German proptech aedifion has raised €17 million in an oversubscribed Series B financing round. 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 per cent 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 per cent.
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 over 5.8 million square meters. The company has just experienced a period of rapid growth, with annual recurring revenue increasing by 100 per cent year-on-year in 2024-2025.
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.
The round is led by Eurazeo, with participation from existing investor Drees & Sommer. Other investors include VC World Fund, BitStone Capital, Family Office Hopp, and Phoenix Contact Innovation Ventures. Long-standing investors such as MOMENI Ventures, Bauwens Capital, and LARTIS continue to support aedifion and remain invested in the company.
Alice Besomi, Managing Director, and Raphael Cattan, Investment Director at Eurazeo, emphasised 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.
The new funds will be used for European expansion and enhancement of aedifion’s smart building control platform. Upcoming updates include advanced AI-powered energy management features, such as load optimisation and demand-side management.
The company will also launch a generative AI “virtual building assistant” that can understand and respond to user instructions and questions by combining in-house data with large language model capabilities. This assistant will help building owners and operators access data more easily, streamlining reporting, troubleshooting, and maintenance.
