I have spent my career watching the retail wars play out across the globe. Usually, when a company hits a massive milestone, it is all over the news. But on April, 2026, something historic happened in complete silence. The REWE Group officially crossed the €100 billion annual revenue threshold.

For those of us in the industry, this is a "wow" moment. To put it in perspective: REWE is now bigger than the global revenue of Carrefour. While the world focuses on Amazon's tech or Lidl's expansion, this German cooperative has built a multi-brand empire across 21 countries without making much noise at all.

How do you build a €100 billion giant that nobody outside Europe has heard of? It comes down to a very specific DNA - a model that chooses local owners over stock market hunters.
