EP7 - Unicorn Files - Wallapop: The Flea Market That Revolutionized Used Goods

Barcelona, 2013. Three friends observe overflowing attics and closets full of unused items and ask themselves: 'Why not transform the neighborhood flea market into a geolocation app?'. Wallapop is born, a mobile-first platform with over 19 million users in Spain, Italy and Portugal.

In this episode we analyze Wallapop's journey: from the initial insight into local second-hand, to the 2016 merger with Letgo to compete with OLX at a global scale, to the return to geographic focus that saved the model. Wallapop's story is a case study in what happens when a marketplace startup tries to do everything and then learns to do one thing well.

What makes Wallapop interesting is not just the product, but the strategy: geolocation as a trust lever between strangers, community as a barrier to entry against generalist competitors, and the ability to monetize progressively (shipping, promotions, services) without touching the DNA of the free product. You'll learn why the Letgo merger failed, how Wallapop reclaimed the Iberian market, and what are the mechanics of a C2C marketplace that works long-term. An unmissable episode for anyone building a two-sided platform. You'll also discover key signals for understanding when a marketplace should stop expanding geographically and return to dominating the territory where it has already won.
