Ethan Thornton, who left MIT at 19 to build weapons, says Mach Industries has focused on getting products shipped through a supply-chain bottleneck—so instead of one bet, it’s now running six weapons programs and closed a $300 million Series C at a $1.8 billio
In a town of about 6,500 people in Burnet, Texas, Ethan Thornton grew up around military ties. Years later, he walked away from MIT at 19, convinced he had to build weapons before the U.S. fell behind the rise of China.
His first prototype didn’t work. The hydrogen-powered system he tried to make—using parts from Home Depot and Amazon—failed to deliver, and Thornton still calls it a bad bet. “Hydrogen was just a bad bet in general,” he said during TechCrunch’s StrictlyVC event in Los Angeles.
By mid-2026, the story has moved on—but the pace hasn’t slowed. Mach Industries, his company, is now running six weapons programs at once. Thornton says the diffuse focus is hard, but not because he’s unsure of the mission. “It’s very hard. ” he volunteered Thursday night. arguing that defense is less like building a single product and more like a chess game played against an adversary—one where “hundreds of different products that need to be shipped if we want security.” Pick just one. he said. and you’ve already lost.
Mach’s portfolio spans a vertical-takeoff strike aircraft. a long-range anti-ship missile. two stratospheric systems. a cheap surface-to-air interceptor designed to kill drones. and—announced earlier this week—a 40-foot. roughly 4. 000-pound Navy logistics-and-strike aircraft. Thornton describes that aircraft as taking off near-vertically, flying over a thousand miles, and carrying a thousand-pound payload. He notes the jump is especially sharp for a company whose biggest aircraft to date has been about 13 feet long.
None of the six programs is in full-rate production yet. Thornton says Mach has won around 13 government contracts. most of them sitting in the middle stage of defense procurement: past initial design and into testing on a government range. but not at the rate-manufacturing tier. He adds that fewer than 10 programs industry-wide have ever reached that tier.
His timeline is aggressive. Thornton says several systems should reach operational deployment by the end of this year. and he wants to push three of the six into rate manufacturing within the same window—moving from hundreds of units a month to hundreds of thousands at a factory Mach says it plans to stand up soon.
The challenge he keeps returning to isn’t whether the technology exists. It’s whether the supply chain can deliver it in time. “The hard part is actually getting the stuff into the building,” he said—naming components like jet engines, solid rocket motors, and radar.
Mach has tried to force that bottleneck open from multiple directions. Thornton says the company built and fired two jet engines from scratch in about eight months. a process he says traditionally takes four years. He also points to its May acquisition of Exquadrum. a 24-year-old solid rocket motor company. for $50 million—described by Thornton as beating out roughly eight other bidders. Selling components, not just vehicles, now accounts for about half of Mach’s revenue.
But Mach’s portfolio strategy puts it in direct contrast to other defense startups that have built their growth on a narrower runway. Shield AI. founded in 2015. spent years as essentially a one-product company around its V-BAT drone before unveiling a second platform. the autonomous X-BAT fighter. last October; Thornton contrasts this positioning as one large. deliberate bet rather than a portfolio. Saronic. founded in 2022. builds only autonomous surface vessels and scales “one unified autonomy stack” across hull sizes from six feet to 180 feet.
Those discipline-driven approaches have come with eye-popping results. Shield AI raised $2 billion this year at a $12.7 billion valuation. Saronic raised $1.75 billion at $9.25 billion.
Thornton’s nearest comparison is Anduril. Mach’s strategy “more closely resembles” Anduril. Thornton said. even while he drew a distinction: “Anduril’s playbook has been very much top-down. starting with the software stack. ” while “We’re very much bottom-up. starting from the hardware stack and then starting to wrap software around it.”.
Still, Mach operates in Anduril’s shadow. Thornton acknowledged the reality without trying to dodge it. Anduril raised $5 billion in May at a $61 billion valuation. and in March it landed a 10-year. $20 billion-ceiling Army enterprise contract consolidating over 120 separate procurement actions. Mach’s ambitions, whatever shape they take, arrive later.
Part of Thornton’s counter-argument is that time and scale are the issue, not just single-company strategy. He points to the volume gap he says exists in missile production: China reportedly builds something like a thousand cruise missiles a day. while the U.S. builds roughly one every three days. “X company and Y company and Z company could all go build these things and it still wouldn’t be enough production. ” he said.
He also argues the Pentagon won’t allow a monopoly, saying it deliberately keeps two or three vendors alive in each category instead of picking one winner.
Even so, questions follow. Thornton was pressed on whether Anduril’s most famous co-founder, Palmer Luckey, has acknowledged Mach publicly. Thornton shrugged off the suggestion that Anduril isn’t interested in making room for Mach. saying he respects Luckey and that they’re “on the same team. ” fighting for the same goal of Western sovereignty.
Mach’s investors—Sequoia, Khosla Ventures, and Ribbit Capital—are largely insulated from the founder’s optics. The company’s betting is reflected in the numbers: earlier this month. Mach closed a $300 million Series C round at a $1.8 billion valuation. Thornton said the startup has raised roughly $485 million altogether.
The most revealing tension inside Mach may be the one Thornton describes as the job changing every six months. He said running the company shifts from engineering first. then sales. and now manufacturing at scale—an emphasis he expects to dominate the next year. He tries to protect four or five hours a day to think and “war game the future. ” sometimes pulling colleagues off their work to do it with him. a move he admitted “can kind of frustrate them sometimes.”.
Keeping him honest, he said, doesn’t come from investors or even his executive team, which can slide into an echo chamber. The hardest feedback arrives from the people actually doing the work.
At Mach, Thornton described routine company-wide forums—his COO’s idea—where employees get microphones and ask him anything. Thornton said it started with him quietly recruiting a few trusted colleagues to ask aggressive questions. and that it evolved into something harder to control and. he suggested. more useful. “I basically stand up there for like an hour. ” he said. “and get asked the most aggressive possible questions by people in the company.” He seems to relish it.
A hydrogen prototype that didn’t work. Six weapons programs running at once. A company pushing toward production at a speed that still sounds almost unbelievable when you name the scale.
What Thornton is trying to prove now isn’t only that these systems can be built. It’s that they can be manufactured, shipped, and deployed quickly enough to matter—while the founder continues to bet that in defense, single-minded focus doesn’t win the game.
