nuuEnergy raises €4.3 million in seed funding

HTGF portfolio company nuuEnergy, which specializes in regional heat pump installations, has successfully raised €4.3 million in seed financing. The company intends to use the fresh capital to scale its business models across Europe and strengthen craft businesses with digitally supported processes.

The financing strengthens our regional quality standards and ultimately benefits our trade partners.

Investors and financing round

The financing round is led by amberra, the corporate venturing studio of the Cooperative Financial Network (Genossenschaftliche FinanzGruppe Volksbanken Raiffeisenbanken). Other investors include EnjoyVenture and the existing investors Vireo Ventures, better ventures, Bynd Venture Capital and HTGF. HTGF had already led the pre-seed round last year.

Local, digital and artisanal

nuuEnergy combines local presence, digital processes and craftsmanship.

Our customers want a local partner who accompanies them through the entire process - from planning to installation and service. With our new investors, we can further develop and scale our model and strengthen tradespeople in a targeted manner.

Market potential and impact

HTGF Principal Johannes Weber emphasizes:"The heat pump market has regained momentum and nuuEnergy offers a convincing, scalable model. This will enable millions of households to switch to heat pumps without compromising on quality."

With the financing, nuuEnergy can not only grow, but also actively contribute to the local energy transition and strengthen the skilled trades in the region. We already reported on a successful pre-seed financing round for nuuEnergy on Startbase in the summer of 2025.
