Before 2022High School, Jobs and First Prototypes
TechCrunch writes that around 2017 or 2018, in his early teens, he became “really, really concerned” about China’s rise and a possible great-power conflict, a concern that grew into the belief that unmanned systems would redefine warfare and that the United States was moving too slowly. Fortune writes that his interest in defense began before he was old enough to drive.[1][2]
TechCrunch wrote in 2023 that he worked as an auto mechanic in high school and ran a small business selling handmade kitchen knives, cutting boards and other products. The Mach Industries website states that he funded early prototypes for defense-related technologies with savings from his work as an auto technician; the episode page of The Shawn Ryan Show states that he began prototyping weapons in high school, funded through car tech jobs, knife and furniture sales and small engineering projects; and Inside Unmanned Systems states that he founded Mach Industries with funds saved from a manufacturing business he started in high school. In March 2025 he recalled in TechCrunch: “Back in high school, I ran a wood and metal workshop to actually bootstrap the company.”[8][7][4][9][10]
TechCrunch writes that he developed an obsession with electrolysis and that its first result, made while he was still in high school, was a small arms device: a couple of deer feeder batteries and an electrolyzer powering what was essentially a bazooka, costing around $200 and paid for by his parents after he pitched them with a 20-page paper; Forbes likewise writes that in high school he borrowed $200 from his parents to build a basic gas gun with “deer feeder batteries and an electrolyzer.”[8][6]

Fortune writes that he studied aerospace at MIT, where he also made the football roster.[2]
September–Late 2022: The Predecessor of Mach Industries
The Orange County Business Journal stated in June 2024 that a predecessor of Mach Industries was incorporated in September 2022, while the paper’s April 2024 article states that the company had largely operated in stealth mode since its founding a little more than three years earlier. Forbes states that the company was founded at the end of 2022 as Trident Industries and later renamed Mach. Mach Industries’ own press release and website give 2023 as the year of its founding.[3][14][6][15][7]
Forbes writes that he persuaded a team of hydrogen experts from MIT Lincoln Laboratory, led by Erik Limpaecher, to join him; TechCrunch wrote in July 2023 that Erik Limpaecher, a senior technical staff member with nearly 12 years at Lincoln Laboratory, had become Mach’s chief innovation officer and that Mark Donahue, a former program manager with 15 years at the laboratory, had become vice president of engineering. A pitch deck seen by Forbes shows that the company’s early products were named after Greek gods, including the Medusa drone and the Hades reconnaissance balloon.[6][8]
2023Leaving the Massachusetts Institute of Technology
Sources differ on when he left MIT: TechCrunch wrote in July 2023 that he finished his first year at MIT in the spring of 2023 and then decided to drop out; Fortune writes that he received a Thiel FellowshipThiel FellowshipThe Thiel Fellowship is a two-year grant program started by investor Peter Thiel and run by the Thiel Foundation that funds young people who skip or stop out of college to build new things instead. The program has been criticized by figures in education for encouraging young people to leave college.Open the full entry before finishing his first year and left MIT to work on his company full-time; the Orange County Business Journal states that he dropped out after his first semester; and the episode page of The Shawn Ryan Show states that he left MIT after one semester in 2023 to focus on building Mach full-time.[8][2][3][4]
In 2023 he said that he “just couldn’t sit through classes anymore,” and that “I don’t like doing anything halfway,” calling leaving school a clear decision that he did not regret. In 2025 he described dropping out as “probably the highest risk thing I did,” since it came “before we had capital, or before I had a team.”[8][10]
2023A Hydrogen Gun Explodes During a Test
Forbes wrote in 2024 that four former employees with knowledge of the matter said that during a test he was reaching into a blast chamber surrounding a hydrogen-powered gun when the gas unexpectedly ignited; the explosion destroyed machinery and sent shrapnel across the room. He was unharmed, while a colleague helping with the test was rushed to hospital with hundreds of pieces of metal in his body; the colleague recovered, though some shrapnel remains. Forbes writes that months before the company’s financing, he and the employee were almost killed while testing a Mach weapon.[6]
TechCrunch wrote in 2025 that the accident, which injured a team member, happened a few months before Sequoia Capital’s seed investment in the summer of 2023 and that Forbes first disclosed it; he attributed it to a lack of safety resources, saying “we didn’t have the money to sort of run these procedures the way they should have been,” and said that the company “essentially shut down all work” until Sequoia Capital’s funding arrived. The article states that the company has since built a full safety team.[16]
February 8, 2023Selected as a Thiel Fellow
On February 8, 2023, the Thiel Foundation announced its next class of 20 Thiel Fellows, listing him third; the announcement describes his project as Mach Industries pioneering a suite of defense systems using new inventions in the hydrogen space. The announcement states that the Thiel Fellowship encourages talented young people with big ideas to start companies instead of attending college, and that during the two-year program fellows receive $100,000 and mentorship from the Thiel Foundation’s network of founders, investors and scientists, the only requirement being that they pause college enrollment.[5]
The Thiel Fellowship was founded by Peter ThielPeter ThielPeter Thiel is an American entrepreneur and investor, a co-founder of PayPal and Palantir Technologies, and the first outside investor in Facebook.

