Berlin’s dsb Secures €10M to Revolutionise Home Energy Renovations

Berlin-based ClimateTech startup Deutsche Sanierungsberatung (dsb) has secured over €10 million in a Series A funding round, aiming to accelerate its mission of making residential homes climate-neutral. The investment, led by Simon Capital and VERBUND X Ventures, will support the launch of a proprietary electricity tariff, expansion into the B2B market, and further platform growth.

Nico Heinz of Simon Capital highlighted dsb’s role in addressing a critical gap: “Millions of property owners struggle with renovation decisions, while the trades sector faces inefficiencies in customer acquisition. dsb’s tech-driven approach streamlines the process, boosting productivity and advancing the energy transition in existing buildings.” Founded in 2024, dsb provides end-to-end support for homeowners, from energy consulting and subsidy processing to connecting them with vetted trades businesses.

Germany’s residential sector accounts for roughly 30% of the country’s CO2 emissions, primarily due to fossil fuel-based heating. dsb tackles this by creating digital twins of homes, enabling tailored renovation roadmaps that prioritise measures over time and secure funding bonuses. The platform also handles all funding applications, reducing homeowners’ time investment by about 80%.

Since its inception, dsb has grown rapidly, serving over 10,000 customers and projecting €15 million in revenue for 2026. CFO Niclas Kern noted, “While AI dominates investment, our growth proves that sustainable business models still attract capital.” The company plans to expand its network of 300 trades businesses and enter the B2B sector.

As CCO Adam Khenissi reflected, “Two years ago, we were researching insulation materials. Today, we’ve helped thousands of families, but with 80% of Germany’s 15 million single-family homes still energy-inefficient, the journey is just beginning.”
