Ethan Thornton dropped out of MIT at age 19 to make weapons. The first, a hydrogen-powered system he prototyped with parts from Home Depot and Amazon, didn’t work: “Hydrogen was just a bad bet in general,” he told me last week on TechCrunch. Strictly VC Event in Los Angeles. Three years later, his company, Mach Industriesis running six weapons programs and earlier this month closed a $300 million Series C round with a valuation of $1.8 billion. The startup has raised approximately $485 million in total.
Thornton grew up in Burnet, Texas, a city with approximately 6,500 residents, in a family with deep military ties. Around 2017 or 2018, when he was still a teenager, he began to become, by his own account, “very, very concerned” about the rise of China and what he saw as an impending great-power conflict. That concern eventually deepened into the conviction that unmanned systems were about to redefine warfare and that the United States was moving too slowly to meet the moment.
What that looks like in practice, in mid-2026, is those six simultaneous weapons programs and a company that has a lot to prove instead of focusing on one thing, getting it right, and then expanding. Thornton is aware that Mach’s diffuse approach creates some lingering questions for outsiders. “It’s very difficult,” he volunteered Thursday night. But he doesn’t think defense rewards the kind of concentration that, for example, launching a rocket requires. “It’s a chess game you’re playing with an adversary,” he said, “with hundreds of different products that need to be shipped if we want security.” Pick just one, he suggested, and you’ve already lost the game.
These are not simple products. Mach is working on a vertical takeoff attack aircraft, a long-range anti-ship missile, two stratospheric systems, a cheap surface-to-air interceptor built to kill drones and, announced earlier this week, a 40-foot, roughly 4,000-pound Navy attack and logistics aircraft that takes off nearly vertically and flies more than a thousand miles with a thousand-pound payload.
The latter is a real leap for a company whose largest aircraft to date measures about 13 feet long. And none of the six are yet in full production. Thornton says Mach has won about 13 government contracts, most in the middle stage of defense procurement: beyond initial design, through testing at a government range, but below the level of manufacturing that fewer than 10 programs industry-wide have reached.
He says several systems should be operational by the end of this year, and his goal is to push three of the six to accelerate manufacturing in that same window, which would mean going from hundreds of units per month to hundreds of thousands, in a factory that Thornton says Mach plans to start up soon.
It’s an aggressive timeline that adds to an already aggressive bet. But Mach’s underlying thesis is that the United States can’t outmanufacture China, so it has to outmanufacture it: find a first-mover advantage, as Ukraine has done against Russia, despite being outproduced. “I don’t think we’re going to surpass China in manufacturing,” Thornton said. “What the United States continues to do well, time and time again, compared to China, is focused on creativity and productization.”
Thornton argues, like other defense technology startups, that the real bottleneck is not the various platforms being built, but the supply chain beneath them. “The hard part is really getting all 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 he says traditionally takes four years; also acquired in May a 24-year-old solid rocket motor companyExquadrum, for $50 million, beating out approximately eight other bidders in his own words. Sales of components, not just vehicles, now account for about half of Mach’s revenue.
Mach’s approach differs markedly from that of some of his peers. Shield AI, founded in 2015, spent years essentially as a single-product company around its V-BAT drone before unveiling a second platform, the X-BAT autonomous fighter, last October, and even that is being positioned as a big deliberate bet, not a portfolio. Founded in 2022, Saronic builds solely autonomous surface vessels, scaling a unified autonomy stack in hull sizes from six feet to 180 feet.
Both have been rewarded for that discipline: Shield AI raised $2 billion this year at a $12.7 billion valuation; Saronic raised $1.75 billion ($9.25 billion).
The company that Mach’s strategy most closely resembles is Anduril, which is bigger, older, and the one company that all other defense technology startups are compared to, fairly or not. Thornton makes the comparison himself, although he maintains there is a significant difference between the two companies. “The Anduril playbook has largely been top-down, starting with the software stack,” he said. “We’re very much bottom-up, starting with the hardware stack and then starting to wrap it with software.”
It’s a distinction, yes, but Mach inevitably continues to operate in Anduril’s shadow. Anduril raised $5 billion in May at a valuation of $61 billion (more than 30 times that of Mach) and in March secured a 10-year, $20 billion capped Army enterprise contract that consolidates more than 120 separate acquisition actions. Whatever Mach’s goal, Anduril got there years and tens of billions of dollars early.
Thornton insists that the field is not zero-sum. He points out the magnitude of the problem: China reportedly makes something like a thousand cruise missiles a day; The United States builds about one every three days. “Company X, Company Y and Company Z could build these things and there still wouldn’t be enough production,” he said. He also maintains that the Pentagon structurally will not allow a monopoly: that it deliberately keeps two or three suppliers alive in each category rather than picking one winner.
Whether or not it’s a generous reading of the competitive landscape, I tell you that Anduril’s most famous co-founder, Palmer Luckey, has never, to my knowledge, publicly acknowledged Mach. Thornton ignores any suggestion that Anduril is not interested in making room for Mach, telling me that he respects Luckey and that they are “on the same team,” fighting for the same goal of Western sovereignty.
No doubt its investors, including Sequoia, Khosla Ventures and Ribbit Capital, don’t give a damn. Strip away the founder-prodigy framework (the Texas workshop, the MIT dropout story that drives every profile, including this one), and what’s left is a genuinely interesting experiment run by a founder who seems, at least, to know what he doesn’t know.
Thornton has been candid that the hardest part of running Mach changes every six months: first engineering, then sales, and now scale manufacturing, which he hopes to master next year. He says he tries to set aside four or five hours a day to think and “play against the future,” sometimes taking his colleagues out of their work to do it with him, which, he admits, “can sometimes frustrate them a little.”
On the question of who pushes him—who keeps a fast-growing founder honest—Thornton said the most valuable feedback doesn’t come from investors or even his executive team, who can end up in the same echo chamber as the CEO. It comes, he said, from the people who actually do the work.
He described routine company-wide forums, the brainchild of his COO, where employees get microphones and ask him anything. It all started when Thornton quietly recruited some trusted colleagues to ask aggressive questions. Since then, it has become harder to control and, he suggested, more useful. “I basically stand there for an hour,” he said, “and people at the company ask me the most aggressive questions possible.” He seems to enjoy it.
