About Duolingo

Our mission is to develop the best education in the world and make it universally available. Duolingo is the most downloaded education app in the history of the App Store and in 2019 became the top-grossing education app worldwide. We set out to do something altogether different in the learning space. Learning a new language is hard; we believe it should be fun. We use bite-sized lessons that feel like playing a game to keep our learners motivated. Learning a new language can also be expensive, and because we believe it should be free, we made it so. Duolingo has been named to: BuiltIn's Best Places to Work (2023), Fast Company Best Workplaces for Innovators (2022), Fast Company 10 Most Innovative Education Company (2022), among others.
