17 February 2026· Munich, Germany· energy, construction, industrial_software, b2b, software_hardware

The newly raised capital will be used to expand regional specialist businesses and further digitise the installation process.

Our customers want a local partner who guides them through the entire process—with the highest quality in planning, installation and service. That's exactly what we offer through our regional businesses and digitalized planning.

Tobias Klug, Co-Founder & CEO

We're the skilled trades' answer to the big digital players who focus purely on sales and neglect quality. Our technicians are not just service providers – they're the heart of our company. They are the experts, they plan, install, and deliver excellent craftsmanship.

Competitive Landscape

Direct startup competitors include well-funded 'neo-installers' such as 1komma5° (Series B, $1B+ valuation), Enpal (Series D, solar and heat pump unicorn), Thermondo (scale-up focusing on digital heating solutions), and Vamo (Series A, heat pump subscriptions). Legacy incumbents consist of traditional local HVAC craftsmen and heating engineers who lack digitalized end-to-end planning. Market context: Germany's heating transition is a massive growth category with a national target of 500,000 heat pump installations annually by 2030.
