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.
ARRIS Composites is a Berkeley-based advanced manufacturing company that invented Additive Molding, a patented process for mass-producing continuous-fiber thermoplastic composite parts. The technology lets brands replace metal and plastic with lighter, stronger, more sustainable parts - and do it at consumer-electronics volumes.

Riley Reese is the CEO and co-founder of ARRIS Composites, a Berkeley-based advanced manufacturing company that invented Additive Molding - a patented process combining 3D printing and compression molding to produce continuous carbon-fiber composite parts at commercial scale. A materials scientist who once built biodegradable heart tissue scaffolds at UC Berkeley, Reese pivoted that same obsession with fiber architecture into a $157M-funded company whose technology now shows up in Brooks running shoes, Skydio drones, and bicycle spokes. He previously co-founded AREVO, worked at medical device giant Stryker, and led additive manufacturing programs in Amsterdam at TNO - before returning to Berkeley to tackle what he calls 'a new manufacturing category.'
