He helped build up the German Startups Association and co-founded a machine vision classifier, to link locations with emotions.

Tobias Wittich

Director of the Board, Passionate about helping Startups and fostering Entrepreneurship

Tobias' strong belief is that the future of our society and well being depends on creating great companies as well as on spreading the passion for entrepreneurship.
After a career in management consulting in Germany, Japan and Switzerland he dived into the startup scene in Berlin and has been heavily involved ever since. For seven years he built and managed Rainmaking Loft Berlin / The Place, a physical startup only coworking space, that had its own event rooms and café/bar called Le Labo.
He is an active business angel, has served on numerous startup pitch juries, speaks regularly at startup events and provided mentor advice within several startup accelerators.
In Tobias' opinion it is essential to bring people together to create something new and exciting. This can be startups only, but also other parts of society to discuss overarching topics like female entrepreneurship or the future of business. He wants to help educate the political decision makers about the true issues that the startup scene is tackling every day.
