Scaling a global marketplace to 7 Business Units and 42.5 million offers takes more than technical patches, it demands a complete team realignment. In this talk, we share our 2025/2026 “Test & Learn” journey: a period of relentless exploration that led to our biggest breakthroughs. Our key insight? Scaling a marketplace isn’t just about code, it’s about people and processes. By investing in the “unsexy” parts of the product, we uncovered hidden gems of optimization. We’ll walk you through our multi-axis approach to tackling the reality of scale, built on three pillars: technical stabilization, organizational clarity, and product value. This isn’t the story of a magic fix. It’s a deep dive into a mindset shift - “Performance is a feature” - and how it transformed the way we publish millions of offers.
