Fuchs & Eule has raised €10m to expand its AI-powered platform for building energy renovation. The company helps professional property owners identify, prioritise and implement the retrofit measures that can improve energy performance, reduce emissions and protect asset value.
The funding round was led by GET Fund. New investors included PI Impact and WaVe-X, alongside existing investors SET Ventures, Picus Capital and Realyze Ventures.
Fuchs & Eule will further expand its digital business model, including AI technologies, intelligent portfolio screening tools, data-driven building analyses and personalised renovation advice. The company’s approach is set to help property owners move from complex energy-efficiency decisions to clear, investable renovation plans.
Across its projects, Fuchs & Eule achieves average savings of 21.6 tonnes of CO₂ per building per year.
Fuchs & Eule addresses decarbonisation challenges with a data-driven, done-for-you retrofit solution for professional property owners. Its platform combines AI-supported portfolio screening, detailed building analysis, digital twins, engineering expertise and subsidy advice.
This enables property owners to understand which buildings should be renovated first, which measures make economic sense and how to turn energy-efficiency plans into implementation.
“The biggest hurdle is not the willingness to renovate, but the complexity of the decisions. We make them manageable, with AI-supported analyses, clear recommendations for action and sound advice for the entire property portfolio.”
Dr Tobias Frese, Co-CEO, Fuchs & Eule
Fuchs & Eule begins by screening property portfolios to identify the buildings with the greatest potential for energy savings, emissions reduction and value improvement.
The company develops detailed building analyses and digital twins, which are used to define specific retrofit measures. This includes heating, ventilation and air-conditioning upgrades, improvements to the building envelope and other energy-efficiency measures.
Fuchs & Eule supports clients with grant funding, from identifying suitable subsidy programmes to preparing applications. This is particularly important in a market with high investment costs and limited internal capacity.
By combining software, data and energy expertise, Fuchs & Eule gives property owners a practical route to improve building performance while supporting the wider energy transition.
For SET Ventures, Fuchs & Eule sits at the intersection of energy efficiency, digital infrastructure and real estate value creation.
Existing buildings is an important decarbonisation lever in Europe, but the market holds fragmented data, technical complexity and generic retrofit advice. Fuchs & Eule’s model addresses this by turning building-specific data into clear recommendations and actionable renovation plans.
“Fuchs & Eule is working on one of the biggest decarbonisation levers in Europe- the existing building stock.
“By combining granular data, AI-supported analysis and deep building expertise, the team helps property owners make better retrofit decisions at scale.
“We are very pleased to continue supporting the company as it grows in this market and delivers impact through data-driven insights and solutions.”
Dr Till Stenzel, Partner, SET Ventures
European regulation also accelerates the need for building renovation. Under the EU Buildings Directive, member states must ensure that 16% of the worst-performing non-residential buildings are renovated by 2030. By 2033, this rises to the worst-performing 26%.
“I have been working on building retrofits since their launch in 2005, and I have been frustrated by the one-size-fits-all recommendations with inconsistent quality.
“Fuchs & Eule stands out by translating building physics into bespoke retrofit measures that make sense both energetically and economically. That is why I am excited to back the team.”
Dr Isabelle Canu, Partner, GET Fund
Every building is different, which means owners need specific, data-backed guidance on what to renovate, when to act and how to make projects economically viable.
“Fuchs & Eule has built an impressive model that combines highly granular data, strong AI-powered calculations and deep expertise to support better decision-making.”
