xWatts is a London-based software company that builds an AI-driven energy management platform for large, complex real-estate portfolios. Unlike solutions that merely analyse data, its software connects directly to on-site systems—such as HVAC, solar arrays, and combined heat-and-power units—to model facilities in real time and automatically optimise both generation and demand. The technology has already been deployed in healthcare, education and manufacturing facilities, where it has delivered reductions in energy use, operating costs and carbon emissions. Target customers are owners and operators of non-domestic buildings across Europe, a segment with high energy intensity and rising decarbonisation pressure. The company’s vision is to decarbonise these assets in an intelligent, automated and scalable way. Proceeds from its latest £1.6 million seed round will fund further product development and expansion in key European markets. No revenue or user figures were disclosed, but the company positions its platform as a mission-critical control layer rather than a passive analytics tool.
