Duolingo language learning platform

Duolingo is the world's most popular language learning platform, originally developed as a project at Carnegie Mellon University. It was founded by Luis von Ahn and Severin Hacker. The brand revolutionized the education sector by gamifying language acquisition, making it accessible through a freemium model that combines advanced AI with a user-friendly interface.

Based in Pittsburgh, Pennsylvania, the company performs its core software development and research within the United States. Since its launch, Duolingo has grown from a specialized translation tool into a massive digital ecosystem that includes the English Test, math, and music courses, maintaining its status as an independent, publicly traded entity on the NASDAQ stock exchange.
