What happens when one of the most trusted voices in experimentation sits down for a deeply honest conversation about growth, culture, learning, and unlearning?
Today, Julia and André talk with Kevin Anderson, curator of Experimental Mind, creator of Experimentation Jobs, and longtime experimentation leader at ING and Vista.

This is not just a conversation about A/B tests, it’s a conversation about how people, teams, and organizations learn and why experimentation is really a mindset we’re all born with.

Highlights:

• Why “data looks back but experiments look forward” and how experimenting generates new data instead of analyzing the past.

• The hidden cultural blockers that stop companies from becoming experimentation-driven and how to work with (not against) them.

• What kids teach us about experimentation: why we lose our natural experimental mindset as adults, and how to get it back.

• How experimentation reduces debates & politics by transforming opinions into testable hypotheses.

• The power of listening tours when entering a new company culture and how to “unlearn” your previous playbook.

• Building an experimentation career: Kevin’s path from analytics, to product, to fractional PM, to entrepreneur.

• How community accelerates growth and why conferences are actually “group therapy” for experimenters.

• Join us live at GMS 2026 in Frankfurt on June 16th, 2026 and connect with 700+ optimizers, experimenters, and growth professionals from around the world.

Are you still unsure what to make of AI?
Does it feel more like a threat than a tool?
You’re not alone and this episode will change the way you think about it.

In this new episode of the GMS Podcast, we take you on a playful yet deeply insightful journey into the world of AI adoption.
Starting from a place of fear and overwhelm, we explore how to turn AI into an advantage without losing your human superpowers.

Together we dive into:

• The 4 levels of AI adoption from Level 0 (fear and resistance) through the “wooden sword” stage of experimenting, all the way to the “steel sword” and beyond.

• How to overcome fear with curiosity and why “just try it” can be the first step toward new possibilities.

• Real-world use cases: how AI cut research analysis time in half without replacing the need for human insight.

• What AI can’t do (yet): the critical gaps where human empathy, context, and reading between the lines are irreplaceable.

• Why critical thinking and collaboration beat blind enthusiasm: balancing skepticism and excitement.

• The future of AI in organizations and how to move from scattered experiments to an integrated, mature AI practice.

This conversation will give you a new perspective on how to use AI as a creative partner rather than fear it as a rival.