The article describes Mach as taking “a hardware-first approach to defense” with new hydrogen creation and combustion techniques, building a suite of oxyhydrogen defense platforms including unmanned aerial vehicles and aerial protection devices, with the aim of solving hypersonic defense; it states that hydrogen can be manufactured in the field, is interchangeable across Mach’s systems, and improves projectile range and power as well as aerial loiter time and speed.[11]
The seed round was $5.7 million, with participation from Marque VC and Champion Hill Ventures; TechCrunch wrote in 2025 that it was announced in June 2023 and led by Sequoia Capital’s Stephanie Zhan and Shaun Maguire, and the Orange County Business Journal also states that Sequoia Capital led it, while Forbes describes it as a $5 million seed round co-led by Shaun Maguire. He was 19 at the time. Fortune writes that Stephanie Zhan, the Sequoia Capital partner who led the investment, said, “Ethan is a force of nature.”[8][10][14][6][2]
July 2023The Plan to Replace Gunpowder with Hydrogen
In July 2023 Mach Industries was developing hydrogen-powered unmanned aerial vehicles, munitions and hydrogen generation systems, betting that combustion of hydrogen produced in the field would give the U.S. military an edge against near-peer adversaries. On LinkedInLinkedInLinkedIn is a social networking platform for professionals. It was founded in 2002 by Reid Hoffman and others, launched in 2003, and listed on the New York Stock Exchange in 2011; after Microsoft acquired it for approximately $26.2 billion in 2016, it became a wholly owned Microsoft subsidiary. Its revenue comes from membership subscriptions, advertising, and recruitment solutions.Open the full entry he wrote that the company was “working to replace gunpowder”; he wanted munitions to be more like bullets than missiles, saying that “every time you do that, you really, really decrease your costs.”[8]
At the time the company had about 15 full-time employees, with its headquarters in Austin and offices in Boston; Boston handled engineering, while Texas was where hydrogen was tested in kinetic and combustion applications. The seed funding was to go to engineering, manufacturing, research and development and hiring; he hoped that within five years Mach would make thousands of products a year, with some systems reaching end users within 12 months.[8]
October 2023Bedrock Capital Leads a $79 Million Series A
In October 2023 Geoff Lewis, the founder of Bedrock Capital, led Mach Industries’ $79 million Series A. Forbes writes that the round valued the company at more than $300 million, and the Orange County Business Journal gave $335 million in 2024; the same paper’s 2025 OC50 profile describes the Series A as an $84.1 million round led by Bedrock Capital and Sequoia Capital, with valuations at the time cited as between $251 million and $335 million.[10][6][14][18]
2024Named to Forbes 30 Under 30
Early 2024The Hydrogen Team Is Spun Off and Mach Turns to Viper
About three months after the Series A, Erik Limpaecher announced on LinkedIn that he was leaving to start a new company, taking the team, technology, prototypes, customer relationships and revenue with him. Thornton said, “Early this year we decided to spin this team off of Mach,” and Limpaecher said that he was glad Ethan supported their plans.[6]
Forbes writes that the company had pitched Prometheus, a mobile hydrogen generator for the battlefield, which three former employees said was scrapped because Mach could not find a cost-effective way to produce the aluminum fuel it needed; in January 2024 the company pivoted to a drone called Viper, for which internal documents projected $850,000 in revenue that year, and Viper was later redesigned as a cruise missile that he said would cost less than 25% of current products.[6]
April 2024Headquarters Moves to Huntington Beach, California
In April 2024 Mach Industries moved its base to Orange County, CaliforniaCaliforniaCalifornia is a U.S. state on the Pacific coast; its capital is Sacramento and its largest city is Los Angeles. California was admitted to the Union on September 9, 1850, as the 31st state.

