On this episode of BILLIONS, I'm sitting down with Alan Chang, Co-Founder and CEO of Fuse Energy—a tech-driven energy company that has completely shattered the UK market.

Alan was employee #3 and Chief Revenue Officer at Revolut. Instead of coasting on fintech success, he and his co-founder Charles took that hyper-growth playbook and weaponized it against traditional utility giants like British Gas and Octopus.

In just three years, Fuse has exploded from £2M to £400M in annual revenue, achieving a £5 billion valuation.

If you want to know how a lean tech team can buy a wind turbine, acquire a grid operator, and out-execute legacy multi-billion dollar incumbents, this is your blueprint. In this masterclass, we break down:

The Revolut Exit: Why Alan walked away from fintech because the problem was "largely solved".
The £1M MVP: How they bought an energy license for £50K and a single wind turbine for £750K, using a mix of their own capital and an early round.
Anti-Democracy Culture: Why running a startup by committee fails, and why top performers should be paid 10x more than bottom performers.
Full-Stack Infrastructure Control: Why Fuse is currently buying a grid operator to dominate supply.
Internal AI Weaponization: How Fuse is building internal AI agents (PR reviews and error-tracking) to keep their team incredibly small and efficient.
