Dübendorf ZH/Zürich/Köln, October 2025

Viboo AG has successfully completed its second financing round, the Dübendorf-based company, which was founded in 2022, announced in a press release. A total of 3.3 million euros was raised from existing and new investors. The spin-off from the Swiss Federal Laboratories for Materials Science and Technology has developed a tool for optimising the use of energy in buildings.

Viboo intends to use the new funds for its upcoming entry into the German market. To this end, the start-up wants to expand its energy management tool into a comprehensive tool for building management. “We have laid the foundations in Switzerland – with over 40 satisfied customers, some of whom are already in the portfolio roll-out phase, and significant energy savings in existing buildings,” said viboo co-founder Felix Bünning in the press release. “We are now taking the next big step by entering our first EU market, where the combination of energy prices and regulation is providing a strong pull.”

The financing round that has now been concluded was led by Realyze Ventures from Cologne. “With viboo, we are investing in an innovative software solution that drives the decarbonisation of the existing building segment and thus addresses a very large market,” said Marnix Roes, Investment Manager at Realyze Ventures, in the press release. Viboo has also gained Zürcher Kantonalbank(ZKB) as a new investor. The bank is looking forward to “supporting viboo in the upcoming scaling process”, explains Nicola Leuenberger, Investment Manager at ZKB.
