Amca, El Segundo-based defense company, announced in late May it raised $300 million in series B funding, launching the critical components manufacturer into unicorn status with a valuation of more than $1 billion.
Founded in 2024, Amca received the fresh funding from repeat investor Caffeinated Capital, which led the round. Additional investment came from Lightspeed Venture Partners, Lux Capital, Andreessen Horowitz, Lux Capital and Construct Capital.
Amca, named after Advanced Manufacturing Company of America, is another in a long line of Southern California companies using software and artificial intelligence to update the manufacturing pipeline. The startup builds hardware for aerospace and defense use cases, like hydraulics, electronics and spaceflight components. In El Segundo, Amca operates a prototyping testing facility. In the span of a year, Amca has grown to operate six factories in California, New York and Iowa.
Together, the company oversees 123,000 square feet of production space, all of which is connected to Amca’s in-house AI product line called RAPID.
RAPID allows all parts of the manufacturing process – from designing, prototyping, testing and manufacturing – to sit in one workflow, making it easier for the company to move from one part of the manufacturing process to another.
The fundraise comes a year after the company secured $76.5 million in early-stage funding in April 2025. With that capital, Amca made its first acquisition – South El Monte-based Electro-Mech Components Inc.
Since then, Amca has made a handful of other acquisitions, such as Aerospace Control Products Inc., which focuses on hydraulics; Electrocube, a power electronics supplier for The Boeing Co.; and Payne Magnetics.
Amca also nabbed well-known customers like Boeing, Lockheed Martin Corp., Northrop Grumman Corp. and RTX Corp.
