Startup Rhein Neckar is a great website dedicated to showing the full scope of the startup community in the Rhine-Neckar region. You can find startups, accelerators, incubators, coworking spaces, investors and much more! If you have your own startup that you want to feature there don't hesitate and send a request.
We here at MCEI love the site as it aims for the same than we do - to create a strong startup community in the Rhine-Neckar region. Special thanks to Michael Schilonka, the creator of the map, and RepresentLA.