The company’s LinkedIn page listed Huntington Beach as its headquarters and his own LinkedIn profile cited Huntington Beach (Surf City) as his base, and job postings indicated that drone flight testing would take place mainly in the Mojave Desert.[14]
In a note on the company website dated May 18, 2024, he wrote that after closing the Series A in October 2023 the company moved to Huntington Beach to be closer to top technical talent and to scale better; he said that Orange County was more costly but “incredibly beneficial” for access to talent, that the company still operated in Texas, and that “We’ll look to mass manufacture somewhere near Texas most likely.”[3]
May 2024Forbes Publishes a Critical Investigation
In May 2024 Forbes published an investigation by David Jeans titled “Investors gave a teenager $85 million to build hydrogen weapons. It’s not going well.” Forbes interviewed nine current and former Mach employees and compared Mach’s hydrogen-powered firearms to “pneumatic potato cannons.”[6]
Eric McManus, a former program manager and U.S. Navy veteran who left the company in 2023, criticized Mach for raising so much money so soon without any real product, a flight test or a demonstration. Three former employees said that during a jet propulsion test in 2023 he tried to hold a drone down with his hands at full throttle to steady it for launch, that the drone could have tipped over and become a projectile, endangering everyone on the test range, and that range administrators shut the test down.[6]
The article states that a television in the main foyer of the Austin headquarters displayed a timer called “Time until Taiwan Invasion,” which a photo showed at about 1,800 days, and that McManus, who said he had been in the Taiwan Strait during civil unrest in 2008, found the timer “very offensive.” At a team meeting he compared Mach’s hierarchy to that of a cult (leader, clergy, priests, community leaders, true believers); a photo of a whiteboard showed the words “What Is A Cult?”, and employees were perplexed by the analogy.[6]
He declined to answer Forbes’s detailed questions and instead published a blog post addressing some of the issues, writing that he wanted to help national security and was concerned about America’s ability to fight a major war, and that “Between investors and recruits, I received far more traction than I expected”; he also wrote that 15 months earlier he had been working from a dorm room and now worked from a 115,000-square-foot factory, that the company had used 15% of the money it had raised, and that it had 45 employees. Bedrock Capital and Sequoia Capital did not respond to requests for comment.[6]
In an interview with the Orange County Business Journal in June 2024 he said that the Forbes article did not fairly portray the company’s work; in a note on the company website he described Mach as a one-year-old business that had “made many mistakes” and was working to fix them and learn from them.[3]
June 2024In the New Building in Huntington Beach
In June 2024, at 20, he and about 50 colleagues were working in a new 115,000-square-foot industrial building in Huntington Beach; after its $79 million Series A and $5.7 million seed round the company was valued at $335 million and was focused on two products, Viper, a drone-like miniature fighter, and a high-altitude weapons platform. He said hydrogen was “a fuel for some of the stuff we do,” including balloons; the company expected to reach about 100 employees by the end of the year and had no new funding round planned, and he called Mach “a manufacturing company more than anything else.”[3]
He said the path ahead would be “very hard” but that he had time to succeed; he said he faced no discrimination over his age from investors or customers — “The customer just cares about the technology” — and that building a team that could scale from “50 people to 5,000 people” in a couple of years was a challenge. He said he respected Palmer LuckeyPalmer LuckeyPalmer Luckey (born September 19, 1992) is an American inventor and entrepreneur.

