With this recent funding, Duolingo’s total funding amounts to $83 million – following a $20 million Series C round last year – and raises the company’s valuation to nearly half a billion dollars. Despite Sturdy’s excitement for the company, this is pretty significant news considering that Duolingo hasn’t exactly done a great job of monetizing its app. As The Wall Street Journal reports, the company has made some revenue in the past from CNN and others who worked with Duolingo to have some content translated by users, but that method of monetization wasn’t sustainable. Duolingo is currently the most downloaded app in the Education category on both Google Play and Apple iTunes. Through its game-like language education approach, users from across the world can learn more than 40 languages, including even fantasy languages like Klingon. The app now has more than 100 million users from across the world. According to Duolingo cofounder and CEO Luis von Ahn, there’s a high barrier to access when it comes to human tutors – they’re often scarce and cost a lot of money. With this recent funding from Google Capital, Duolingo wants to help schools and governments develop their language courses using Duolingo’s platform. Through an initiative called Duolingo for Schools, classrooms can utilize a specialized version of Duolingo’s popular language-learning app to help teachers track each student’s progress. Thus far, the initiative has seen more than 100,000 teachers register.
