Zurich-based viboo has raised €3.3 million in its second financing round, led by Realyze Ventures with participation from Zürcher Kantonalbank, HTGF, Swisscom, and other new investors. The funding will support the company’s entry into the German market and expand its AI-powered platform from energy management to a holistic building management solution.
Buildings account for more than 40% of global CO₂ emissions, and stricter EU regulations require upgrades to avoid asset devaluation. viboo’s platform connects wirelessly with IoT devices such as smart thermostats, learning heating patterns and proactively managing systems to cut energy use without major interventions.
Already deployed in over 100 buildings, viboo reports average energy savings of 27% and a significant expansion in contract volumes between winter 2023/24 and 2024/25. Its plug-and-play design and installer app allow rapid deployment by existing service providers.
“With more than 40 satisfied customers and significant energy savings already achieved, we are now taking the next big step with our entry into our first EU market. Realyze Ventures was our preferred partner from the start thanks to their deep industry expertise and network.” ~ co-founder Felix Bünning
Realyze Ventures’ investment manager Marnix Roes said viboo “addresses a huge market” and that its combination of “easy and fast implementation combined with rapid ROI” drives strong customer satisfaction. Nicola Leuenberger, investment manager at Zürcher Kantonalbank, added that viboo shows how “economic and ecological goals go hand in hand” with 20–40% energy savings.
viboo is rooted in research at Empa, ETH Zurich, RWTH Aachen, and Lawrence Berkeley National Lab, and has won multiple awards including the Empa Innovation Award and ETH Medal. It partners with hardware manufacturers such as Siemens and Danfoss, and installation firms like Hälg, to scale its solution across Europe.
