aedifion Raises $18.3M to Advance AI-Driven Building Optimization Across Europe
German proptech company aedifion has secured €17 million ($18.3 million) in an oversubscribed Series B funding round to scale its AI-powered building operations platform. The Cologne-based company, spun out of RWTH Aachen University in 2017, enables building owners and operators to reduce energy consumption, CO₂ emissions, and costs through real-time, cloud-based system optimization. This round was led by Eurazeo, with participation from Drees & Sommer, VC World Fund, BitStone Capital, Hopp Family Office, Phoenix Contact Innovation Ventures, and continued support from MOMENI Ventures, Bauwens Capital, and LARTIS.
Targeting the 36% Problem in Europe’s Emissions
Buildings account for approximately 36% of Europe’s energy-related greenhouse gas emissions. aedifion addresses this challenge with a platform that automates diagnostics, monitoring, and control of HVAC and energy systems across large real estate portfolios. According to the company, building operators using its software have reduced emissions by up to 40%, supporting both sustainability and cost-efficiency goals. The system currently supports nearly 500 buildings totaling 5.8 million square meters in markets including Austria, Switzerland, the UK, and the US.
This funding comes on the heels of a period of rapid growth: aedifion reported 100% year-over-year growth in annual recurring revenue in 2024–2025. The capital will be used to enhance its product suite with advanced features such as load optimization, demand-side management, and a new generative AI “virtual building assistant” that enables users to query building data and optimize performance through conversational interfaces.
AI and Energy Tech as a Strategic Investment Frontier
aedifion’s ability to attract a wide range of financial and strategic investors highlights a growing appetite for AI-powered energy tech solutions in commercial real estate. Investors are betting on platforms that deliver both measurable ROI and regulatory alignment in markets increasingly driven by ESG mandates and energy performance standards. The forthcoming generative AI tools are expected to improve user accessibility to building data, streamlining reporting and facilitating proactive maintenance—further aligning property operations with decarbonization goals.
As the EU tightens climate disclosure regulations and performance benchmarks, aedifion positions itself as a mission-critical infrastructure layer for institutional landlords and property managers across Europe and North America. The Series B raise underscores a broader trend: AI-native proptech companies focused on operational decarbonization are rapidly gaining traction in both venture and enterprise circles.
