Duolingo (NASDAQ:DUOL) is a leading digital education platform that specializes in language learning through a mobile app and web-based interface. Founded in 2011 by computer scientists Luis von Ahn and Severin Hacker, the company has grown from its initial beta launch to become one of the most downloaded education apps worldwide. Duolingo’s core mission is to make education free, fun and accessible, leveraging gamification techniques and adaptive algorithms to engage users at every proficiency level.
The company’s flagship product is its gamified language courses, which cover more than 40 languages, from widely spoken options such as Spanish and French to niche offerings like Welsh and Hawaiian. In addition to its core courses, Duolingo has expanded into assessment with the Duolingo English Test, an online, on-demand certification accepted by institutions around the globe. The platform’s user experience emphasizes bite-sized lessons, interactive exercises and a reward-based system designed to foster daily practice and long-term retention.
Duolingo serves a global audience, with significant user bases in North America, Europe, Latin America and Asia. The company’s content and interface support across various devices ensures accessibility in both urban and remote regions, helping to bridge educational gaps where traditional language instruction may be limited. Strategic partnerships with schools, universities and nonprofits further extend Duolingo’s reach, integrating its courses into classroom curricula and workforce training programs.
Headquartered in Pittsburgh, Pennsylvania, Duolingo is led by co-founder and CEO Luis von Ahn, who brings a background in computer science and entrepreneurship, including pioneering work in crowdsourcing technologies. Under his guidance, the leadership team has focused on product innovation, data-driven personalization and expanding monetization through subscription services and certification offerings. As Duolingo continues to refine its platform, it remains committed to its founding ethos of democratizing learning on a global scale.
