Summary
🤩
Rockstar🎓
Top SchoolMarcel Rieser is a founder and managing director with 18 years of experience building and shaping large-scale transport simulation software, combining a Dr.-Ing. in Transport Planning with an MSc in Computer Science. As founder of Simunto and former CTO/co-founder of Senozon, he has led development of visualization and analysis tools for massive spatio-temporal datasets (Via) and been a core developer of the widely used MATSim multi-agent transport simulation. He bridges academic rigour and product delivery—having completed a PhD thesis on public transport simulation and adapted MATSim for major operators like SBB—while still contributing backend refactors and engine-level optimizations to the open-source codebase. Based in Zurich, he pairs deep domain expertise in transport modelling with hands-on software engineering and a track record of turning complex mobility research into production-ready tools.
