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.
CollX
CollX is a Philadelphia-area startup whose mobile app lets collectors snap a photo of a sports or trading card and instantly identify it and see its current market value. Built around AI visual search trained on a database of more than 17 million cards, CollX has grown from a quick valuation tool into a full collection-management platform and peer-to-peer marketplace where over 3 million users scan, organize, price, buy, sell, and trade cards. The company monetizes through Pro and Gold subscriptions, marketplace commissions, and referral revenue from hobby partners like PSA, Whatnot, and Fanatics.
