"The project was started at the end of 2009 in Pittsburgh by Carnegie Mellon University professor Luis von Ahn (creator of reCAPTCHA) and his graduate student Severin Hacker, and then developed along with Antonio Navas, Vicki Cheung, Marcel Uekermann, Brendan Meeder, Hector Villafuerte, and Jose Fuentes. Inspiration for Duolingo came from two places. Luis Von Ahn wanted to create another program that served two purposes in one, what he calls a \"twofer\". Duolingo does this by teaching its users a foreign language while having them translate simple phrases in documents. Forbes' staff member Parmy Olson revealed the other incentive towards creating Duolingo. Von Ahn was born in Guatemala and saw how expensive it was for people in his community to learn English. Severin Hacker (born in Zug, Switzerland), co-founder of Duolingo, and Von Ahn believe that \u201Cfree education will really change the world\u201D and wanted to supply the people an outlet to do so. The project was originally sponsored by Luis von Ahn's MacArthur fellowship and a National Science Foundation grant. Additional funding was later received in the form of investments from Union Square Ventures and actor Ashton Kutcher's firm, A-Grade Investments. Duolingo started its private beta on November 30, 2011, and accumulated a waiting list of more than 300,000 users. On June 19, 2012, Duolingo launched for the general public. Due to popular interest, Duolingo has received many investments including a $20 million Series C round of investment led by Kleiner Caufield & Byers and a $45 million Series D round of investment led by Google Capital. Duolingo has 60 staff members, of whom many were Google employees, and operates from an office in the Pittsburgh neighborhood of East Liberty. On November 13, 2012, Duolingo released their iOS app through the iTunes App Store. The application is a free download and is compatible with most iPhone, iPod and iPad devices. On May 29, 2013, Duolingo released their Android app, which was downloaded about a million times in the first three weeks and quickly became the #1 education app in the Google Play store. Duolingo then released both a Google Glass App (glassware) and support for Android Wear."@en . "Indonesian"@en . "Duolingo"@en . ""@en . . "Spanish"@en . "Welsh"@en .
