In this episode of the GMS Podcast, Julia and André dive deep into the world of experimentation with Ton Wesseling - one of the industry’s most respected experts. As the founder of Online Dialogue and the visionary behind Conversion Hotel, Ton has spent decades shaping the way companies approach A/B testing, CRO, and evidence-based decision-making.

Together, they explore:
🔹 The Optimizer’s Disease - why experimenters sometimes can’t stop tweaking and when to let go.
🔹 How to scale from 100 to 1,000+ experiments per year - and why so many companies get stuck.
🔹 The missing link between experimentation teams and top management - and how to gain leadership buy-in.
🔹 Why successful experimentation isn’t just about A/B testing but about fostering a company-wide culture of data-driven decision-making.
🔹 The secret to embedding experimentation in product teams and engineering processes - so it becomes second nature.
🔹 Why some companies thrive with experimentation while others fail - real success stories from the Experimentation Culture Awards.

Ton doesn’t just talk about experimentation - he has seen it all. From high-growth startups to enterprise-level giants, he shares what separates companies that truly scale experimentation from those that stay stuck in the CRO mindset.
