗
Yes, it's excellent weather.
Radit 18:29 ↗
Yesterday was raining. Yeah.
Okay, let's start with why did you start Duolingo and what kind of problem are you trying to solve with it?
Luis Von Ahn Arellano 18:41 ↗
Yeah. So we started Duolingo about 15 years ago.
Radit 18:45 ↗
Uh-huh.
Luis Von Ahn Arellano 18:46 ↗
I wanted to do something that would give equal access to education to everyone.
I grew up in Guatemala, which is a poor country. It's, you know, right underneath Mexico and it is a poor country. And I was fortunate that when I grew up, I got the education of a rich person even though my family was not rich, but I happened to go to a school that was, you know, for rich kids and it was much better education than everybody else was getting. So I could see the difference between the education that somebody who has a lot of money gets versus somebody who doesn't have very much money.
And that always stuck with me. And then when I came to the United States, what I wanted to do was start a company that would give equal access to education.
Radit 19:32 ↗
Okay.
Luis Von Ahn Arellano 19:32 ↗
We decided that, you know, education is very general. We decided to start with teaching languages and the reason for languages is because in particular English, in most countries in the world, if you know English you can make more money.
And so we decided to make a way to learn English for free. But not just English. If we're going to teach English, may as well also teach other languages. So, you know, that's when, you know, we launched basically an app that would teach many languages, not all languages, but many languages for free. I'm very happy that by now, you know, Duolingo is extremely popular all over the world and that it is used by all kinds of people. So, from children to very old people, and also from, you know, refugees to billionaires. I mean, Duolingo is really used by everybody. So I'm very happy that a lot of people are learning on Duolingo.
Radit 20:24 ↗
Can you tell us more about when you were growing up? What was your favorite subject in school?
Luis Von Ahn Arellano 20:31 ↗
Math. That was my favorite subject.
In fact, I was never very good. I still am never very good at learning languages. I now know multiple languages, but I am not particularly good at it. What I am good at is something like math or physics. That's what I was...
I grew up in Guatemala City. And one of the things that happened and probably the thing that changed my life the most is when I was 8 years old.
Radit 21:02 ↗
Mhm.
Luis Von Ahn Arellano 21:03 ↗
I wanted a Nintendo. I wanted my mother to buy me a Nintendo and she did not buy me a Nintendo. Instead, she bought me a computer, a used computer, and she came back with a used computer and I was very angry because I wanted...
Radit 21:19 ↗
Super Nintendo, right?
Luis Von Ahn Arellano 21:21 ↗
That's exactly what I wanted and I was very angry.
Radit 21:23 ↗
You wanted to play Zelda?
Luis Von Ahn Arellano 21:24 ↗
Yes. I wanted to play Zelda and Mario and all my friends were playing Zelda and Mario, but instead my mom bought me this computer with a keyboard and I didn't know what to do with it.
Radit 21:33 ↗
Okay.
Luis Von Ahn Arellano 21:33 ↗
But I had to learn how to use it and that's, you know, that changed my life in the end. I learned how to use computers at an early age.
Radit 21:40 ↗
Oh. As in you learned to code or...
Luis Von Ahn Arellano 21:42 ↗
I started... basically at first, so this was in the late 1980s. Computers were much harder to use.
Radit 21:50 ↗
Yep.
Luis Von Ahn Arellano 21:51 ↗
So the first thing I just kind of learned how to navigate the computer. But then eventually I started having to learn how to code. I bought a book about how to learn to code and I learned at age maybe nine.
Radit 22:01 ↗
Nine years old.
Luis Von Ahn Arellano 22:02 ↗
Yeah. Yeah.
Radit 22:02 ↗
You learned coding at nine years old?
Luis Von Ahn Arellano 22:03 ↗
I did, which today is not that impressive because they were much younger, but back then that was very impressive.
Radit 22:08 ↗
Wow. That's very impressive.
Luis Von Ahn Arellano 22:09 ↗
Back then, yes. Mhm.
Radit 22:10 ↗
And what did you do with all those?
Luis Von Ahn Arellano 22:12 ↗
I tried to make games for myself because I didn't have a Nintendo.
Radit 22:16 ↗
You didn't get a Nintendo and then you just decided, I want to make my own game.
Luis Von Ahn Arellano 22:20 ↗
Yes. They were not very good.
They were very bad games, but at least I made my own games. Yes.
Radit 22:26 ↗
Well, but the takeaway is you have this constant hunger for learning. I can say...
Luis Von Ahn Arellano 22:31 ↗
I do. I do. I mean, I have two things that are related to Duolingo. I always want to learn more things and the other thing is related to Duolingo.
Most of my life I live with streaks. So for example, the first time I really exercised was about 15 years ago. I have not missed a single day of exercising.
Radit 22:52 ↗
Exercising.
Luis Von Ahn Arellano 22:53 ↗
Exercising in 15 years. Sorry. I have exercised every single day in 15 years. It doesn't look like it, but [laughter] I have not missed a day.
