About Koen

After years of working as a freelancer within a collective, Koen seized the opportunity to help build The Overview Effect.

His journey toward sustainability has not been linear. Initially uncertain of his direction, he completed a master’s in Business & IT at the Erasmus University. While his peers joined strategy consultancies and tech giants, Koen felt compelled to seek deeper meaning. His concern about climate change – ironically sparked by extensive travels – led him to start his career in the energy transition sector. Over the decade, his focus has broadened to the broad field sustainability is today. At The Overview Effect, Koen’s mission is to mobilize and empower top sustainability professionals for more impact.
