Jeff Lawson, co-founder and former CEO of Twilio, has recently discussed his transition to leading Inertia, a fusion energy company focused on commercializing inertial confinement fusion. In podcast and conference appearances, he reflected on Twilio’s go-to-market challenges, noting that the company generated significant revenue with a small sales team, and described how AI is shifting software spending toward headcount budgets. He also stated that his experience at Twilio informs Inertia’s approach to talent, fundraising, and timelines, while acknowledging that fusion development operates on longer horizons than software. Lawson discussed Inertia’s technical strategy, including the use of advanced lasers and mass-manufactured fuel targets, and expressed optimism about factory economics driving down costs for fusion and solar energy. He cited the 2022 breakthrough at Lawrence Livermore National Laboratory as a foundation for the company’s work. Inertia announced a $450 million Series A led by Bessemer in February and opened a facility in Livermore, California for laser development and target manufacturing. Lawson also commented on the luxury of pursuing a long-term moonshot project without needing to prove himself, and noted that Inertia is hiring scientists and engineers.

Notable quotes

“People are not tapping into software budgets. They're tapping into headcount budgets, which are far far bigger. So if you're saying, oh, you don't need to hire as many lawyers, as many developers, as many customer service agents because you've got AI that can essentially do their job. You know, in the past, you'd look at SAS and you'd say, 'Oh, well, maybe if I buy CRM for my salespeople, everyone got 10% more produc”

“The way to think about it is that up until now our data center business has been almost entirely GPUs. Vera is our CPU, and you know what's really exciting is that Vera opens a brand new 200 billion TAM for NVIDIA, a market we have never addressed before, and every major hyperscaler is partnering with us to get it deployed, and that's huge for the company because for the first time we have a second engine of that sca”

“I think by 2050 we'll have demonstrated that the two forms of energy that are the only ones that are being built at that time are solar with battery and fusion for a simple reason. I think they're the two forms of energy that are going to benefit from factory economics. And every other form of energy where you know every project is bespoke struggles to achieve economics, struggles to build at scale, struggles to see ”

“I think SaaS is going to die. ... The real answer is no, it's not going to die, of course, but it will stop growing and may even shrink. The reason why is ... any business based on seats has a real innovator's dilemma.”

“The promise of fusion is that if you can have cheap energy that is made out of abundant resources on Earth that will never run out, that is both clean and safe. Right? This is the holy grail of humanity's energy needs.”

“I think there's an over-rotation in the stock market, first of all. So, I think people are overly concerned. And look, it if a stock price today is the present value of all future profits, do I think future profits of CRM companies and software companies broadly that are especially those that are based on a per seat basis have been curtailed by AI? Absolutely. Right? So, there is an argument that I think is true that”
