Zurich’s Viboo Secures €3.3M To Expand AI-Powered Building Management In Germany

The funding will drive its expansion into Germany and evolve its energy management tool into a comprehensive building management system.

viboo’s cloud based platform retrofits commercial buildings wirelessly connecting to common IoT devices like smart thermostats. Its AI learns heating patterns and optimizes energy use achieving savings of up to 27% without sacrificing comfort or requiring high upfront costs. The platform is already deployed in over 100 buildings, with contract volumes growing eightfold between winter 2023/24 and winter 2024/25.

Avoiding proprietary hardware, viboo integrates with leading building tech via open software interfaces. An installer app allows rapid deployment by qualified installers. The company sells directly to municipalities and property owners, while partnering with installation and facility management providers.

The new funding will support Germany’s rollout—boosted by the Building Energy Act—and expand the platform with modules like individual heating cost billing. Realyze Ventures’ LP network will also aid go-to-market efforts, with initial LPs already securing building implementations.

Felix Bünning, Co-Founder of viboo, said: “We have built a strong foundation in Switzerland – with more than 40 satisfied customers, some already rolling out across portfolios, and significant energy savings in existing buildings. Our solution convinces because it is easy to implement, delivers fast results, and generates immediate savings. Now we are taking the next big step with our entry into our first EU market, where a combination of energy prices and regulation creates a strong pull. Realyze Ventures was our preferred partner from the start, thanks to their deep industry expertise and excellent network. With Zürcher Kantonalbank, we are also adding one of Switzerland’s most renowned early-stage investors.”

Marnix Roes, Investment Manager at Realyze Ventures, said: “With viboo, we are investing in an innovative software solution that drives the decarbonization of existing buildings and addresses a huge market. The easy and fast implementation, combined with rapid ROI leads to high satisfaction among customers and users. Through our broad Realyze Ventures ecosystem, we will actively accelerate viboo’s go-to-market in Germany.”

Nicola Leuenberger, Investment Manager at Zürcher Kantonalbank, added: “viboo clearly demonstrates how economic and ecological goals go hand in hand. With a plug-and-play solution delivering 20–40% energy savings annually, viboo should be on every real estate asset manager’s roadmap. We look forward to supporting viboo in the upcoming scaling phase.”
