NuuEnergy closes its seed round with €4.3 million. Amberra, the corporate venturing studio of the Cooperative Financial Group Volksbanken Raiffeisenbanken, leads the financing. Enjoy Venture also participates, as do existing investors HTGF, Vireo Ventures, Better Ventures and Bynd Venture Capital.

The startup was founded in late 2023 and focuses on building regional heat pump installation businesses. The company designs and installs heat pumps and enters into long-term maintenance contracts. It also distributes value-added services such as water softening systems or energy consulting. With the fresh capital, the startup is advancing the establishment and expansion of regional specialist trade businesses and further digitalizing the installation process.

Regional hubs with digital support

Switching to heat pumps can significantly reduce buildings’ CO2 emissions. At the same time, skilled labor shortages and inefficient processes are slowing the market. NuuEnergy addresses this and positions itself between traditional craft businesses and digital “neo-installers”. The company attracts skilled workers to its regional hubs through modern software tools and attractive working conditions. Currently, technicians are working in the Munich metropolitan area, Hamburg, and Cologne.

“Our customers want a local contact person who guides them through the entire process – with the highest quality in planning, installation, and service. With the cooperative financial group and Enjoy Venture, we now have additional strong partners on board who support us with capital and expertise in developing our business model. The cooperative banks can additionally support our customers with tailored financing solutions and give the heat transition further momentum locally”,

explains Tobias Klug, co-founder of NuuEnergy.

“This benefits our regional, quality-focused orientation. Last but not least, our craftspeople, the heart of our company, benefit from this too”,

adds Julia Rafschneider, co-founder of NuuEnergy.

Investors bet on craft trades

The investors also emphasize the strategic significance of the investment. Björn Schmuck, managing director of Amberra, comments:

“With our investment in NuuEnergy, the cooperative financial group is actively shaping the energy modernization of residential buildings in Germany. The cooperation with the startup enables Volksbanken Raiffeisenbanken to combine regional value creation with digital financing processes. Particularly convincing about NuuEnergy was the close collaboration with local craft businesses – and thus also with our banks’ customers.”

And Gerrit Gnisa, investment manager at EnjoyVenture, says:

“Most of our investors are deeply rooted in the mid-market themselves. We strongly believe in NuuEnergy’s mission and positioning, in the goal of bringing real, regional craftsmanship into the future. With NuuEnergy, I can say in good conscience: I would buy a heat pump from them myself. It’s not about digital sales for them, but about genuine, long-term innovation in craftsmanship and technology.”
