aedifion, the leading PropTech helping commercial property operators simultaneously cut costs and emissions, has raised €17 million in an oversubscribed Series B financing round. The round is led by European growth investor Eurazeo, which specializes in investments in private equity, private debt, real estate, and infrastructure. Existing investor Drees & Sommer is significantly increasing its commitment. Other existing investors, including Europe’s leading climate VC World Fund, along with BitStone Capital, Family Office Hopp, and Phoenix Contact Innovation Ventures, are reaffirming their commitment and participating in the round. Other long-standing investors such as MOMENI Ventures, Bauwens Capital, and LARTIS continue to support aedifion and remain invested in the company.
aedifion was spun out of RWTH Aachen University’s Institute for Building Technology by Johannes Fütterer, Erik Brümmendorf, Jan Henrik Ziegeldorf and Felix Dorner in 2017. The scale of the problem they are tackling is enormous: buildings currently account for around 36% of energy-related greenhouse gas emissions in Europe. Through using aedifion’s smart, AI-powered cloud platform, building operator customers have already managed to reduce their portfolio CO2 emissions by up to 40%. Customers in Austria, Switzerland, Luxembourg, the Netherlands, Poland, the UK and the US already use aedifion to manage nearly 500 buildings with a combined surface area of 5.8 million+ square meters.
The company has just experienced a period of rapid growth, with annual recurring revenue increasing by 100% year-on-year in 2024-2025. The aedifion team will now use their fresh capital to expand across Europe and continue to improve its market-leading smart building control platform. Updates will include further intelligent energy management solutions via AI-supported load optimisation with demand side management, and the roll out of a generative AI-powered “virtual building assistant”. The assistant can receive and answer instructions and questions, using both in-house data and LLM capabilities. It enables owners and operators to access building data quickly and accurately, simplifying reporting, troubleshooting and maintenance.
Dr.-Ing. Johannes Fütterer, CEO of aedifion GmbH, commented: “With Eurazeo, we have gained an experienced growth investor that shares our vision of sustainable, data-driven real estate. Smart buildings and artificial intelligence will play a crucial role in the energy transition. This new funding will enable us to further scale our solution and establish aedifion as the leading platform for the digital operational optimization of technical building systems throughout Europe. Our platform has been proven to reduce energy usage by up to 40 percent – we can thus make a decisive contribution to the decarbonization of real estate and the preservation of its long-term value.”
Alice Besomi, Managing Director, and Raphael Cattan, Investment Director at Eurazeo, emphasized aedifion’s strong potential: “With this investment, via our Eurazeo Smart City Fund II, we are supporting aedifion’s mission to make buildings smarter and more energy-efficient. Their scalable platform is the easiest solution for asset managers to drive energy efficiency and emissions reduction across real estate portfolios. We’re excited to help scale their impact across Europe.”
