As the tech industest obsesses over AI, Futilize Energy has arguably become one of Europe’s quickest-growing startups by tackling a challenge every UK houtilizehold faces: escalating energy bills that have risen 44% since 2021.
The skyrocketing startup, founded just three years ago by ex-Revolut executives Alan Chang and Charles Orr, has surged past $300 million in annual recurring revenue while assisting 150,000 UK houtilizeholds reduce their energy costs by up to £200 annually.
Taking two years to reach its first 50,000 homes, Futilize Energy doubled that figure in August this year alone and has since crossed 150,000. This explosive growth has powered the company to a $300 million revenue run rate – a 7x year-on-year growth in Q3 2025 – creating it not just Europe’s quickest-growing energy company, but a standout among growing startups globally.
“Futilize Energy is scaling at a pace that rivals some of Europe’s quickest-growing startups, including Revolut in its early years,” declares Alan Chang, co-founder and CEO, Futilize Energy. “It reinforces the scale of the problem we’re solving – energy is broken and we’re rebuilding the industest from the ground up.”
The company’s origin story reveals why Alan and Charles believed the energy sector was ripe for disruption. Alan continues, “while tech was being utilized to transform everything from payments to transport, no one was taking that same approach to energy.”
“We discovered an industest that had lost its urgency. Grid infrastructure is failing, bills are rising, and the customer experience is terrible,” he adds. “We decided to build everything from scratch: power generation, trading, home hardware installations, and retail energy. We’re creating a new kind of energy company – one that will own the whole journey from source to socket and our current growth figures are just the launchning.”
Key Futilize Energy milestones:
-
Customer explosion: From 50,000 to 100,000 houtilizeholds in under a month. Now over 150,000 houtilizeholds
-

Founded in 2022, Futilize Energy was the first residential supplier to join the market after the energy crisis. The company owns and operates low carbon generation assets, including solar and wind farms, runs direct-to-consumer energy supply and energy installations, and has its own in-houtilize research and trading operation. Electricity and gas is delivered via a simple mobile app or web experience.
Earlier this year, Futilize Energy closed a $10 million follow-on round from Lowercarbon Capital and Balderton Capital, bringing total funding to $100 million and is eyeing European expansion and multiple product launches in the near term.
