Start to scale. Startup and Scale-up Founder Stories.

Crijn Bouman is a pioneer in EV charging. In 2005 - long before EVs were a hype - he co-founded Epyon, one of Europe’s first fast-charging startups. That company later sold to ABB, where he grew their EV charging business in over 50 countries.

In 2019, he founded Rocsys, making EV charging fully autonomous through a smart combination of Computer Vision, Soft Robotics and AI. With offices in the Netherlands and Portland, Rocsys serves fleet operators: From automated trucks in the port of Rotterdam to robotaxis in the streets of San Francisco.

He’s a man on a mission — and if all goes to plan, one day he’ll fall asleep in a robotaxi in Rijswijk and wake up in St. Tropez.
