Decarbonizing buildings. Designed to scale.

Buildings are responsible for 20% of global CO₂ emissions. In Germany alone, 80% of residential energy use goes into heating and hot water. Traditional renovation is expensive, slow and often ineffective.

termios offers a new path: an AI-powered, cloud-based system for hydraulic balancing — installed in existing buildings with just a few components, delivering 30% energy savings.

But beyond the product lies a bigger story — one of shared vision and joint execution across industry boundaries.

LEG Immobilien, Germany’s second-largest residential real estate holder, was facing a massive challenge: how to optimize energy efficiency in hundreds of thousands of flats - without deep renovation?

Oventrop, a leading manufacturer of hydraulic systems, knew the limitations of conventional balancing solutions.

What was missing? A venture partner with a builder’s mindset - someone to turn the problem into a scalable company.
