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.'
