Kintra Fibers is a Brooklyn-based materials science company developing a bio-based, biodegradable alternative to conventional polyester. Built on polybutylene succinate (PBS) derived from plant sugars rather than fossil fuels, Kintra's yarn performs like standard polyester and runs on existing melt-spinning equipment, but composts in controlled conditions and sheds far less persistent microplastic. Founded in 2018 by Billy McCall and Alissa Baier-Lentz, the H&M Group-backed company has raised roughly $10M total and is piloting its fiber with brands including Inditex, BESTSELLER, Reformation and PANGAIA.
Simplifyber is a North Carolina biomaterials company reinventing how soft goods are made. Its proprietary natural-fiber liquid, Fybron, is injected into 3D molds to form fabric directly, skipping the spinning, weaving, cutting, and sewing steps of conventional textile production. Founded in 2021 by fashion veteran Maria Intscher-Owrang and Phil Cohen, the company targets fashion, footwear, bags, automotive and aviation interiors, and consumer packaging with a cellulose-based, largely biodegradable alternative to fossil-derived materials. It closed a $12M Series A led by Suzano Ventures in April 2025.
