In 2011, two professors from Carnegie Mellon University, Luis von Ahn and Severin Hacker, had a simple idea: make language learning fun and accessible.
They wanted to create an app that felt like a game, making it easy for anyone to learn a new language. That’s how Duolingo was born.
But it wasn’t an instant success.
Duolingo started small, and the team faced many challenges.
Early users found the app too difficult and frustrating.
Instead of sticking to their original plan, the team listened to feedback and made changes. They simplified the lessons and made the app more intuitive.
