It launched to the general public on June 19, 2012, at which point the waiting list had grown to around 500,000. Duolingo launched a private beta on November 27, 2011, and accumulated a waiting list of more than 300,000 people. In October 2011, Duolingo announced that it had raised $3.3 million from a Series A round of funding, led by Union Square Ventures, with participation from author Tim Ferriss and actor Ashton Kutcher's investing firm A-Grade Investments. An early revenue stream, a crowdsourced translation service, was replaced by a Duolingo English Test certification program, advertising, and subscription. The founders considered creating Duolingo as a nonprofit organization but Von Ahn judged this model unsustainable. The project was originally sponsored by 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 with 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. Its optional premium service, Super Duolingo, is ad-free and has more features. The company uses a freemium model, with over 500 million registered users. It also offers the Duolingo English Test certification program Duolingo ABC, a literacy app for children and Duolingo Math, an elementary-level math app (currently only for iOS). It offers courses on over 40 languages, from popular languages such as English and Spanish to less commonly studied languages such as Welsh, Irish and Swahili.
