Duolingo company history timeline
Duolingo launched its private beta on 30 November 2011, and accumulated a waiting list of more than 300,000 people.
Back at CMU in 2011, he and Swiss-born grad student Severin Hacker (yes, really) focused on an idea the two had been mulling while Von Ahn was at Google, a free digital language-learning tool.
By July 2013, the service has grown to 5 million users and was rated the #1 free education app in the Google Play store.
On 18 February 2014, Duolingo announced that it had raised $20 million from a Series C funding round led by Kleiner Caufield & Byers, with prior investors also participating.
In 2014 he ditched the translation business, and for the next three years the company had no revenue.
On 10 June 2015, Duolingo announced that it had raised $45 million from a Series D funding round led by Google Capital, bringing its total funding to $83.3 million.
In April 2016, it was reported that Duolingo had more than 18 million monthly users.
On 25 July 2017, Duolingo announced that it had raised $25 million in a Series E funding round led by Drive Capital, bringing its total funding to $108.3 million.
In 2017 he introduced Google and Facebook ads, followed by ad-free subscriptions.
On 1 August 2018, Duolingo surpassed 300 million registered users.
Duolingo is on Forbes' 2019 list of Next Billion-Dollar Startups.
On 28 June 2021, Duolingo filed to go public on the NASDAQ exchange under the ticker symbol DUOL.
But TOEFL executive director Srikant Gopal says the correlation is meaningless because the DET has only “rudimentary exercises that bear little resemblance to how English is actually used in academic settings.” Nevertheless, Von Ahn hopes the test will account for 20% of revenue by 2021.
