From Hydrogen Explosion to Defense Tech Pioneer: The Rise of Mach Industries
How a Teen Founder Turned Crisis Into Opportunity
At just 21 years old, Ethan Thornton has already made history as the founder behind Mach Industries — Sequoia Capital’s first-ever defense technology investment. Since its 2023 founding, the startup has raised over $80 million and caught the attention of major government contractors. But Thornton’s path to success wasn’t without explosive challenges.
The Incident That Changed Everything
Months before securing Sequoia’s seed investment in summer 2023, Mach Industries faced a critical setback:
- A hydrogen gun prototype catastrophically failed during testing
- The explosion sent shrapnel flying hundreds of feet
- One team member sustained injuries (as first reported by Forbes)
Thornton recently addressed the incident publicly for the first time during his April 3 appearance at StrictlyVC in San Francisco:
“At the time, we were trying to self-fund it, and we didn’t have the money to sort of run these procedures the way they should have been,” he admitted.
Pivoting With Purpose
The explosion became a turning point for the young company:
- Immediate shutdown: Mach halted all operations post-incident
- Safety overhaul: Established dedicated safety protocols and teams
- Strategic pivot: Moved away from volatile hydrogen technology
“Hydrogen was probably a bad tech bet that required further development,” Thornton conceded at the event.
From Crisis to Government Contracts
With Sequoia’s backing, Mach Industries has:
- Developed new weapons systems including:
- Advanced cruise missiles
- The “Glide” bomb (deployable from near-space altitudes)
- Secured a U.S. Army contract
- Announced plans for decentralized manufacturing facilities (“Forge” network)
Why Investors Are Betting Big
Thornton attributes Mach’s $85 million funding success to:
- Rapid prototyping capabilities
- Unique government collaboration approach
- Ability to translate innovations into official military programs
“It’s not necessarily my ability to build these things, but more so our ability to actually work with the federal government to get programs of record built around them,” Thornton explained.
The Road Ahead
From MIT dropout to defense tech wunderkind, Thornton’s journey proves that even catastrophic failures can fuel extraordinary comebacks. With major contracts secured and innovative weapons in development, Mach Industries represents a new generation of defense technology startups — ones that learn quickly, pivot strategically, and move at startup speed.
