Chapter 3: What motivated Luis to transition from academia to entrepreneurship?

69.561 - 89.809 Leanna Byrne

Millions use the app every day, but the idea behind it began long before the Green Owl. Luas, you grew up in Guatemala. Education is a huge part of your story. So 15 years ago, you co-founded Duolingo. And today the company's mission is to give people free and high quality education. Now more than 100 million people use it every month.

89.949 - 100.12 Leanna Byrne

And it's a multi-billion dollar public company and a global cultural phenomenon. So Luas Van Allen, chief executive and founder of Duolingo, it's a pleasure to welcome you to Meet the Founders.

100.69 - 101.612 Luis Von Ahn

Thank you for having me here.

102.714 - 106.662 Leanna Byrne

Do you ever just spot people using Duolingo on the street and smile a bit?

Chapter 4: How did the concept of CAPTCHA evolve into reCAPTCHA?

106.682 - 126.805 Luis Von Ahn

All the time. And yeah, I mean, a lot of times I see them in... There's a lot of them in airports preparing for their trip. I look at people's phones to see if it's Duolingo. But I also just hear... Whenever you get an answer right, there's this... The ding sound. I hear it all the time. And sometimes I'm not sure if I actually heard it or if it's just in my mind, but I hear it all the time.

126.825 - 129.909 Leanna Byrne

So you think you're like possibly you're just like paranoid.

0

130.51 - 132.753 Luis Von Ahn

Where is this going on? Yeah, but I do see it quite a bit.

Chapter 5: What led to the founding of Duolingo after selling reCAPTCHA?

133.134 - 141.025 Leanna Byrne

Of course, like you have a target of hitting 100 million daily active users by 2028. How do you even come up with a target like that?

0

141.325 - 154.769 Luis Von Ahn

Well, at the moment, we have north of 50 million daily active users. So every single day, more than 50 million people use Duolingo. But I believe that in the next couple of years, we can double that. And so it was basically doubling where we were at.

0

155.069 - 161.781 Leanna Byrne

Now, you began as an academic solving problems. Do you still feel like you're that academic at heart and you're just trying to solve problems out here?

0

161.98 - 169.671 Luis Von Ahn

Yes, I feel like, I mean, ever since I was about 13 years old, I wanted to become a university professor. I ended up becoming a university professor.

Chapter 6: How did Duolingo's mission change the landscape of language learning?

169.711 - 174.778 Luis Von Ahn

I was one for several years. So I do think that I am an academic at heart.

0

175.019 - 179.365 Leanna Byrne

You grew up in Guatemala City. What were you like as a child? What subjects were you drawn to?

0

179.463 - 194.485 Luis Von Ahn

I liked math. I think that should tell you a lot. I was basically a math nerd. I was very lucky that I had a computer very early. I got a computer when I was age seven because I asked my mother for a Nintendo and somehow she got a better price on a used computer.

0

Chapter 7: What challenges did Luis face as a CEO regarding conflict and decision-making?

194.465 - 209.976 Luis Von Ahn

And she thought it was the same thing. And she gave me that and I had to learn how to use it. So that was, I mean, that made me also a computer nerd. But other than that, I played in the streets a lot with my friends. I mean, this was, these were different times. It was okay to be a child unsupervised in the street.

0

210.192 - 219.107 Leanna Byrne

Yeah. You mentioned your mom, obviously. Yeah, she brought you that computer. But she also, she was a public sector doctor, wasn't she?

0

Chapter 8: What lessons has Luis von Ahn learned about leadership and company culture?

219.167 - 226.48 Leanna Byrne

And she spent most of her money she earned on your education. Did that give you a sense of responsibility that you wanted to make something of yourself?

0

226.578 - 249.206 Luis Von Ahn

It did. So first of all, I was an only child, which is rare in Guatemala. People usually had a lot of kids. So I was an only child, and my mom was a single mother, and she was a doctor, and all her extra money she spent on my education. So what that did is I went to the fanciest school in Guatemala, even though we were not rich. So I went to school with a bunch of rich kids.

0

250.428 - 268.005 Luis Von Ahn

But the people that lived in my neighborhood went to – Usually, you know, either public schools or not as fancy of a school. And it was very clear how much more I was learning than they were. From then on, I remained wanting to do something that would give equal access to education to everybody because I just saw the difference.

0

268.385 - 288.871 Luis Von Ahn

I mean, some of the kids that were living in my neighborhood barely learned how to read and write. I mean, they could read and write, but it was not very good at it. And meanwhile, I was learning, I don't know, whatever, advanced math. So later in life... So what ended up happening is, of course, you know, I went to the US, I've made a lot of money, etc. And these people didn't.

0

289.472 - 296.246 Luis Von Ahn

So I think that's a huge thing. A lot of people talk about education as something that brings equality to different social classes, but I always saw it as the opposite.

296.406 - 303.16 Leanna Byrne

You spoke about Guatemala City and growing up there and that you were able to play on the street, but it was also a time of political upheaval. There was...

303.14 - 324.262 Luis Von Ahn

There was a civil war. There was a civil war going on. Yeah, there was a civil war going on. But fortunately, Guatemala City was pretty isolated from the actual war. The war was more in the countryside. So we just all knew, don't go to these regions. And that's what it was. But if you went to those regions, you probably would get either kidnapped or killed or something.

324.282 - 327.105 Luis Von Ahn

But I just never went there. So I didn't really see much.

327.085 - 329.007 Leanna Byrne

It did affect your family, though, didn't it? Your aunt?
