Layup Parts

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.
