The project was originally sponsored by Luis von Ahn's MacArthur fellowship and a National Science Foundation grant.
Hacker (co-founder and current CTO of Duolingo) believed that "free education will really change the world" and wanted to supply people an outlet to do so. A driving motivation was Von Ahn's upbringing in Guatemala, where he saw how expensive it was for people in his community to learn English. Von Ahn had sold his second company, reCAPTCHA, to Google and, with Hacker, wanted to work on something related to education. The idea for Duolingo was initiated at the end of 2009 in Pittsburgh by Carnegie Mellon University professor Luis von Ahn and his Swiss-born post-graduate student Severin Hacker. Duolingo offers a premium service which eliminates advertising and offers more features. The company uses a freemium model with over 500 million registered users. Duolingo also offers the Duolingo English Test certification program and a literacy app for children called Duolingo ABC, and the company released an elementary level math app called Duolingo Math currently exclusive to iOS.
