Buffalo Exchange
Buffalo Exchange is a family-owned resale fashion chain founded in Tucson, Arizona in 1974 that pioneered the buy-sell-trade model for secondhand clothing. Customers bring in gently used, on-trend clothing and accessories and receive cash or store trade on the spot, while shoppers browse a hand-picked mix of current styles, vintage finds and designer pieces at a fraction of retail. With roughly 40 stores across the United States and about 590 employees, Buffalo Exchange has built a business around affordable, sustainable style, keeping millions of garments in circulation each year and channeling small change into local charities through programs like Tokens for Bags.
Rebag
Rebag is a New York-based online and retail marketplace for buying and selling pre-owned luxury handbags, watches, jewelry and accessories. Founded in 2014 by Charles Gorra, the company built proprietary technology - most notably Clair, an appraisal index, and Clair AI image recognition - to standardize resale pricing and pay sellers upfront. It aims to bring transparency and liquidity to what it calls an opaque secondary luxury market.
Kintra Fibers
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
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.
unspun
unspun is a San Francisco-based fashion-technology company that built Vega, the world's first 3D weaving system for apparel. Vega weaves garments directly from yarn in minutes, skipping cut-and-sew steps to enable on-demand, near-zero-waste, locally produced clothing. A certified B Corp founded in 2015, unspun sells custom-fit jeans direct to consumers while licensing its hardware and software to brands and retailers aiming to decarbonize their supply chains. Its stated mission is to reduce global human carbon emissions by 1%.
Curtsy
Curtsy is a mobile-first, peer-to-peer resale marketplace where Gen Z and young millennial women buy and sell secondhand clothing, shoes and accessories. Founded in 2016 and originally a dress-rental service, it pivoted to resale and built its edge around making listing fast for casual sellers - using machine learning to suggest prices, fill in item details and estimate shipping weight, backed by human review. Sellers keep more of their money than on rival platforms (a ~19-20% commission), buyers save up to 70% on brands like Lululemon, Free People and SKIMS, and the app carries a 4.8-star rating across tens of thousands of reviews. Curtsy raised an $11M Series A led by Index Ventures in January 2021, part of $14.5M total funding.
Everywhere Apparel
Everywhere Apparel is a Los Angeles-based materials science company that turns textile waste into 100% recycled cotton clothing through its proprietary, GRS-certified CirCot fiber system. Founded in 2019 by three Stanford graduates, it sells blank and custom apparel to brands, bands, screen printers and uniform programs, and closes the loop with a free QR-code take-back program that recycles worn garments back into new products.
Indyx
Indyx is a San Francisco digital wardrobe app that lets people catalog everything they own, plan outfits, work with personal stylists, and eventually resell their clothes - all in one place. Founded by two former retail-industry insiders, it makes the opposite bet of most fashion businesses: instead of selling you the next thing, it helps you actually use what you already own. Users get a searchable digital closet with automatic background removal, cost-per-wear tracking, packing lists, and social sharing, framed around a simple idea - know what you own, love what you wear.
Another Tomorrow
Another Tomorrow is a New York-based luxury fashion company building timeless womenswear with a sustainability-first model. Founded by former Morgan Stanley managing director Vanessa Barboni Hallik, it pairs farm-level material traceability with a digital ID on every garment, enabling provenance tracking, anti-counterfeiting, and authenticated resale. It was the first luxury fashion brand to earn B Corp certification and frames its work around human, animal, and environmental welfare.
Revive | B-Corp Certified
Revive (stylized (Re)vive) is a New York fashion-tech company that turns returned, damaged, and excess apparel into recovered revenue for brands. Its AI-powered platform inspects each item in minutes to flag damage type and resale potential, then cleans, lightly repairs, and routes goods back to stores or onto resale channels - so unsellable inventory becomes profit instead of landfill. A Certified B Corp, Revive has recovered roughly $23M in gross merchandise value and kept over 150,000 garments out of landfills.
Cuyana
Cuyana is a San Francisco-based direct-to-consumer fashion company built on a two-word philosophy - Fewer, Better Things. Founded in 2011 by Karla Gallardo and Shilpa Shah, the brand makes premium leather goods, apparel, and travel essentials with sustainably-certified materials and an unusually long product lifespan. It runs a resale program (Revive), seven-plus retail stores, and ships globally.
