"After working for months on my innovative bike lock, Jeroen helped me to focus on getting my product to market. He held me accountable to doing things that move the needle, and see through the noise. At the end of my collab with Jeroen, I reached 100+ sales, and felt comfortable to continue by myself. With a philosophical tangent here and there, he's helped me to get unstuck and ahead as a founder"

"You can easily convince yourself a side quest is worth it. Jeroen asks the tough questions to keep your eyes on the prize. He drives velocity through weekly accountability and focusing on the right things. It keeps you away from distractions."

"Jeroen is an additional brain. Someone who shares your ambitions, has relevant experience and knowledge, and can provide support at a deeply personal level. Sanity checks when you need them."

"Jeroen is my sounding board for strategic decisions. Our calls help me validate my direction, sharpen my ideas, and identify the next improvements. It keeps me moving forward with confidence."

"I needed a structured approach to scale my sales calls and tactics for smoother conversations. With Jeroen’s input, I walked into those meetings feeling more confident than ever."

10/10 would recommend. Jeroen helped me get better focus on what's the most important priority. Asks the right questions to dive deep and gives very actionable advice with real examples based on the many startups he worked with.

Jeroen is the best! Helpful insights and sanity checks. Walked away with action points we are excited to execute on. Would recommend for any founder.

"He helped me to shift my mind away from what I offer to focus on the customer. From supply to demand. This has helped me to sharpen my value proposition immensely"

"Jeroen doesn't beat around the bush. He highlighted what customer information I missed in a direct way, I immediately knew where to focus. That's the kind of feedback I prefer to hear, cold and early."

"By working with Jeroen, I've learned how to turn big ideas into small experiments. This increased momentum and focus for our startup. We now know what works, without spending 6 months of building it."
