Munich-based energytech startup
nuuEnergy, which focuses on building regional heat-pump installation
businesses, has secured €4.3 million in seed funding. The round was led by
amberra, the corporate venturing studio of the Cooperative Financial Network
Volksbanken Raiffeisenbanken, with participation from EnjoyVenture and existing
investors HTGF, Vireo Ventures, better ventures, and Bynd Venture Capital.
The heat pump sector has seen strong
growth in recent years despite a slowdown in 2024. Around 229,000 units were
sold last year, and annual installations could reach up to 500,000 by 2030,
according to the German Heat Pump Association. While heat pumps can
significantly reduce building-related CO₂ emissions, growth remains constrained
by skilled labour shortages and inefficient installation processes.
Founded in late 2023, nuuEnergy aims
to address these challenges through a locally focused, digitally supported
installation approach. The company generates revenue through planning,
installation, and long-term maintenance contracts, with additional income from
services such as water treatment systems and energy consulting.
To build regional specialist
businesses, or “hubs,” nuuEnergy focuses on attracting skilled workers through
modern software tools and structured working conditions. The company positions
itself between traditional craft businesses and digitally focused installation
models. Digitised processes and on-site system planners support tailored
technical planning for each building and aim to improve installation
efficiency.
Commenting on the funding, Tobias Klug, co-founder of nuuEnergy, said customers are looking for local partners
that guide them through the full process, from planning to installation and
service, adding that the new investors will support the development of the
company through both capital and expertise. He also noted that cooperative
banks can provide tailored financing options to support local heating
transition projects.
Julia Rafschneider, co-founder of
nuuEnergy, added that the approach strengthens the company’s regional,
quality-focused strategy and supports its skilled workforce.
The newly raised capital will be used to expand
regional specialist businesses and further digitise the installation process.
