Duolingo Isn't a Language App. It's a Slot Machine.

In 2020, Duolingo's own researchers explained how the app picks your nightly reminder by asking readers to imagine a room full of slot machines. That system helped turn a free language app into a company worth more than $544 a share, and it was built on streaks, leagues and loss aversion. Then the same machine was pointed at revenue, and the stock lost roughly 80 percent. #Duolingo #BusinessDocumentary #RiseAndRuin
