There is a climate crisis and an energy security crisis. We have a tool to help mitigate them.

About us

To tackle the climate crisis, we need solutions that can be implemented quickly. Reducing every Swiss building’s heating consumption by 30% will reduce the country’s total energy demand and CO2 emissions by about 10%. It needs technologies and successful businesses to bring about fast change. 

viboo is rooted in years of research at Empa and ETH Zurich, as well as other world-leading building automation labs such as RWTH Aachen and Lawrence Berkeley National Lab. With our team, we have won a BRIDGE fellowship, all Venture Kick stages, the Innobooster by Gebert Rüf Stiftung, the Swiss GreenTech Startup Battle, the Empa Innovation Award, and the ETH medal. 

Our management team combines complementary skill sets and experiences. Felix Bünning (CEO) and Benjamin Huber (CTO) have cocreated the algorithms of the platform, while Matthias Sulzer (president of the board) contributes with a vast skillset as a seasoned energy sector expert and entrepreneur.
