Amca hits $1B+ valuation with $300M Series B for defence supply chain
What's the deal? Amca, an El Segundo, California-based startup that engineers and manufactures critical aerospace and defence components, has closed a $300M Series B at a valuation exceeding $1B — crossing the unicorn threshold just 18 months after its founding.

Why now? Growing geopolitical instability has exposed deep weaknesses in America's legacy defence supply chain — declining capacity, ballooning lead times, and an ageing workforce. The US military faces readiness-related shortages, and traditional manufacturers increasingly struggle to deliver at the speed and scale required.
Since launching, Amca has scaled to six factories across California, Iowa, and New York, operating over 123,000 square feet of qualified production capacity spanning hydraulics, avionics, power electronics, and more.

What could go wrong? Defence manufacturing is a notoriously complex business, governed by strict certification requirements and long qualification cycles. Scaling quickly through acquisitions while integrating new software infrastructure across multiple factories carries significant execution risk. And as a fresh unicorn with $1B+ valuation reached in just 18 months, expectations are steep.
The signal: Amca's rapid ascent to unicorn status reflects a broader wave of venture capital flowing into defence-tech and industrial reshoring. As geopolitical tensions persist, investors are betting that the US defence supply chain needs not just incremental fixes but entirely new platforms.
The company is deploying RAPID, its AI-powered product development system, which it says cuts the time from development to deployment by over 67% compared to industry norms. If that holds, it could set a template for how software-driven approaches modernise some of America's oldest and most critical industries.
