Koen Hooning combines a background in applied physics and econometrics with hands-on experience at firms like Oliver Wyman and Helin Data, and this shows up in a portfolio built around hard-science, industrial climate technologies such as E-magy, Vertoro, Canopus Drilling Solutions, Magneto, FononTech, RABLE, and HR Energy, where he often takes board or supervisory roles rather than staying purely on the cap table. His work is closely tied to the Dutch technical ecosystem, particularly Delft-linked research networks, and he tends to back technologies that expand where climate solutions can be used, from RABLE's solar mounting system for weak roofs to Vertoro's platform for turning lignin into fuels, chemicals, and materials.
