Defense-Backed Startup Raises $42M to Digitize Composite Manufacturing Supply Chain

Layup Parts, founded by Anduril veteran Zack Eakin, closed a $42 million Series A led by Founders Fund in June 2026. The Huntington Beach startup aims to build a marketplace for carbon fiber and advanced composite parts, targeting a supply chain historically fragmented across specialized job shops. The funding follows a $9 million round just five months after the January 2024 founding, signaling investor confidence in applying digital marketplace models to a sector with strict aerospace and defense quality requirements.
