Welcome to Inertia Enterprises!

Inertia Enterprises, co-founded by laser fusion veteran Mike Dunne, is taking a deliberate approach to commercializing the only fusion method that has achieved energy gain. With $450 million in funding, the company is pairing mass-manufactured targets with efficient diode-based lasers and leaning on proven power conversion technology rather than unproven alternatives. It’s a bet that disciplined engineering will get laser ICF to market faster.