March 4, 2025Army Contract for Strategic Strike Announced
On March 4, 2025, Mach Industries announced that the U.S. Army’s Army Applications Laboratory had selected it to develop Strategic Strike, a vertical-takeoff cruise missile meant to give maneuver units precision strike capability; the contract was awarded in the third quarter of 2024, the design was locked by the end of September 2024, and by mid-January 2025 the missile had transitioned from vertical takeoff to full-performance wingborne flight. The release gives a range of 290 km and a warhead of more than 10 kg. He said the team had taken Strategic Strike “from design kickoff in September to flight just 14 weeks later.”[21]
The same day, at 21, he described the company’s first factory, Forge 1, a 115,000-square-foot plant at its Huntington Beach headquarters and the first of many planned “decentralized” factories: “Instead of very centralized factories, we will build many, many smaller factories.” The plant was already building Viper, a light jet-powered vertical-takeoff drone that needs no runway and that Mach says costs up to 300 times less than traditional drones, and Glide, a bomb released from a vehicle at the edge of space. He said the factory could eventually produce 1,000 Vipers and 3,000 Glides a month.

In the release he said, “Mach Industries exists to enhance national readiness and preserve America’s strategic edge,” adding that global security depends on America’s ability to create asymmetric unmanned capability. Keith Rabois said Mach’s model was “purpose-built for the realities of modern conflict.”[15][22]
At the time Mach’s three main systems were Viper, a jet-powered vertical-takeoff cruise missile with a range of 180 miles and a warhead of more than 22 pounds, designed to launch from beyond enemy radar range; Glide, a high-altitude glider that can strike targets from miles away; and Stratos, a large sensor and communications balloon that can stay at extreme altitudes for several months.

Micky MalkaMicky MalkaMicky Malka (Meyer Malka in securities filings) is the founder and managing partner of the venture capital firm Ribbit Capital and earlier co-founded brokerage, banking and payments companies in Venezuela, Brazil and the United States; the Forbes Midas List has included him six times since 2021.Open the full entry, the founder of Ribbit Capital, praised him and the team for building with urgency and controlling their supply chain more closely.[31][30]
By then the company had grown from about 12 employees in its first year to about 350, with five autonomous vehicles in development — Viper, Glide, Stratos, Dart and Pike, a system for launching long-range munitions; the company’s release says production of at least three of them was expected to begin that year, while TechCrunch gives the following year. He expected four new production facilities by the end of 2026, declined to disclose revenue and said the business was split evenly between government and commercial customers. He recalled that two years earlier all-hands meetings had been held in a conference room with about 12 people, while the two-year party had more than 200 chairs and was standing room only; he said he was proudest of the speed of product development: “we went from no team to building a team to a jet engine firing in about eight months.”[30][31]
June 16, 2026A Defense Innovation Unit Contract for RIMES
On June 16, 2026, Mach Industries announced a Defense Innovation Unit contract for the Runway Independent Maritime Expeditionary Strike (RIMES) program, to develop an unmanned aircraft for the U.S. Navy that can carry out long-range strikes from surface combatants or expeditionary locations; Mach is the aircraft integrator and is working with Whisper Aero on Atlas, a hybrid-electric aircraft that carries a 1,000-pound payload over 1,400 nautical miles without a runway. The release states that Mach was flying five platforms, had manufactured more than 250 aircraft and had designed more than 1,000 solid rocket motors. TechCrunch’s June 21 article describes the aircraft as 40 feet long and about 4,000 pounds, taking off near-vertically and flying more than 1,000 miles.[32][1]
June 21, 2026TechCrunch Publishes His StrictlyVC Interview in Los Angeles
On June 21, 2026, TechCrunch editor-in-chief Connie LoizosConnie LoizosConnie Loizos is a technology journalist, founder of StrictlyVC and TechCrunch’s general manager and editor-in-chief since 2023.Open the full entry published her interview with him at a StrictlyVC event in Los Angeles. The article states that Mach was running six weapons programs at once, had raised about $485 million in total and had won about 13 government contracts, most of them past initial design and into government range testing, though none was in full-rate production; his goal was to move three of the programs into rate manufacturing by the end of 2026. The company had built and fired two jet engines from scratch in about eight months, and selling components accounted for about half of its revenue.[1]
Asked about running so many programs at once, he said, “It’s very hard,” but argued that defense is “a chess game you’re playing with an adversary” in which choosing only one product means you have already lost. He described Anduril Industries’ approach as “top-down, starting with the software stack” and Mach’s as “bottom-up, starting from the hardware stack,” and said he respected Palmer Luckey and that they were “on the same team.”[1]
