Deutsche Sanierungsberatung (dsb) operates as a digital platform and marketplace focused on energy-efficient home renovations in Germany. The company was established in Berlin in 2024 by Sebastian Schmidt, Niclas Kern, and Adam Khenissi, all of whom previously worked at the German energy unicorn Enpal. Their shared experience, which includes scaling a heat pump company to significant revenue, underpins dsb's mission.
The firm targets the significant market of German homeowners facing the need to comply with EU energy efficiency standards, which mandate that approximately 16 million buildings require upgrades by 2033. dsb aims to simplify what is often a complex and fragmented renovation process for consumers. It acts as a neutral, manufacturer-independent consultant, removing homeowners' lack of trust in disparate service providers.
The core of dsb's service is a digital platform that facilitates the planning of comprehensive renovation measures, from insulation and window replacements to the installation of heat pumps and solar PV systems. The customer journey begins with an initial consultation, followed by the creation of an Individual Renovation Roadmap (iSFP). This detailed plan, based on a 3D model of the property, outlines the most effective and eligible measures for energy savings, which can reduce costs by up to 90%. The business model generates revenue through consulting fees for creating these roadmaps, commissions from brokering projects to its network of vetted local craftspeople, and a service fee for managing government subsidy applications (such as KfW and BAFA), ensuring homeowners maximize their financial benefits. In February 2025, the company secured €3.6 million in a seed funding round led by Vireo Ventures, with participation from IBB Ventures, FJ Labs, and Saxovent, to enhance its platform and accelerate growth.
