German proptech startup aedifion Secures €17Million in Series B round

Founded in 2017 as a spinout from RWTH Aachen University, the company was started by Johannes Fütterer, Erik Brümmendorf, Jan Henrik Ziegeldorf, and Felix Dorner.

The problem they’re tackling is huge — buildings are responsible for about 36% of energy-related greenhouse gas emissions in Europe.

aedifion’s AI-powered cloud platform helps building operators cut CO₂ emissions by up to 40%. The solution is already being used in Austria, Switzerland, Luxembourg, the Netherlands, Poland, the UK, and the US, managing nearly 500 buildings across 5.8 million square meters.

The company has seen strong momentum, with annual recurring revenue doubling 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 €17 million Series B round was led by Eurazeo, with continued support from existing investor Drees & Sommer. New backers include VC World Fund, BitStone Capital, Family Office Hopp, and Phoenix Contact Innovation Ventures.

Long-time investors like MOMENI Ventures, Bauwens Capital, and LARTIS have also reaffirmed their commitment to aedifion.

Alice Besomi (Managing Director) and Raphael Cattan (Investment Director) at Eurazeo highlighted aedifion’s strong potential to drive energy efficiency and sustainability in the building sector.

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 funding will support aedifion’s expansion across Europe and further development of its smart building control platform. Upcoming upgrades will introduce advanced AI features for energy management, including load optimisation and demand-side control.

aedifion also plans to launch a generative AI-powered “virtual building assistant” that uses in-house data and large language models to understand user questions and instructions. This assistant will make it easier for building owners and operators to access insights, manage reports, troubleshoot issues, and handle maintenance tasks more efficiently.
