Mach Industries closes $300M Series C, pursues six weapons programs

Mach Industries just raised $300 million in a Series C round that values the defense startup at $1.8 billion. That’s nearly four times the roughly $470 million valuation it carried after its Series B just one year earlier.

Inside the round

Infinite Capital and Ribbit Capital co-led the Series C, with Bedrock Capital, Sequoia Capital, and Khosla Ventures also participating. The round brings Mach’s total funding to over $485 million since its founding, a staggering sum for a company barely three and a half years old.

The previous Series B, a $100 million raise completed in June 2025, already signaled strong institutional appetite.

What Mach actually builds

Huntington Beach, California-based Mach Industries focuses on vertically integrated unmanned defense systems. It designs, manufactures, and assembles autonomous weapons platforms under one roof rather than relying on a sprawling network of subcontractors.

The company’s flagship products include the Viper, a vertical-takeoff strike vehicle; Glide, a high-altitude glider; and Stratos, an airborne platform. Six weapons programs are reportedly in development, spanning capabilities across these and other systems.

To bolster that approach, Mach acquired Exquadrum for $50 million in April 2026. Exquadrum specializes in propulsion and rocket systems, giving Mach in-house capabilities that most startups at its stage would have to outsource. The acquisition plugs directly into Mach’s manufacturing network, which the company calls the Forge.

The workforce has scaled to approximately 350 employees, reflecting an aggressive hiring push that aligns with the capital infusion.

The defense tech gold rush

The US Department of Defense is already a Mach customer, with contracts spanning the Army, Air Force, and Special Operations Command.

What this means for investors

There are no cryptocurrency, blockchain, or digital asset connections anywhere in Mach Industries’ operations, disclosures, or investor communications. This is a pure-play defense technology investment.

That matters for crypto-native investors watching capital allocation trends. When firms like Ribbit Capital, which backed some of the most consequential crypto companies of the last decade, start writing checks for autonomous weapons platforms, it signals a shift in where the risk-reward calculus looks most attractive to sophisticated capital allocators.
