Green Fusion secures 12 million euros for AI-supported heating optimization

Reduce heating costs, protect the climate: Smart heating systems instead of expensive conversions - Green Fusion is revolutionizing the heating transition and plans to expand in Europe.
Berlin, January 21, 2025 - Clean-tech startup Green Fusion has successfully closed a Series A financing round of 12 million euros. Leading investors are HV Capital and XAnge, accompanied by existing investors such as BitStone Capital, Übermorgen Ventures and Vireo Ventures. With the new financial injection, the company aims to drive the scaling of its AI-based heating optimization solution and accelerate its European expansion.
Smart solutions for immediate efficiency gains
Green Fusion specializes in the digitalization and real-time optimization of heating systems in apartment buildings. The innovative software analyzes data from heating systems, detects inefficiencies and dynamically adjusts the controls to reduce energy consumption and CO₂ emissions. Customers report average savings of 16% on heating costs.
Our technology makes it possible to implement the heating transition immediately, without the expensive and time-consuming conversion of heating systems. We use intelligent control to maximize efficiency
Paul Hock, Co-CEO of Green Fusion
Investing in growth and European expansion
According to Green Fusion, the fresh capital will flow into the areas of sales, product development and customer support. The aim is to optimize 3,000 heating systems by the end of 2025, a growth rate of 300 %. The company is also planning to enter the French, Benelux and other European markets. Pilot projects are already underway in Austria and Italy.
Relevance for the housing industry and climate targets
In view of rising CO₂ prices and political climate neutrality targets by 2045, housing companies are under strong pressure to reduce energy consumption. While structural refurbishments require high investments, Green Fusion offers an immediately implementable solution with low installation costs that quickly pays for itself through savings. Customers already include well-known housing companies such as Gewobag and Rheinwohnungsbau.
Market leader in heating optimization
According to GdW President Axel Gedaschko, optimizing energy consumption is "a crucial first step towards achieving climate targets, even before the widespread use of new technologies such as heat pumps". Green Fusion's technology is already regarded as a leader in the industry.
Our focus is on making every heating system smarter - heating more efficiently today and preparing for the transformation to renewable systems such as heat pumps tomorrow
Paul Hock, Co-CEO of Green Fusion
The successful financing round strengthens Green Fusion's role as a driver of innovation for climate-friendly heating control in Europe. The next few years will show how the minimally invasive technology can hold its own in a growing market. We reported about a round back in 2022 and the startup also successfully closed a seed round in 2023.