He said the hardest challenge changes about every six months, from engineering to sales and now manufacturing at scale; he protects four or five hours a day to think and “war game the future,” sometimes pulling colleagues in to join him, which can “kind of frustrate them sometimes.” He said the most valuable pushback comes from employees doing the work, and that at regular companywide forums, an idea of his chief operating officer, he will “basically stand up there for like an hour” taking “the most aggressive possible questions” from employees.[1]
August 2026Interview with the Orange County Business Journal
An interview published on August 10, 2026, states that at 22 he had raised $500 million for the company and that Mach ranked No. 16 on the paper’s annual list of Orange County aerospace and defense companies, with 435 employees, 400 of them in Orange County; he said the company had made about 1,000 vehicles over the previous 12 months and that “We’ll be looking to at least 10x that over the next 12 months,” and “The big push is to get on full-rate production and start deploying our stuff on the battlefield,” adding, “We expect to raise more capital in the next year.”[26]
The article states that Mach was developing Atlas, a fixed-wing aircraft that takes off vertically from ships and remote locations, with Whisper Aero of Nashville, TennesseeTennesseeTennessee is a U.S. state in the southeast-central United States, with its capital at Nashville. It was admitted to the Union on June 1, 1796, as the 16th state, and the 2020 census (April 1, 2020) counted 6,910,840 residents.Open the full entry, which he saw as possibly having airline passenger uses in the long term, and that a June report from Fort Worth, Texas, said Mach had explored a $74 million manufacturing plant there that could support up to 1,000 jobs. He said that he had no mentor for dealing with investors and that his approach had always been “just to sit down and have a conversation,” and that he wore a suit for meetings in Washington but not for investors; he also said, “If you ever make money the optimization, things tend to fall apart.”[26]
September 10, 2026An Additional $600 Million at a $3.7 Billion Valuation
On September 10, 2026, Mach Industries announced a $600 million continuation of its Series C at a valuation of $3.7 billion, doubling in about three months and bringing the Series C to $900 million, with investors including Ribbit Capital, Infinite Capital, Bedrock Capital and Sequoia Capital. The money was to fund continued development of platforms in long-range strike, counter-drone and other mission areas and the expansion of manufacturing infrastructure. He said: “Modern deterrence requires an industrial base capable of building relevant capabilities.”[33][34]
A Fortune article on September 28 states that at 22 he was running a company with six weapons programs; he said private capital let Mach take risk earlier: “We’re building the product and the production capability at the same time.”[2]
October 8, 2026Selected for the Army’s PrSM Increment 4 Prototype
On October 8, 2026, Mach Industries announced that it was one of five companies to receive an Other Transaction Authority agreement for the U.S. Army’s Precision Strike Missile (PrSM) Increment 4, under which it will build on its Pike platform to develop a HIMARS-launched prototype able to engage moving maritime and relocatable land targets at ranges of more than 1,000 kilometers, with prototype development and flight testing beginning in fiscal year 2027. He said: “America needs long-range strike weapons that can be built in numbers and fielded fast,” and “We are proud to compete alongside the country’s most established weapons manufacturers.”[35]
As of November 2026: Founder and CEO of Mach Industries
As of November 2026 the leadership page of the Mach Industries website lists him as CEO and founder and states that his ultimate goal is to create “decentralized strategic capabilities” that guarantee the defense of freedom worldwide; the website states the company’s mission as developing and manufacturing asymmetric aerospace and defense systems and components by the millions to deter war and advance prosperity, its systems including Viper, Pike, Stratos, Glide, Dart and Atlas, and its production scaled through Forge, a network of decentralized, flexible factories.[7][36]
Views on Starting Out and Defense Manufacturing
Speaking to Fortune in 2026 about young founders, he said: “You’re never going to know everything, especially when you’re starting young, and you shouldn’t expect to,” and “If you wait until you have all the answers, you’ll probably never start”; he said the key lesson he had learned was knowing whom to surround himself with — “Find people who are better than you at the things you don’t know” — and urged young founders not to be afraid to fail: “Have conviction in the problem you’re trying to solve.”[2]
In a June 2026 interview he said, “I don’t think we’re going to out-manufacture China,” arguing that America’s strength lies in “creativity and productization” and that the real bottleneck is the supply chain for jet engines, solid rocket motors and radar: “The hard part is actually getting the stuff into the building.”[1]
