Duolingo language learning app

Duolingo is a world-renowned educational technology brand founded by Luis von Ahn and Severin Hacker. Originally conceptualized at Carnegie Mellon University in Pittsburgh, Pennsylvania, the platform has grown from an academic project into the world's most popular language-learning application. The brand is famous for its gamified approach to education and its green owl mascot, Duo.

As a digital product, its 'manufacturing' or development primarily takes place at the company's headquarters in the United States, though it serves a global audience in over 40 languages. The company transitioned from a private entity to a publicly traded company on the NASDAQ in 2021, maintaining its independence and head office in Pittsburgh. Today, Duolingo, Inc. remains the ultimate owner of the brand, continuing to lead the market in mobile-first education through its suite of apps, including Duolingo, Duolingo ABC, and the Duolingo English Test.
