Equip your cohort with tools to actually find product-market fit

Hands-on workshops based on working with 500+ founders and my scientific research on early-stage startups

Entire team leveled up in a day

"The workshop contains many new sharp tactics that go beyond the standard 'ask about the problem; even the more experienced interviewers got new perspectives. Thanks to the many interactive exercises, we were able to learn how to apply them and go in-depth. As a result, the quality of our interviews improved immediately, and people are already conducting more interviews by themselves"

Our founders got an ongoing

validation mindset

"Jeroen’s workshop helped my cohort realize that validation is an ongoing process, not a one-time exercise. The lessons of the exercises helped founders long after the program ended."

Clarity and actionable insights for real impact
