Erwin van Rooijen


Background in Automotive Engineering, which got me involved in the future of mobility. Worked at two large automotive companies (General Motors, Renault), which sucks when you want to innovate. I started the company 2,5 years ago, and we now want to create more mobility with less cars. We just launched the beta version of our car sharing platform, and are looking for participants: car owners and people who occasionally need cars. Shared Tesla’s, BMW’s, and Porsches for everyone.

I am a ‘Rotterdammer’ in the true sense of the word. I have a passion for our city and love helping it develop, progress and grow through my job as communications advisor at Rotterdam Partners. Working together with people and organisations with different backgrounds, beliefs and agendas, but with a common goal and purpose: to help Rotterdam move forward! I also love running, playing golf, (fine) dining, movies (GO IFFR!!), reading and writing… oh so many things, so little time

Daniel Maas

I’ve never just done something. I believe it’s interesting to look at the world around us and think about what could be different. Better. More interesting. That’s why I started The Fittery. Because it’s not off this world anymore to work out when your gym has the time to host you. You decide when. Where. With whom. The Fittery. Your work out, on demand.
