Layup Parts is a Huntington Beach, California company building a software-defined manufacturing platform for custom composite parts. Through its FiberPortal portal, engineers upload a 3D model, configure materials and ply layups, get an instant interactive quote, and receive finished carbon fiber or fiberglass parts - with quality documentation - in as little as two weeks. Founded in 2024 by former Anduril and Boring Company engineer Zack Eakin, the company pitches itself as the 'Amazon of composites,' automating the slow, quote-by-email world of composite fabrication for aerospace, defense, motorsports and high-tech customers. It raised a $42M Series A in June 2026 led by Marlinspike.
Zack Eakin is the co-founder and CEO of Layup Parts, a Huntington Beach startup that wants to make ordering custom carbon-fiber and fiberglass parts as easy as ordering from Amazon. A composites engineer who started in IndyCar bodywork at Chip Ganassi Racing, became the first engineer at Elon Musk's The Boring Company, and led mechanical engineering on Anduril's Roadrunner drone, Eakin launched Layup in 2024 to attack a problem he kept hitting himself: composite parts that take weeks and cost a fortune. With software-driven manufacturing and standardized stock materials, Layup compresses some jobs from weeks to hours. In June 2026 the company raised a $42 million Series A led by Marlinspike, on top of a $9 million seed from Founders Fund.
