AvCarb Material Solutions
AvCarb Material Solutions is a Lowell, Massachusetts manufacturer of engineered carbon fiber materials - gas diffusion layers, felts, papers, woven fabrics and molded graphite laminates - built for the toughest electrochemical, thermal and friction jobs. With roots tracing to AVCO in the early 1960s (the same Lowell operation that helped develop Apollo's AVCOAT heat shield), AvCarb now supplies the carbon guts of hydrogen fuel cells, electrolyzers and redox flow batteries, alongside legacy work in automotive wet friction and even fishing-reel drag washers.
Industrial Microbes (iMicrobes)
Industrial Microbes (iMicrobes) is an Alameda, California synthetic-biology company that engineers programmable microbes to turn renewable, low-carbon feedstocks - primarily ethanol and methane - into drop-in chemicals and materials such as 100% bio-based acrylic acid, acrylonitrile and carbon fiber precursors. Founded in 2014, the company aims to give chemical producers and consumer brands a cost-competitive, lower-carbon alternative to petrochemicals, and has scaled its bioprocess to a pilot bioreactor producing 10+ kg per run.
Chris Holmes
Chris Holmes is the President and CEO of AvCarb Material Solutions, a Lowell, Massachusetts maker of engineered carbon materials - the felts, fabrics, and papers that quietly sit at the heart of hydrogen fuel cells, electrolyzers, and flow batteries. An MIT-trained systems engineer with a hybrid technical-and-business background, he is a turnaround specialist who has led high-technology businesses from start-up scale to north of $200M in revenue, largely inside private-equity portfolios. At AvCarb he is steering a company with 1960s roots toward the center of the clean-energy transition.
Noah Helman
Noah Helman is the co-founder and CEO of Industrial Microbes (iMicrobes), an Alameda, California synthetic biology company that engineers the central metabolism of microbes so they can eat cheap, renewable feedstocks - ethanol and methane - and spit out the chemicals normally pumped from petroleum. A Stanford applied-physics PhD who spent roughly a decade in physics labs before crossing into biology, Helman co-founded the company in 2014 with two fellow alumni of the biofuels startup LS9. iMicrobes targets drop-in, cost-competitive, net-zero versions of acrylic acid (for paints and adhesives) and acrylonitrile (for carbon fiber). The company went through Y Combinator's W15 batch, holds more than 20 patents, raised a $10M+ seed round in late 2024, and in 2025 announced it had scaled production of 100% bio-based, high-purity acrylic acid.
Impossible Objects, Inc.
Impossible Objects is a Northbrook, Illinois manufacturer of industrial 3D printers built around its proprietary CBAM (Composite-Based Additive Manufacturing) process. Instead of melting plastic filament, CBAM stacks long-fiber sheets of carbon fiber or fiberglass, inkjet-prints each layer with a fluid, bonds them with high-performance polymer powders like PEEK and nylon, then compresses and heats the stack into a solid composite part. The result is parts the company says are stronger, more dimensionally accurate, and printed up to 15x faster than competing methods - aimed at aerospace, defense, automotive, and electronics customers that need composite parts at production volume.
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.
Zack Eakin
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.
Specialized Bicycle Components
Specialized Bicycle Components is a Morgan Hill, California maker of high-performance bicycles, components and gear founded in 1974 by Mike Sinyard. It built the first mass-produced mountain bike, the 1981 Stumpjumper, and today designs road, mountain, gravel and Turbo e-bikes alongside helmets, apparel and the Retul fit system. With roughly 1,300 employees and an estimated $500M in revenue, it is one of America's 'Big Three' bike brands and a fixture in pro road, mountain and triathlon racing.
ARRIS Composites
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
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.'
