Duolingo, the popular language lesson app, makes up from $400,000 to $600,000 day, according to founder Luis Von Ahn. Von Ahn was recently on the NPR’s podcast, How I Built This, and talked about the foundings of his company and his previous company, RECAPTCHA.
Von Ahn says there has been an uptick of usualbility during the pandemic with people who want to learn another language during the lockdown. He first noticed it in China and then it follow that same trend across the world.
Duolingo uses the freemium model; the app and the website are accessible without charge, although Duolingo also offers a premium service for a fee.
