206. Challenges and Opportunities for Language Apps with Tobias Dickmeis from Tandem

In this episode, Jan sits down with Tobias, co-founder of Tandem, to unpack the story behind one of the world’s biggest language exchange apps and what it takes to build a sustainable product in a crowded market. Tobias shares how Tandem grew from an early video chat concept into a global community with tens of millions of users, why the business needed capital to reach critical mass, and how the team has navigated the trade-offs between growth, monetization, retention, and user experience. Jan also opens up about the journey behind Teacher AI, from YouTube and online courses to building a product-first business around speaking practice, and the two compare notes on what really drives growth today. They discuss the shift from creator-led distribution to product-led value, the rise of partnerships, the limits of paid acquisition, and why schools, LLMs, and word of mouth are becoming increasingly important channels.The episode closes with a lively game of “Would you do it?” where Tobias pitches a series of language app ideas and Jan gives his honest verdict on what feels like a feature, a side project, or a truly exciting new company.
