Berlin-based VREY raises €3.3M to unlock shared-roof solar

Berlin-based climatetech startup VREY has closed a €3.3
million seed funding round led by Rubio Impact Ventures, with participation
from High-Tech Gründerfonds (HTGF) and Kopa Ventures.

The company enables property owners to deploy solar systems
in multi-family buildings and supply the generated electricity directly to
tenants, without taking on the role or regulatory burden of an energy supplier.

Nearly half of Europeans live in buildings with shared
roofs, yet solar adoption in this segment remains low. In Germany, fewer than 2
per cent of multi-family rental units use on-site solar, largely due to
regulatory complexity that requires property owners to act as energy suppliers.

A recent regulatory change in Germany introduces a new
framework, “Gemeinschaftliche Gebäudeversorgung”, which removes this
requirement and enables a simpler structure for shared solar deployment. VREY’s
platform is designed to operationalise this framework and make it accessible at
scale.

As a certified smart metering operator and billing partner,
VREY provides an integrated solution for tenant electricity models and
“Gemeinschaftliche Gebäudeversorgung.” Its platform measures each tenant’s
share of solar output and manages billing directly, eliminating the need for
property owners to assume supplier responsibilities while allowing tenants to
benefit without switching providers.

The company currently manages a three-digit number of
projects across all 16 German federal states. Its customer base includes
private landlords, housing cooperatives, project developers, and large real
estate companies. For system installation, VREY collaborates with partners
selected by its customers.

In addition to solar distribution, the platform supports the
integration of batteries, heat pumps, and EV charging infrastructure. VREY
positions its solution as an “EnergyOS” for multi-family buildings, providing a
central layer for measuring, billing, and managing energy flows.

The majority of property owners want to future-proof their
buildings, but until now, practical solutions were missing. With VREY, we make
solar in multi-family buildings simple and economically viable for the first
time,

says Julius Pahmeier, co-founder and Managing Director of
VREY.

With the newly secured funding, VREY plans to expand its
team of around 20 employees and further develop its platform. The company aims
to strengthen its position in the multi-family building segment and unlock
additional energy use cases for property owners.
