Hybron Technologies, an advanced manufacturing company focused on next-generation composite materials, has secured participation from Veteran Ventures Capital as part of its oversubscribed $20 million Series Seed financing round led by Marque Ventures.
The investment was made through Veteran Ventures Capital’s Veterans Fund II and adds Hybron to a growing portfolio of dual-use technology companies, reinforcing the firm’s focus on scalable manufacturing solutions for aerospace and defense applications.
Founded in 2022 and headquartered in El Segundo, California, Hybron is developing proprietary composite manufacturing processes designed to significantly accelerate the production of high-performance structural components. Its hybrid chopped-fiber polymer technology enables complex parts to be produced up to 100 times faster than conventional composite methods while maintaining the strength and durability required for aerospace and defense use cases.
The company’s approach allows for the creation of lightweight components that can be up to 90% lighter than traditional aerospace-grade metals, while also lowering costs through a fully domestic supply chain. Hybron’s technology is designed to combine the strength characteristics of continuous carbon-fiber materials with the speed and scalability of chopped-fiber manufacturing.
Hybron was co-founded by Brennan Lieu, who serves as CEO, and Aaron Guo, the company’s Chief Technology Officer. The founders began collaborating on advanced composite manufacturing during their engineering studies at Stanford University and UC Berkeley. Their prior experience includes roles at AWA Composites, Moog Aircraft, Boeing, and AWA Forged Composites.
The company’s initial product pipeline includes composite 155mm artillery shell casings and turbine fan blades, both currently in advanced prototyping. The platform is designed to support large-scale domestic production of critical components for aerospace, defense, and industrial markets.
The investment comes amid growing global demand for munitions and defense systems, which has exposed limitations in Western manufacturing capacity. U.S. defense priorities increasingly emphasize expanding domestic production capabilities and strengthening supply chains for critical technologies.
Hybron plans to use the funding to continue engineering development and expand its manufacturing capabilities as it moves toward initial munitions production and broader commercialization.
KEY QUOTES
“Defense readiness increasingly depends on how quickly we can scale manufacturing. Hybron is tackling one of the hardest upstream problems in defense technology—how to produce high-performance structural components at the speed and scale modern conflicts demand. Their manufacturing platform has the potential to fundamentally change the economics of producing critical systems by compressing cycle times from weeks to hours without sacrificing strength of maintaining performance. As a firm built by operators who have seen firsthand how supply chain constraints affect readiness, Veteran Ventures invests in technologies that can close the gap between what the warfighter needs and what industry can deliver. Hybron is exactly that kind of company.”
Steve Kiser, General Partner, Veteran Ventures Capital
“Modern aerospace and defense systems are still built around manufacturing processes that haven’t fundamentally changed in decades. Our goal is to make advanced composites manufacturable at industrial scale so critical systems can be built faster, lighter, and more efficiently. Veteran Ventures Capital understands both the technology and the mission, and we’re excited to partner with them as we scale.”
