What happened
Twilio co-founder Jeff Lawson has launched Inertia, a fusion energy company that raised a $450M Series A led by Bessemer Venture Partners in February 2026. The company opened a 50,000 sq ft HQ in Livermore, California in July, focusing on laser systems and fusion fuel target manufacturing, and Lawson will discuss the transition from software to deep tech at TechCrunch Disrupt 2026 in October.
Why it matters
This is primarily a conference promotion piece with no actionable takeaway for builders. The only useful signal is that a proven software founder is betting that capital-intensive deep tech (fusion) is the next frontier, which may inform founders considering whether to move from SaaS into hardware or energy — but there is no technical or strategic detail here to act on.
Discussion angle
Whether the playbook of a successful software founder (APIs, developer experience, land-and-expand) transfers at all to a capital-intensive fusion company, or whether this is purely a capital-allocation and talent-recruitment game where software instincts are irrelevant.
