Green Riding – be part of tomorrow

On my way to work I mostly see cars with only one passenger, even though they are all driving in the same direction. We have to change that. I want to leave something for my children



The combination of shared rides and active environmental protection is exactly the kind of engagement I find exciting.


Founder and CEO

We need to think differently about how we use our own cars. We can only bring about a mobility turnaround by taking advantage of shared rides and the digital possibilities
