VARM, a Berlin-based climatetech startup, is tackling Europe's building energy efficiency gap by offering a full-service insulation solution. The company has just closed a €17.5 million Series A funding round to accelerate its expansion across the continent.

The round was led by ABN AMRO Sustainable Impact Fund and co-led by GET Fund, with additional participation from Aurum. This capital injection will support VARM's mission to retrofit existing buildings with modern insulation, reducing energy consumption and carbon emissions.

Europe's aging building stock presents a massive market opportunity, with millions of structures requiring energy-efficient upgrades to meet climate targets. VARM competes in a crowded field of home energy retrofit startups, but its end-to-end service model—handling everything from assessment to installation—may give it an edge.

The funding signals growing investor appetite for climatetech solutions that address the built environment, a sector often overlooked in favor of flashier clean energy plays. As regulatory pressure mounts for building efficiency standards, VARM could find itself in a sweet spot.

Founder and CEO Johannes Lorenz previously co-founded a property tech firm, bringing domain expertise to the venture. The company plans to use the new funds to enter additional European markets and build out its technology platform.
