Language-learning platform with game-like lessons and AI-powered coaching.
The Story
Duolingo is the world's most popular language-learning platform, designed to make learning a new language fun, free, and accessible for everyone. Founded in 2011 by Luis von Ahn and Severin Hacker, Duolingo has grown into a global community of over 500 million learners across 194 countries. The app offers courses in 40+ languages, from Spanish and French to less commonly taught languages like Welsh, Hawaiian, and Navajo.
Duolingo's gamified approach features bite-sized lessons, streaks, XP points, and competitive leagues that keep learners motivated. The company uses AI and data science to personalize the learning experience, adapt difficulty in real time, and identify where users struggle.
Beyond its core app, Duolingo has expanded into literacy with Duolingo ABC, math with Duolingo Math, and music with Duolingo Music. It went public in 2021 and is now a publicly traded company on the Nasdaq under ticker DUOL, with a mission to develop the best education in the world and make it universally available.
