Inside Fuse Energy: Alan Chang on Building a $5B Energy Giant and Chasing £1B ARR

In this episode of Riding Unicorns, host welcomes back Alan Chang, founder and CEO of Fuse Energy, to reflect on the company’s meteoric rise from a nascent energy startup to a $5 billion valuation firm on track to achieve £1 billion in annual recurring revenue (ARR). Alan candidly discusses the immense complexity of the energy industry, emphasizing that true disruption requires owning the entire system—not just parts of it. A pivotal strategy involves acquiring and operating grid infrastructure, a bold move that positions Fuse as a systemic player rather than a mere energy provider. He highlights tangible achievements like a 15% reduction in energy costs through automation, AI support, optimized forecasting, and in-house engineering, with further innovations like a consumer-friendly micro solar and battery product on the horizon. Alan also shares his mindset: driven by urgency, self-doubt, and a relentless focus on speed over capital, he views time as the ultimate constraint. Despite early success, he remains unsatisfied, constantly pushing forward. The conversation reveals a deep conviction that energy is one of the world’s most critical problems—and one that can be solved with the right team, vision, and execution. Alan’s ability to attract top talent by offering ownership, impact, and a mission-driven culture is framed as Fuse’s secret weapon. The episode closes with a forward-looking vision: a continent-scale energy leader that slashes costs by 20–30%, enabling breakthroughs in AI, manufacturing, and sustainability. Key takeaways include: 1) True disruption in legacy industries like energy requires systemic ownership, not incremental innovation; 2) Speed and time efficiency are more critical than capital in high-complexity markets; 3) A mission-driven culture that offers ownership and impact is the best way to attract elite talent; 4) Product design must be both functional and beautiful to drive mass adoption; 5) The most successful founders are those who embrace complexity and are driven by fear of not moving fast enough. Alan’s journey from Revolut to Fuse exemplifies how culture and conviction can be replicated to build transformative companies.
