Summary
👤
Senior🎓
Top SchoolSimon Spoorendonk is a founder and CEO/CTO who builds high-performance solvers, combining 15+ years of research in combinatorial optimization with hands-on engineering to deliver production-grade systems. He holds a PhD in Computer Science (Operations Research) and has authored 13+ peer-reviewed papers, including one of the most cited articles in Operations Research, and now leads Flowty—an optimized C++ core with Python bindings for multi-commodity flow, vehicle routing, and resource-constrained shortest path problems. His work marries column generation and branch-and-bound with GPU and AVX acceleration, achieving order-of-magnitude speedups on real-world logistics problems and pilots with DHL, Svitzer, Unifeeder and Ørsted. A serial technical founder, he previously built NLP and cloud-native stacks at Onlaw and led optimization consultancies later acquired by larger firms, demonstrating both deep theory and product-market impact. Lately he explores the intersection of optimization and ML, using learned models to guide search inside solvers and rethinking how classical search applies to learned systems. Based in Copenhagen, he also contributes to academia as an external examiner and lecturer, keeping a foot in both research and industry.
