Berlin-based climate tech startup VREY has closed a €3.3 million seed funding round. The round is led by Rubio Impact Ventures, with participation from High-Tech Gründerfonds (HTGF) and Kopa Ventures. According to HTGF's press release, the investment will help VREY expand its team of around 20 people and grow its platform.
The opportunity is significant. In Germany, nearly 20 million rental units sit in multi-family buildings, yet fewer than 2% are powered by on-site solar. The main barrier has always been legal: to share solar power with tenants, property owners had to register as energy suppliers, a burden most were unwilling to take on.
A recent change in German regulation, introducing the so-called "Gemeinschaftliche Gebäudeversorgung" framework, removes that requirement. VREY turns this regulatory opening into a practical product. As a certified smart metering operator, the company measures each tenant's share of solar output and handles all billing through its software. Landlords keep the revenue, tenants pay less for their electricity, and neither party needs to deal with the complexities of the energy supply market.
Founded in Berlin in 2024 by Cedric Jaeger and Julius Pahmeier, VREY already has a three-digit number of projects running across all 16 German federal states. Clients include private landlords, housing cooperatives, and large real estate companies. The platform also supports batteries, heat pumps, and EV charging, positioning VREY as what it calls the "EnergyOS" for multi-family buildings.
With fresh capital in hand, the team is focused on scaling fast in a market that has barely been touched.
