Our take

Traditional energy companies often prioritise profit over sustainability, leading to high prices and reliance on fossil fuels. Fuse Energy aims to disrupt the energy market by offering lower prices and cleaner energy options.

It does this by building solar farms that ensure access to cheap, renewable energy. Its data science team forecasts energy demand and buys additional power from gas and electricity markets, providing a mix of renewable and traditional sources.

With €76M in annualised revenue and 7x year-on-year growth, it now supplies 50,000 homes and plans to expand into Ireland, Europe, and the US. Backed by new AI features and with investments into clean energy, Fuse is truly shaping up to redefine the future of home energy.
