In this episode of the GMS Podcast, Julia and André sit down with Michael Richter from Robinson Club (TUI) to unpack what truly drives impact: real user insights, disciplined experimentation, and the courage to learn out loud.
What you’ll learn:
How Michael went from “A/B will prove I’m brilliant” to being humbled in three weeks, then building a sustainable experimentation habit.
Why data beats opinions and how to reframe “failure” as learning to shift company culture.
The one-man-team playbook: running ~120 tests across five brands and multiple languages without burning out.
The hotel-lobby insight that led to the “show the unavailable” experiment
Why customer interviews (not gut feel) should seed your best hypotheses.
Confirmation bias, safety nets, and how to get skeptics on board when dev resources are tight.
AI realism: designing for humans who say “I booked service, not self-service.”
