Brennan Lieu is Co-Founder and CEO of Hybron Technologies, an advanced manufacturing company pioneering next-generation composite materials for aerospace, defense, and industrial systems.

Brennan studied Energy, Mechanical, and Aerospace Engineering at Stanford University, where he first began collaborating on advanced composite manufacturing with co-founder Aaron Guo.

Brennan brings deep composites expertise with skills spanning product development, patent drafting, and finite element analysis, and has been vocal about modernizing defense manufacturing processes that have gone unchanged for decades.

Prior to Hybron, Brennan served as Vice President of Product Development at AWA Composites and held engineering roles at Moog Aircraft, building a strong foundation in composite material innovation and aerospace manufacturing.

Hybron closed an oversubscribed $20M Series Seed round led by Marque Ventures, graduated from the Northrop Grumman Technology Accelerator, and produces composite components up to 90% lighter than aerospace-grade metals at 10-100x the speed of traditional manufacturing.
