How Duolingo Aims to Diversify Beyond Language Learning

Launched in 2011, Duolingo grew into the most downloaded education app in the world. Its gamified approach to language learning and use of adaptive AI technology helped it reach 100 million monthly active users and a market capitalization approaching $15 billion by late 2024. The company also saw the potential of Gen AI to power innovative products beyond languages. CTO Severin Hacker envisioned a future in which AI would transform the app into an educational ecosystem, tapping into the $56 billion edtech market. HBS Senior Lecturer Jeffrey Rayport and coauthor Nicole Keller join host Brian Kenny to discuss the case “Duolingo: On a Streak” and the long-term benefits and risks of this diversification strategy.
