About

I help fintechs, banks, and growth-stage software companies across the U.S., U.K., and Europe turn AI into real products, workflows, and decision systems, either through focused high-leverage sprints or as a Fractional Chief AI Officer. My work sits at the intersection of agentic AI, ML-driven decisioning, product strategy, and hands-on execution. I focus on financial crime, credit decisioning, compliance workflows, and AI-enabled operations, helping leadership teams prioritize the right use cases, design workable systems, and get them into practice. Previously, I scaled Klarna’s data science organization from 20 to 110+ scientists, served as Chief Data Officer at Catawiki, and founded the first Dutch startup accepted into Y Combinator.
