Amca reaches $1B valuation in 18 months and raises $300M to prove America's defence supply chain needs a complete rebuild — TFN

Amca has raised a $300M Series B led by Caffeinated Capital, pushing its valuation beyond $1B just 18 months after launch.

The startup is building an integrated aerospace and defence manufacturing platform that combines engineering, testing, documentation, and certified production into one system.

Its RAPID platform is already supporting production for major programmes, including the Lockheed Martin F-35 Lightning II, while helping cut development timelines by over 67%.

Eighteen months after launch, Amca has a unicorn valuation, a $300 million war chest, and a pointed argument: that America’s defence supply chain is not just struggling, it needs to be rebuilt from scratch.

The El Segundo, California-based startup has closed a $300 million Series B led by Caffeinated Capital, with Lightspeed Venture Partners joining existing backers Andreessen Horowitz, Lux Capital, Construct Capital, and House Capital. The round pushes Amca’s valuation beyond $1 billion, which the company claims makes it one of the fastest aerospace and defence startups to reach unicorn status.
