Refiberd

Refiberd develops AI-enabled textile material detection technology using hyperspectral imaging to identify fiber composition and contaminants in the textile supply chain. The company's proprietary system combines high-definition hyperspectral imaging with artificial intelligence to accurately detect fiber composition, including trace materials like spandex, nylon, and acrylic below 2% composition. This contact-free system enables millisecond detection speed per garment, addressing a critical industry need as brands lose $39B annually from materials being switched in production and recyclers suffer $7.5B in yield losses from bad feedstock. Founded in 2020 and headquartered in Cupertino, California, Refiberd has raised approximately $5.4M in seed funding. The company won eBay's 2025 Circular Fashion Fund award and differentiates itself by offering a fast, accurate, non-destructive methodology that surpasses traditional chemical analysis and digital product passports for textile material detection.
