Germany’s aedifion raises €17M to help real estate operators cut costs and CO2 emissions

Cologne-based aedifion, a German proptech company, has secured €17M in an oversubscribed Series B funding round led by European growth investor Eurazeo.

The round saw participation from existing investor Drees & Sommer, which significantly increased its commitment, alongside Europe’s climate VC World Fund, BitStone Capital, Family Office Hopp, Phoenix Contact Innovation Ventures, MOMENI Ventures, Bauwens Capital, and LARTIS.

Alice Besomi, Managing Director, and Raphael Cattan, Investment Director at Eurazeo, mention, “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.”

Tackling buildings’ massive carbon footprint

aedifion was founded in 2017 by Johannes Fütterer, Erik Brümmendorf, Jan Henrik Ziegeldorf, and Felix Dorner as a spinoff from RWTH Aachen University’s Institute for Building Technology.

The company’s AI-powered cloud platform enables real estate operators to simultaneously cut energy usage, costs, and CO2 emissions through proactively monitoring and managing heating, ventilation, and air conditioning (HVAC) systems.

aedifion is looking to address a significant environmental challenge: buildings currently account for approximately 36 per cent of energy-related greenhouse gas emissions in Europe. Through its platform, aedifion has proven it can reduce building operators’ CO2 emissions by up to 40 per cent.

The proptech company now manages nearly 500 buildings across Europe, the UK and the US, covering a combined surface area of over 5.8 million square meters. Its platform collects real-time operational data, identifies malfunctions, provides clear recommendations for operational optimisation, and autonomously manages building operations based on real-time data such as weather forecasts and user behaviour.

Currently, aedifion employs over 100 people. Its open API enables integration with other proptech solutions, ensuring interoperability across technology stacks. The platform complies with the German Building Energy Act (GEG), as certified by TÜV Rheinland.

Capital utilisation

aedifion will use the funds to expand across Europe and continue the development of its AI-powered smart building control platform.

The funding will be allocated to European expansion and enhancing the company’s technology, including the development of intelligent energy management solutions via AI-supported load optimisation with demand-side management.

Additionally, the company plans to roll out a generative AI-powered “virtual building assistant” that can receive and answer instructions and questions using both in-house data and LLM capabilities.

Dr.-Ing. Johannes Fütterer, CEO of aedifion, says, “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 optimisation of technical building systems throughout Europe. Our platform has been proven to reduce energy usage by up to 40 per cent – we can thus make a decisive contribution to the decarbonisation of real estate and the preservation of its long-term value.”

aedifion claims that it experienced rapid growth with annual recurring revenue doubling year-on-year in 2024-2025.
