Munich, June 24th 2025 – 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 was led by European growth investor Eurazeo, which specialises in investments in private equity, private debt, real estate, and infrastructure. aedifion’s existing investors also participated, including Drees & Sommer, Europe’s leading climate VC World Fund, BitStone Capital, Family Office Hopp, and Phoenix Contact Innovation Ventures. Long-standing investors such as MOMENI Ventures, Bauwens Capital, and LARTIS also continue to support the company.

aedifion was spun out of RWTH Aachen University’s Institute for Building Technology by Johannes Futterer, Erik Brummendorf, 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 management 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 their market-leading smart building control platform. Updates will include further intelligent energy management solutions via AI-supported load optimisation and 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.
