Jeff Lawson, co-founder and CEO of fusion energy startup Inertia, will share insights on applying software entrepreneurship experience to the capital-intensive fusion sector at TechCrunch Disrupt 2026 in San Francisco this October.
- Jeff Lawson shifts focus from software to fusion energy with Inertia
- Inertia secured $450M Series A for fusion laser and fuel target development
- Lawson to discuss deep tech leadership challenges at TechCrunch Disrupt 2026
What happened
Jeff Lawson, who previously scaled Twilio into a multi-billion dollar public technology company, is now leading Inertia as it aims to bring fusion energy to commercial viability. The company recently raised a $450 million Series A round led by top venture firms including Bessemer and GV. This financing supports the development of powerful laser systems and mass manufacturing techniques for fusion fuel targets, essential components required for Inertia’s fusion power approach.
Alongside the funding milestone, Inertia opened a 50,000-square-foot headquarters in Livermore, California, where they are developing manufacturing and laser technologies. The company has also added leadership talent from prominent firms such as Apple, Corning, and Waymo to strengthen their manufacturing and supply chain expertise. Jeff Lawson will be discussing this transition from software to fusion and the operational challenges involved at TechCrunch Disrupt 2026 in October.
Why it matters
Lawson’s move from software to fusion energy highlights how experienced technology founders are expanding into capital-intensive and scientifically complex industries. Fusion power technology requires navigating engineering challenges, long development timelines, and deep scientific expertise, quite different from software product cycles and market dynamics. Understanding this shift offers valuable lessons for entrepreneurs and investors interested in deep tech commercialization.
This conversation is important because fusion energy promises a transformative impact on the global energy landscape, offering a clean, potentially limitless power source. Inertia’s progress illustrates the convergence of venture scale funding and rigorous engineering necessary to transition fusion from experimental setups to grid-scale energy production. Lawson’s leadership experience in building teams, products, and securing funding provides a crucial perspective on bridging these demanding domains.
What to watch next
At TechCrunch Disrupt 2026, Lawson’s fireside chat will delve into the specific challenges of leading a fusion startup, including talent recruitment across diverse fields, setting credible technical milestones, and managing fundraising for a capital-intensive deep tech venture. This session will offer insights relevant to founders working in climate tech, hardware, and scientific innovation sectors striving to scale complex technologies.
Investors and industry watchers should look for updates on Inertia’s progress in demonstrating technological breakthroughs as well as milestones in manufacturing capacity. The company’s ability to integrate scientific innovation with large-scale industrial processes will be key indicators of fusion energy’s commercial potential. Close attention to Lawson’s approach may reveal broader strategies for managing innovation in hard-to-solve global problems.
