Duolingo was founded in 2011 by Luis von Ahn, a computer science professor and entrepreneur, and Severin Hacker, his PhD student. The idea emerged from von Ahn’s vision to democratize English learning in non-English-speaking countries, recognizing English proficiency as transformational. This vision expanded to other languages, leading to the creation of a gamified, accessible platform that leverages language science and AI. Early traction came from its unique gamification approach and free access, quickly attracting millions of users and establishing Duolingo as a pioneer in digital language education[3][7].
