Profitable German heat pump platform GALVANY closes €10 million Seed round after sevenfold revenue growth

GALVANY Energy (GALVANY), a Berlin-based heat pump platform, has closed a €10 million Seed financing round to further expand its end-to-end platform for the installation, operation, and optimisation of heat pumps in Germany, with particular emphasis on the existing-building market for multi-family homes.

The round was led by Dutch EnergyTech investor SET Ventures, with Berlin-based ClimateTech fund AENU as co-lead.

Raik Belka, Founder and CEO of GALVANY, said, “We are building the infrastructure that will finally make the heat transition work in the existing-building stock. In Germany, heat pumps do not fail because of the technology, but because of the gap between subsidy bureaucracy, installation capacity, and economic viability for the end customer. 

“This is exactly the gap we are closing — with a platform that makes every link in the chain measurably better while sustaining itself. Closing this round from a profitable position is more than just a metric for us: it is proof that the heat transition is financeable without combustion logic.”

Founded in 2022 by Raik Belka, GALVANY is an end-to-end platform for the heat transition. The company states that it combines sales, procurement, installation, and intelligent operation of heat pump systems in a single system. The platform finances profitable growth, multi-family-home scaling, and AI-powered energy management

At its core are the GALVANY Cube, produced together with Panasonic, and the GALVANY Fusion energy management system. The company’s hardware element is called GALVANY Cube, which is complemented by a modular system architecture in which the heat pump, battery storage, and the GALVANY Fusion energy management system work in concert.

According to the company, in contrast to the market standard, GALVANY relies on a networked platform ecosystem: instead of an expensive direct sales operation, the company integrates acquisition, procurement, installation, and management into a single solution.

It claims that based on dynamic electricity tariffs, load shifting, and spot-market arbitrage, heating and electricity costs are measurably reduced. V1 of the GALVANY app is scheduled for release in the summer, enabling digital control of an entire energy system.

“The next phase of the energy transition will not be decided by hardware, but by the software that intelligently links generation, storage, and consumption. GALVANY is one of the few European companies that consistently thinks this logic through from the end device all the way to the power grid. With the platform and the energy management system, the heat pump evolves from a heating device into an active element of a digitally controlled energy system,” said Dr. Till Stenzel, Partner at SET Ventures.

With this funding, the company plans to focus on the multi-family-home existing-building market and expand the offering for housing companies and portfolio holders. It also plans to further develop GALVANY Fusion as an Agentic Energy OS, which involves further development of the AI-powered energy management system that orchestrates load profiles in real time and translates dynamic electricity tariffs into measurable end-customer savings.

GALVANY also aims to expand partner structures with installation contractors and its own sales organisation to accelerate nationwide platform scaling.

To date, the company has installed more than 2,500 heat pump systems, avoiding over 3,850 tonnes of CO₂. In 2025, GALVANY generated revenue of €20.1 million, a sevenfold increase compared to the previous year, and closed the year with a positive EBIT.
