About Duolingo

Duolingo is the world’s most popular way to learn languages online with over 120 million users. Founded in 2011 by crowdsourcing pioneer Luis von Ahn and Severin Hacker, it is the most downloaded Education app on iOS and Android and has been awarded Apple's iPhone App of the Year and Android's Best of the Best.

With the mission to bring ‘free language education to the world, we’re building a future in which the highest-quality education is accessible to all. Our approach is simple — language learning should be fun, personalized, and based on science.

Duolingo has raised US $83.3 million to date from investors including Union Square Ventures, New Enterprise Associates, Kleiner Perkins Caufield & Byers, and most recently, Google Capital.

There are over 1.2 billion people learning a language and the majority are doing so to gain access to better opportunities. Unfortunately, learning a language is expensive and inaccessible to most.

We created Duolingo so that everyone could have a chance. Free language education – no hidden fees, no premium content, just free.

Duolingo is used by the richest man in the world and many Hollywood stars, and at the same time by public schools students in developing countries. We believe true equality is when spending more can't buy you a better education.

Everyone learns in different ways. For the first time in history, we can analyze how millions of people learn at once to create the most effective educational system possible and tailor it to each student.

Our ultimate goal is to give everyone access to a private tutor experience through technology.
