Company Overview
About Inertia Enterprises
Inertia Enterprises is a fusion energy company founded by Twilio co-founder Jeff Lawson and Annie Kritcher, the National Ignition Facility lead scientist who oversaw the 2022 fusion ignition breakthrough — the first controlled fusion reaction to achieve scientific net energy gain. The company raised $450 million in Series A financing in February 2026 led by Bessemer Venture Partners and Alphabet's GV, the largest fusion Series A on record.
Business Model & Competitive Advantage
Inertia's technical approach is inertial confinement fusion (ICF), building directly on top of the NIF's proven ignition science. Kritcher's presence gives the company unmatched scientific credibility — she led the team that produced the world's first self-sustaining fusion reaction, and Inertia is now working to translate that laboratory proof-of-concept into a commercial power plant architecture. The company is developing the "Thunderwall" laser beamline targeting a 2030 pilot plant.
Competitive Landscape 2025–2026
The founding team's combination of deep fusion physics (Kritcher) and hyper-growth company building (Lawson, who scaled Twilio from zero to $1B ARR) is unusual in the fusion sector, which has historically been strong on science and weak on commercial execution. The $450 million Series A provides the runway to build the Thunderwall pilot without the funding gaps that have hampered earlier fusion programs.
