It's the largest e-commerce company in Europe, just behind Amazon.

And it all started with flip flops.

Robert Gentz co-founded Zalando in 2008, after his first startup left him too broke to buy a flight ticket home from Mexico.

With his co-founder, they tested the market with a one-page flip flop shop in Berlin. It worked. So they built a full shoe destination on top of it.

The growth that followed is hard to believe: 6 million euros the first entire year, 160 million in year two, 500 million in year three.

Today Zalando does 20 billion euros in gross merchandise value across 29 countries.

But Europe doesn't make it easy.

Robert learned that the hard way when the TV ad that turned Zalando into a German phenomenon became "the worst ad in the Netherlands" a few months later.

Same continent, completely different reaction.

That's the real story of building at scale in Europe: 29 different markets, 29 different consumer psychologies, and no shortcuts around any of them.

In this episode, Robert reveals:

Why Europe's fragmentation is both Zalando's biggest obstacle and its strongest moat
The real reason free returns increase order value instead of killing margins
Why Zalando builds its own tech stack instead of buying off the shelf
How AI is already rewriting the rules of e-commerce
Why he turned down a US listing and what that says about Europe's future
