In this episode of the GMS Podcast, André and Julia sit down with Melanie Müller, Senior Product Manager on the experimentation platform at Booking.com, scientist at heart, and upcoming GMS 2026 speaker.

Together, they dive deep into what it takes to scale experimentation in one of the world’s largest travel platform where testing isn’t just a tactic, but part of the company’s DNA.

What you’ll hear in this episode:

• How Melanie’s journey from physics labs and petri dishes led her to scaling experiments at Booking.com

• The trade-off between speed, quality, and adoption in experimentation and how Booking balances it

• Why stories, not dashboards, often win leadership support for experimentation programs

• The role of community, peer review, and conferences in building a culture of better decisions

• Lessons on evolving from running single A/B tests to building experimentation platforms
