Ethan Thornton dropped out of MIT at the age of 19 to build weapons. First, the hydrogen-powered system he prototyped with parts from Home Depot and Amazon didn’t work — “hydrogen was generally a bad bet,” he told TechCrunch this past week. The StrictlyVC event in Los Angeles. Three years later, his company Mach Industriesruns six weapons programs and was shut down earlier this month 300 million dollars Series C is valued at $1.8 billion. The startup has now raised a total of around $485 million.
Thornton grew up in Burnet, Texas, a town of about 6,500 residents, in a family with deep military ties. Around 2017 or 2018 — when he was still in his teens — he began to get “really, really worried” about the rise of China and what he saw as a coming great power conflict. That concern eventually translated into a realization that unmanned systems were about to redefine warfare, and that the United States was moving too slowly to meet the moment.
In practice, what mid-2026 looks like is a company with six weapons programs running concurrently and a lot to prove instead of focusing on one thing, doing it right, and then expanding. Thornton knows that Mach’s diffuse focus raises some lingering questions for outsiders. “It’s very difficult,” he volunteered Thursday night. But he doesn’t think the defense will reward the single-minded focus that a missile launch, for example, requires. “It’s a chess game you’re playing against an opponent,” he said, “with hundreds of different products that need to be shipped if we want to be safe.” Pick just one, he suggested, and you’ve already lost the game.
These are not simple products. Mach is working on a vertical takeoff strike aircraft, a long-range anti-ship missile, two stratospheric systems, a low-cost surface-to-air interceptor designed to kill drones and — he announced earlier this week — a 40-foot, nearly 4,000-pound Navy logistics aircraft with a range of more than a thousand miles. payload.
This last one is a real leap for a company whose largest plane to date is nearly 13 feet long. None of the six are in full production yet. Thornton says the Mach has won about 13 government contracts, most of them in mid-stage defense procurement — past initial design, government range testing, but not reaching production levels, which fewer than 10 programs in the industry have achieved so far.
Several systems should see operational deployment by the end of this year, he says, and his goal is to get three of the six up to speed in production in the same window — which means going from hundreds to hundreds of thousands of units per month at Thornton’s Mach plans to stand up soon.
This is an aggressive chart placed on top of an already aggressive bet. But Mach’s main thesis is that the U.S. can’t outrun China, so it has to outpace it—even though it outnumbers the U.S., finding the first advantage Ukraine has over Russia. “I don’t think we’re going to produce more than China,” Thornton said. “What America has continued to do well over time, compared to what China is based on creativity and productivity.”
As with other defense technology startups, Thornton argues, the real bottleneck isn’t the various platforms being built, but the supply chain beneath them. “The hard part is actually getting the stuff into the building,” he said: jet engines, solid rocket motors, radar. Mach built and launched two jet engines from scratch in about eight months, a process that traditionally takes four years, he said; he also got it in May 24 year old solid rocket motor companyExquadrum, at $50 million, outbid nearly eight other bidders. Now about half of Mach’s revenue comes from selling components, not just vehicles.
Mach’s approach differs markedly from that of some of his peers. Founded in 2015, Shield AI spent years as a one-product company around the V-BAT drone before launching a second platform last October, the autonomous X-BAT fighter — and even that is positioned as a big, thoughtful bet, not a portfolio. Founded in 2022, Saronic builds only autonomous surface ships, expanding a single autonomy stack across hull dimensions from six feet to 180 feet.
Both have been rewarded for this discipline: Shield AI raised $2 billion this year at a $12.7 billion valuation; Saronik raised $1.75 billion for $9.25 billion.
Mach’s strategy is more akin to Anduril’s—it’s bigger, older, and a company that every other defense tech startup is fairly or fairly measured against. Although Thornton claims there is a meaningful difference between the two companies, he draws the comparison himself. “Anduril’s playbook has been very top-down, starting with the software stack,” he said. “We’re going very bottom-up, starting with the hardware stack and building the software around it.”
It’s a difference, yes, but Mach still inevitably operates in Anduril’s shadow. Anduril raised $5 billion in May at a $61 billion deal — 30 times more than Mach — and in March landed a 10-year, $20 billion Army enterprise contract combining more than 120 separate acquisitions. Whatever Mach is building towards, Anduril got there years and tens of billions of dollars ago.
Thornton insists that the field is not zero-sum. He points to the scale of the problem: China is reportedly developing something like a thousand cruise missiles a day; The US builds about one every three days. “Company X, Company Y, and Company Z could all build these things and it still wouldn’t be enough production,” he said. He also argues that the Pentagon would not structurally allow a monopoly — it deliberately keeps two or three vendors alive in each category rather than picking one winner.
Whether or not that was a generous reading of the competitive landscape, I pointed out to him that Anduril’s most famous co-founder, Palmer Luckey, had never, as far as I could tell, publicly acknowledged the Match. Thornton dismissed any suggestion that Anduril was not interested in giving Mach a seat, telling me that he respected Lucki and that they were “on the same team”, fighting for the same Western sovereignty.
Certainly its investors, including Sequoia, Khosla Ventures and Ribbit Capital, couldn’t care less. Strip away the founder-wonderful framework—the Texas workshop, the MIT launch story that every profile, including this one, creates—and what’s left is a genuinely interesting experience led by a founder who, at the very least, seems to know what he doesn’t know.
Thornton made it clear that the hardest part of running Mach changes every six months: first engineering, then sales, and now scale manufacturing, which he expects to dominate next year. He says he tries to reserve four to five hours a day to think and “war on the future,” sometimes pulling his colleagues out of their jobs to do it with him — which he admits “may frustrate them at times.”
Asked who keeps his fast-rising founder honest and pushing him back, Thornton said the most valuable feedback doesn’t come from investors or even the executive team, which may end up in the same echo chamber as the CEO. According to him, it comes from people who actually do the work.
He described the usual company forums, the idea of a COO where employees take a microphone and ask him anything. Thornton began quietly by recruiting a few trusted colleagues to ask aggressive questions. It’s since become something more difficult to control — and, he says, all the more rewarding for it. “I stand there for about an hour,” he said, “and I get the most aggressive questions possible from people in the company.” He seems to enjoy it.