Radit 23:02 ↗
Oh wow.
Luis Von Ahn Arellano 23:03 ↗
Yeah. Yeah. So most everything I do, I'm very constant. I'm a very routine-based person.
Radit 23:08 ↗
So you can say you're a very motivated person. Then...
Luis Von Ahn Arellano 23:11 ↗
It's the opposite. I mean, I end up doing that. But in order to continue doing it, I do things like I keep a personal streak, as in like I just kind of don't allow myself to miss a day.
Radit 23:23 ↗
Okay. Going back to your younger years. So what did you do for hobbies then during those years?
Coding is your hobby?
Luis Von Ahn Arellano 23:31 ↗
Coding. Lego. Lego. Yeah.
Those when I was young. Yeah. Coding and Lego. Those were my main hobbies.
Radit 23:38 ↗
Okay. So I learned that you're actually the one who invented CAPTCHA. Is it?
Luis Von Ahn Arellano 23:44 ↗
Yes. I am sorry. [laughter]
Radit 23:49 ↗
But you actually made reCAPTCHA.
Luis Von Ahn Arellano 23:51 ↗
Yes.
Radit 23:52 ↗
This is true, right? And then you sold it to Google if I remember. You sold to Google.
Luis Von Ahn Arellano 23:57 ↗
Yes. Yes. And I am not sorry for that. [laughter]
Radit 24:01 ↗
It seems like you're in this streak of making successful products. Can you share what is the secret sauce on doing it?
Luis Von Ahn Arellano 24:13 ↗
Many people have asked me what the secret sauce is and I don't think there is one other than working really hard.
Radit 24:19 ↗
Really.
Luis Von Ahn Arellano 24:19 ↗
Yeah. I mean, generally, you know, with Duolingo, we've been working on Duolingo for 15 years. The first few years it was not that big of a success. We just kept on working on it. I think if you work on something that solves a real problem for people, and you work on it really hard, you have a higher likelihood of success. You may still not succeed, but you have a higher likelihood of success. By the way, at Duolingo, we have launched a few things that did not work. So it's not like we succeed at everything we do. We've launched a few things that didn't work.
Radit 24:53 ↗
Okay. So it depends on how you view those failures and then what you can learn from those failures.
Luis Von Ahn Arellano 25:00 ↗
Yeah, learning from failure is really important. I think every time that whenever something does not work at Duolingo, one of the things we do is we have a meeting that's called after-action review where we all sit there and we try to figure out what we can learn from it. What did we do wrong? And if we were to do it again, how would we do it differently?
Radit 25:23 ↗
Okay.
Luis Von Ahn Arellano 25:24 ↗
And that's actually quite valuable. I mean, we've learned a lot from our failures, and that matters a lot.
Radit 25:30 ↗
Okay. Me, I really like free stuff.
Luis Von Ahn Arellano 25:33 ↗
You like free stuff. Okay. I think most people do. I like free stuff, too.
Radit 25:37 ↗
Most people do. I like free stuff, right?
So, what can you share about Duolingo's framework and how to make people who use it for free want to pay for the premium version?
Luis Von Ahn Arellano 25:50 ↗
At the highest level, what we want is that if you use Duolingo and you get value out of it, and you can afford to pay, we want you to pay. So if you can afford to pay and you get value out of it, it is only fair that you pay us because running Duolingo costs hundreds of millions of dollars per year.
Radit 26:12 ↗
Yeah.
Luis Von Ahn Arellano 26:13 ↗
So if it is fair, but if you cannot afford to pay or for some reason have a difficulty in paying, then we actually want you to use it for free. That is at the highest level.
And what we do is basically we offer a very good free product where you can actually learn without having to pay us.
But we do have to offer certain things for those who pay to encourage them to pay.
Radit 26:37 ↗
Mhm.
Luis Von Ahn Arellano 26:38 ↗
In our case, if you pay, you turn off ads. So if you don't pay, you have to see ads.
Radit 26:44 ↗
Yep.
Luis Von Ahn Arellano 26:45 ↗
That's one thing. And then another big one is if you pay, you get conversational practice. And that helps you learn better. And by the way, the reason we charge for the conversational practice is because it's not free for us to give you the conversational practice. It's actually expensive to use the AI to give you conversational practice. So you have to pay.
Radit 27:03 ↗
The conversational practice is video with Lily.
Luis Von Ahn Arellano 27:06 ↗
Yeah, video call with Lily. I mean, if you talk with Zan, he's the product manager for that. He's the leader.
Radit 27:13 ↗
I think it's a very cool innovation.
Luis Von Ahn Arellano 27:14 ↗
It's very cool.
I'm very happy with that. You know, before, we've only had that feature for maybe two years. Before that, we could not get people to practice conversation.
Radit 27:24 ↗
Okay.
Luis Von Ahn Arellano 27:24 ↗
Because the only way we knew how to get people to practice conversation was to pair them with another human.
Radit 27:29 ↗
Uh-huh.
