Duolingo language learning software

Duolingo is the world's most popular language-learning platform, designed to make education free, fun, and accessible to everyone. Founded in Pittsburgh, Pennsylvania, the platform uses gamification to encourage users to practice languages daily. While the product is a digital application, its development and core maintenance primarily take place in the United States and through various global remote engineering hubs.

The company was founded by Luis von Ahn and Severin Hacker. Since its inception, it has grown from a simple translation project into a publicly traded educational powerhouse. Its ownership is distributed among public shareholders following its IPO, though its headquarters and corporate governance remain firmly rooted in the American tech sector.
