For accelerators

Workshops that actually move the needle.

No more founders that didn't speak to customers. Only focus on finding customers and getting more of them.

Jeroen running a workshop

Over 25 different accelerators

Several workshops in Booster program

More focus and outreach

"Jeroen's workshops helped our startup to stop talking to everyone, including slow-moving organisations, and focus on our true beachhead market. We got out of our planning phase, because the workshops created social pressure that helped us achieve a peak of 7 customer sales calls booked in 1 week."

Jeroen always has relevant stories from past startup experience

"Jeroen has worked with a lot of startups in and brings all those perspectives to the table. He does that in a no-bullshit direct approach which is very useful for our founders in the early-stage"

Workshop: Deep Customer Interviews

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."

Workshop: Deep Customer Interviews

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"

Several workshops in Mobility PhD 2024

Clarity and actionable insights for real impact
