Inertia raises $450 million to commercialize the only proven fusion science

LIVERMORE, Calif., Feb. 11, 2026 (GLOBE NEWSWIRE) -- Inertia Enterprises, the commercial fusion energy company, today announced a new $450 million investment to bring limitless clean energy to the world. The Series A round was led by Bessemer Venture Partners, with participation from additional firms including GV (Google Ventures), Modern Capital, Threshold Ventures, and more.

Founded in 2024, Inertia will build a fusion pilot plant based on the physics proven at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL). The milestone-based funding will advance Inertia's plans to build the world's most powerful laser, Thunderwall, and a production line to mass manufacture fuel targets at scale. These technical tracks lay the foundation for Inertia to deliver grid-scale energy through a phased commercialization roadmap.

With the support of its investors and a team purpose-built to deliver grid-scale energy, Inertia will bring to market the only fusion energy approach proven to produce more power than it consumes.

"Inertia is building on decades of science and billions of dollars invested to reach the ignition milestone that proved the science," said Jeff Lawson, the co-founder and CEO of Inertia and former founder and long-time CEO of Twilio. "Our plan is clear: build on proven science to develop the technology and supply chain required to deliver the world's highest average power laser, the first fusion target assembly plant, and the first gigawatt, utility-scale fusion power plant to the grid. Inertia is building the team, partnerships, and capabilities to make this real within the next decade."

Constructing the first fusion energy power plant to deliver grid-scale power requires as much technical expertise as it does capital. The Inertia team has decades of experience ...
