Twilio Founder Jeff Lawson Shifts to Fusion Energy with New Startup Inertia

Jeff Lawson built a major software company before turning to fusion power as his next focus.

He now serves as co-founder and chief executive of Inertia.

Inertia Secures Huge Investment for Fusion Development

The startup raised four hundred fifty million dollars in a Series A funding round.

This money supports work on laser systems and mass production of fusion fuel targets.

In July the company opened a fifty thousand square foot headquarters in Livermore California.

Executives from Apple Corning and Waymo joined to strengthen manufacturing efforts.

Applying Software Lessons to Deep Tech Challenges

Lawson gained experience at Amazon Web Services and as founding chief technology officer at StubHub.

His background helps address team building and milestone setting in hardware heavy fields.

Fusion aims to deliver clean abundant energy to power grids around the world.

This move shows software veterans bringing fresh approaches to complex energy projects.

The session at TechCrunch Disrupt 2026 will explore these transitions in detail.
