The slow and steady rise of Babbel has been impressive on many fronts. The company is now managing the top-grossing language learning app in the world. That’s why I’m excited to announce that we’ll have founder and CEO Markus Witte as well as CEO U.S. Julie Hansen at TechCrunch Disrupt Berlin.

Babbel has been around for over a decade. The company started with a web-based language learning service. It was based on Adobe Flash and HTML. Now, most Babbel users interact with the service using the company’s mobile app.
