- Fuchs & Eule, based in Berlin, has secured €10 million in funding led by GET Fund. The company is now shifting its focus from homeowners to commercial landlords, family offices, and asset managers.
- EU rules force 16% of the worst-performing non-residential buildings to be renovated by 2030, rising to 26% by 2033.
- The startup now reports annual CO2 savings of 21.6 tonnes per building, which is more than three times the 6.7 tonnes it reported in 2024.
Property with a high ESG rating is gaining value across Europe. Property with a poor one is losing it. Berlin-based Fuchs & Eule has raised €10 million, saying that the gap will keep widening.
The round is led by GET Fund, with participation from new investors PI Impact and WaVe-X alongside existing backers SET Ventures, Picus Capital and Realyze Ventures. GET Fund plans to back up to 20 high-potential cleantech startups from its current fund.
“Real estate owners know they need to decarbonise their portfolios, but they do not want another tool that adds complexity,” says Robin Behlau, co-CEO at Fuchs & Eule.
The urgency behind the round is not just market sentiment. Under the EU’s revised Energy Performance of Buildings Directive, member states must renovate the worst-performing 16% of non-residential buildings by 2030, rising to 26% by 2033. For office, retail and healthcare landlords, that is a binding compliance deadline, not a voluntary sustainability goal.
The startup was founded in 2021 by Behlau, Tobias Frese, Lina Adrian, Friso Zimmermann and Matthias Kube. It employs 70 people internationally, combining engineering and energy expertise with AI analysis to guide property owners through energy-efficiency retrofits. Its customers are property owners, family offices, and asset managers across the office, finance, insurance, retail, and healthcare sectors.
From homeowners to landlords
At first, Fuchs & Eule worked with homeowners, offering personalised renovation roadmaps and connecting them with financing and contractors. With this funding, it is now targeting professional property owners, family offices and asset managers instead.
The process starts with AI-supported portfolio screening to flag buildings with the greatest potential for refurbishment and value enhancement. From there, it builds digital twins and detailed building analyses, translating them into specific, economically viable renovation measures, plus support navigating grant funding from application through approval.
For example, an asset manager holding a poorly rated office block could use the platform to identify which retrofit measures would most quickly improve its energy rating at the lowest cost, while flagging which subsidies apply.
Competitors are circling the same opportunity. BuildingMinds, a Schindler-backed ESG data platform, offers a comparable AI retrofit recommender for institutional portfolios. Briink applies AI to ESG data extraction and disclosure rather than physical retrofit planning.
Where these platforms focus mainly on data aggregation and reporting, Fuchs & Eule positions its product around translating that data into specific, executable renovation plans.
“Fuchs & Eule stands out by translating building physics into bespoke retrofit measures that make sense both energetically and economically,” says Isabelle Canu, partner at GET Fund.
“Fuchs & Eule is working on one of the biggest decarbonisation levers in Europe,” adds Till Stenzel, partner at SET Ventures, an existing backer returning for this round.
Lotte Stoltenborgh, investment manager at new investor PI Impact, says the company “combines highly granular data, strong AI-powered calculations, and deep expertise to support better decision-making.”
The numbers behind the pitch
The new capital will go toward expanding Fuchs & Eule’s AI technologies, intelligent screening tools, data-driven analyses and personalised renovation advice. It says it has completed 10,000 building analyses covering more than five million square metres since launch, with average savings of 21.6 tonnes of CO2 per building per year. Its total funding to date has not been disclosed.
Europe’s energy retrofit market is valued at more than $200 billion globally, with Europe accounting for roughly 48% of that and growing at a compound annual rate above 6% through 2030, driven largely by binding EU renovation mandates rather than voluntary demand. That regulatory backstop is precisely what Fuchs & Eule and its rivals are counting on.
The open question is whether AI-supported precision is enough of a moat when the real constraint on Europe’s renovation wave is a shortage of construction labour and capital, both largely outside any startup’s control.
