In 2011, after spending a couple of years working at Google, I decided that I wanted to dedicate myself to helping to transform education. I was particularly inspired by my upbringing in Guatemala, a poor country where high-quality educational opportunities are limited to those who have money.

I usually make to-do lists with timelines, and pen and paper does the trick for me.

It's hard to think of a time when I'm not working, but when that is the case, I like to travel and eat good food.

I watch a lot of TV. That's how I spend most of my time outside of work. If I had more time, I would fill it 100 percent with watching TV.

One fact we're particularly proud of is that there are more people learning languages on Duolingo in the US than there are people learning languages in the entire US public school system.

Because education is such a broad area, I chose to focus on language learning.
