Amca announced a $300 million Series B to accelerate the development of America's new industrial base. Amca rapidly develops and manufactures critical aerospace and defense components by combining engineering, qualification testing, technical data development, and certified manufacturing capacity into a single integrated platform. The round was led by Amca's Series A lead, Caffeinated Capital, with major participation from Lightspeed Venture Partners and continued support from existing investors, including Andreessen Horowitz, Lux Capital, Construct Capital, and House Capital. With this financing, Amca is now valued at over $1 billion, eighteen months after its founding, making it one of the fastest-growing companies in aerospace and defense to reach this milestone.
