Inertia co-founder Jeff Lawson’s next big bet is fusion: Go inside it at TechCrunch Disrupt 2026

Jeff Lawson has already helped build a company with more than $4 billion in revenue and 300,000 customers worldwide. After scaling Twilio into a public company, his next challenge reaches well beyond software: bringing fusion power to the grid as co-founder and CEO of Inertia.

It’s a striking change in direction. It also raises a question worth exploring: How much of what makes someone a successful software founder carries over when the next business depends on lasers, manufacturing, and major engineering milestones?

At TechCrunch Disrupt 2026 , Lawson will explore that transition in “How Twilio’s Founder Is Tackling the Power Problem.” The fireside chat joins the Smart Systems Stage , where you’ll find the tech infrastructure programming, which includes climate and energy tracks, examining what changes when an experienced entrepreneur takes on a capital-intensive deep tech company.
