Inertia Enterprises, founded in 2024 by Twilio co-founder Jeff Lawson with NIF scientists Annie Kritcher and Mike Dunne, plans a laser inertial fusion power plant based on LLNL's NIF ignition physics. It raised a $450 million Series A in February 2026 and intends to begin plant construction in 2030.

Notes
Construction start 2030 is a company intention; no site or power rating disclosed. private funding raised not recorded because pre-Series A funding is not disclosed (the $450M Series A is the known figure). Plant design needs a 10 kJ, 10 Hz laser architecture.
