"Sjoerd was a member of our advisory board when Axora was taking its first steps. His direct approach and marketplace experience made him an invaluable addition to our team. He challenged our thinking and made a telling impact in the critical early stages when we were figuring out how to make our business work. Any founder building a marketplace would benefit from his input, and I would very much recommend working with him."

For our marketplace, Sjoerd was a really valuable sparring partner and coach when we were diving deeper into our liquidity analysis and performance improvements. He is a real expert on how digital marketplaces really work and his sharp and direct way of pointing to the right places gets you working on the “problem zones” fast. I highly recommend getting him involved if you want to take your marketplace to the next level.”
