About

I love to dig into customer problems and solve them with modern technology. I help scale and optimize business portfolios that matter – with a focus on sustainable solutions and social impact. To accomplish this, I focus on delivering key outcomes, building teams and quickly adapting to new learnings. I have enjoyed leading positions throughout my career in product management, product marketing, customer success, technical sales, and finance. From mental healthcare (GGZ, VUmc) to sustainable agriculture tech (30MHz, Bayer, LetsGrow), my experience spans organizations where purpose drives progress. These experiences have taught me the following about myself: - I put the customer at the center of all that I do. - My instinct is good but I seek data for my decisions - I love to win, but helping the team win gives me greater joy - I am constantly learning because I never settle - I stay calm when faced with adversity I enjoy meeting new people and hearing new perspectives. Reach out if you want to talk to me about emerging tech, creating software products, wingfoiling, literature or history.
