Berlin‑based ClimateTech SaaS Deutsche Sanierungsberatung closed a Series A round of over €10 million (US$11 million) on July 21 2026, led by Simon Capital and VERBUND X Ventures, with existing backers IBB Ventures, Vireo Ventures and Atlantic Food Labs participating again.
Deal Terms
The round, valued at more than €10 million, will fund a proprietary electricity tariff, the company’s first foray into the B2B market, and further scaling of its digital platform that matches homeowners with vetted tradespeople for climate‑neutral renovations. The company previously secured a €3.6 million seed round in February 2025. Nico Heinz, Principal at Simon Capital, said dsb solves a concrete problem for property owners and an overloaded trades sector, creating productivity gains at the intersection of renovation and energy transition.
Strategic Rationale
Founded in 2024, dsb digitises the entire renovation journey—from energy consulting and subsidy processing to implementation—by creating a digital twin of each home and generating an individualized renovation roadmap (iSFP). The platform claims to cut homeowner time‑to‑completion by roughly 80% and now serves over 10,000 private customers. CEO Sebastian Schmidt emphasized the broader climate imperative, noting that residential buildings account for about 30% of Germany’s CO₂ emissions. The new capital will expand the network of 300 local trades businesses, accelerate the rollout of the electricity tariff, and enable a B2B offering aimed at property managers and housing associations.
The company projects 2026 revenue exceeding €15 million, reflecting rapid scaling since its 2024 launch. CFO Niclas Kern highlighted that the round demonstrates investor appetite for GreenTech business models even as AI dominates capital flows. CCO Adam Khenissi underscored the untapped market, with roughly 80% of Germany’s 15 million single‑family homes still lacking energy‑efficient upgrades.
Why It Matters
The infusion of €10 million positions dsb to outpace emerging German renovation platforms that rely on fragmented contractor networks. By bundling consulting, subsidy navigation, and execution under a single SaaS interface, dsb can capture higher gross margins and lock in recurring revenue from its electricity tariff and B2B contracts. Competitors will need to accelerate their own digital integration or risk losing market share to dsb’s end‑to‑end solution. For investors, the round validates a scalable SaaS model in a regulated, high‑volume market, suggesting that climate‑focused vertical SaaS can attract sizable capital despite broader AI hype.
For the broader German climate‑tech ecosystem, dsb’s success may spur additional venture activity in building‑stock efficiency, prompting incumbents in utilities and real‑estate to explore SaaS partnerships or acquisitions to secure a foothold in the renovation value chain.

Analysis
While the exact valuation multiple was not disclosed, dsb’s projected €15 million revenue for 2026 suggests a valuation in the low‑double‑digit millions, aligning with typical early‑stage SaaS multiples of 5‑8× ARR for high‑growth vertical players. The round underscores a resurgence of investor confidence in ClimateTech SaaS that tackles regulated, capital‑intensive markets. As European policy pushes for deeper building‑stock decarbonisation, platforms that can digitise subsidy processing and contractor coordination are likely to command premium multiples. For operators, the deal highlights the importance of building a unified customer journey that blends productized services with recurring revenue streams such as electricity tariffs. Investors should watch for follow‑on funding rounds that may further compress valuation gaps between ClimateTech and AI‑centric SaaS, especially as utility partnerships become a key growth lever.
