There is a climate crisis.
And we have a tool to counter it.
To overcome the climate crisis, we need solutions that can be implemented quickly. It takes technologies and successful companies to bring about rapid change.
viboo in brief
If Europe's buildings consume 30% less heat, the continent's energy demand and CO₂ emissions could fall by around 10%. With viboo, we also make this possible for old buildings.

About us
To overcome the climate crisis, we need solutions that can be implemented quickly. Reducing heat consumption in every European building by 30% would reduce the continent's total energy demand and CO2 emissions by around 10%. It takes technologies and successful companies to bring about rapid change.
viboo is based on years of research at Empa and ETH Zurich as well as at other world-leading laboratories for building automation, such as RWTH Aachen and the Lawrence Berkeley National Lab. With our team, we have won numerous grants and awards, such as the BRIDGE Scholarship, all Venture Kick levels, the Gebert Rüf Foundation Innobooster, the Swiss GreenTech Startup Battle, the Empa Innovation Award and the ETH Medal. We are #49 of the TOP 100 startups in Switzerland and #2 in the proptech sector.
Our management team combines complementary skills and experience. Felix Bünning (CEO) and Benjamin Huber (CTO) have co-developed the platform's algorithms, while Matthias Sulzer (Chairman of the Board of Directors), as an experienced energy expert and entrepreneur, contributes a wide range of skills.

GEG becomes GModG
On July 10, 2026, the Bundestag passed the Building Modernization Act (GModG), with the Bundesrat granting its approval on the same day. The GModG replaces the previous Building Energy Act (GEG) and, among other things, repeals the so-called Heating Act—the mandate requiring 65 percent renewable energy for heating system replacements—without replacement. Anyone who immediately thinks of the heating debate when they hear "GModG" may easily overlook one of the most practically significant changes: the substantial expansion of the building automation mandate.
Data-driven renovation: How building automation makes future measures more affordable
Building automation is a worthwhile first step in any renovation project, purely from an economic standpoint: it is the most affordable option with the fastest return on investment. What is often overlooked, however, is that this is where the real value creation begins. Automation brings something else into the building that becomes critical for all subsequent renovation steps: data.
Building automation in the renovation roadmap: The most cost-effective measure with the greatest impact
When renovating inefficient existing buildings, owners face a choice between insulation, new windows, heat pumps, or building automation—all while working with limited budgets and tight regulatory deadlines. A cost comparison shows that building automation delivers the shortest payback period and the highest energy savings per euro invested, making it the ideal first step in any renovation roadmap.
