The round was led by the ABN AMRO Sustainable Impact Fund, with GET Fund as co-lead . New investor Aurum Impact also participated, alongside existing backers Emerge VC, Pale blue dot, and noa . VARM plans to use the capital to expand its partner network and Cloud Installer model across new hubs in Germany and eventually across Europe .
VARM's core innovation is not a new hardware device or a software platform alone — it is an integrated labour-focused platform that directly addresses the chronic shortage of certified insulation specialists . Rather than trying to hire scarce existing tradespeople, VARM trains its own specialists, including career changers from adjacent trades like painting or carpentry .
Key elements of the model:
Foundamental, an early investor, described VARM's approach as a "Cloud Installer" model that functions as a "reverse franchise" — VARM trains and kickstarts local teams that operate under the VARM brand using its operating system .
VARM was founded in Berlin in 2023 by two second-time founders :
| Founder | Role | Background |
|---|---|---|
| Christian Grüner (also spelled Gruener) | Co-Founder & CEO | Former management consultant and mathematician; previously founded Vitalon (longevity supplements) . |
| Sebastian Würz (also spelled Wuerz) | Co-Founder & COO | Previously founded homefully (co-living startup) . |
The company's stated mission is to insulate one million homes within 10 years .
VARM's Series A is a capital-efficient bet on what many climate tech investors now see as the true execution bottleneck of the energy transition: not the technology, but the trained workforce to install proven solutions at scale. The company's own press release frames it bluntly: "Heat transition efforts fail less because of technology than because of execution" . By creating new certified workers from career changers — rather than competing for existing scarce labour — VARM is attempting to build the human infrastructure that European building decarbonization has lacked.
