Retrofit
Retrofit is an AI-curated vintage marketplace that uses AI agents to sift through hundreds of thousands of secondhand listings, analyzing social media trends, sales data and personal style to surface pieces matched to a shopper's taste, size and budget. Founded in 2024 by Sandra Lifshits and Maddy Yip and backed by Y Combinator (W25), it standardizes photography and descriptions from partner vintage stores so shoppers get a clean, personalized feed instead of endless digging.
Vendoo
Vendoo is a crosslisting and inventory-management platform for online resellers. From one dashboard, sellers post a single item to 10+ marketplaces - eBay, Poshmark, Etsy, Mercari, Depop, Facebook Marketplace, Grailed, Vinted and more - and the software handles the repetitive parts: detecting a sale and auto-delisting the item everywhere else, tracking inventory, sending offers, and calculating fees and profit. Founded in 2017 and part of Y Combinator's Winter 2022 batch, Vendoo says it serves more than 81,000 resellers who have created over 26 million listings on the platform.
Dagne Dover
Dagne Dover is a New York-based direct-to-consumer accessories brand founded in 2013 that designs hyper-functional bags - backpacks, totes, diaper bags, and luggage - engineered around organization and everyday problem-solving. Built by three women who bootstrapped rather than chasing venture capital, the brand is known for its signature neoprene 365 Collection, recycled Repreve linings, and an 'Almost Vintage' resale program that extends the life of its products.
Goodwill Industries International
Goodwill Industries International is the umbrella organization for a North American network of about 150 autonomous, community-based Goodwill nonprofits. Founded in Boston in 1902 by Methodist minister Edgar J. Helms, it runs the classic model of collecting donated clothing and household goods, reselling them through thrift stores and, increasingly, online, and using the proceeds to fund free job training, career services, and support programs. The parent body sets brand standards, coordinates national partnerships, and runs shared initiatives such as the online marketplace GoodwillFinds and the Goodwill Digital Career Accelerator, while local members deliver services on the ground.
Novelship
Novelship is a Singapore-based online marketplace for buying and selling authentic sneakers, streetwear, apparel and collectibles across Asia-Pacific. Founded in 2018, it connects buyers and sellers through a bid-and-ask model, verifies every item in-house before it ships, and has grown into one of the region's largest platforms for limited-edition drops from brands like Nike, Jordan, Adidas, New Balance and ASICS.
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.
Flyp
Flyp is a San Francisco software company that builds affordable, all-in-one tools for online resellers. Its Crosslister moves a single listing across Poshmark, eBay, Mercari, Depop, Etsy and Facebook Marketplace, while its Poshmark bot automates closet sharing, offers to likers, follow/unfollow and CAPTCHA solving. Founded in 2018 by James Kawas and Dani Arnaout, Flyp positions itself as the enterprise-grade toolkit for the roughly hundreds of thousands of 'power resellers' who move used goods for a living - at $9/month after a long free trial, undercutting rivals that charge $100+.
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.
EON
EON is a New York-based enterprise software company building the Digital ID layer for physical products. Through its EON Product Cloud platform, brands give each item a unique, traceable digital identity - accessed via QR code, NFC chip or RFID tag - that follows the product across its full lifecycle, powering resale, repair, authentication, customer engagement and compliance with the EU's upcoming Digital Product Passport regulation. Founded in 2017 by Natasha Franck, EON authored the open CircularID Protocol and works with brands including Coach, Chloe, H&M, Mulberry and Target.
eBay
eBay is one of the original internet marketplaces, a global platform where roughly 136 million buyers shop across hundreds of millions of listings in about 190 markets. Born in 1995 as a hobby site called AuctionWeb, it pioneered the idea that strangers could trust strangers enough to trade online. Three decades later it has reinvented itself around enthusiast categories, certified collectibles, and recommerce - selling the new, the rare, and the gloriously second-hand.
Archive
Archive is the technology platform behind brand-owned resale. It builds and operates customized secondhand storefronts for fashion and lifestyle brands - including The North Face, New Balance, Oscar de la Renta and Dr. Martens - so they can keep products in circulation, capture a new revenue stream, and meet customers who increasingly refuse to buy new.
Trove
Trove is the Oakland-based recommerce platform that powers branded resale and trade-in programs for retailers like Patagonia, Levi's, Lululemon, REI, Canada Goose, and Carhartt. Its software, operations, and AI-driven pricing engine turn used goods into a profitable new sales channel, helping brands extend product life and capture value from items already in customers' closets.
Vacatia
Vacatia is a hospitality company reinventing the timeshare experience. It runs a marketplace for buying, selling, and trading vacation ownership interests, and increasingly manages the resorts behind those interests - bringing modern booking technology and owner services to a category that hadn't seen much of either.
