The Problem
StockX · GOAT · Grailed
They authenticate and ship, but take a meaningful cut from every transaction. Sellers lose margin. Buyers pay more. Speed suffers.
Facebook Marketplace · Craigslist · OfferUp
They are free, but there is no trust infrastructure, no safety features, and no experience built for fashion. You are on your own.
Kolosseum exists in the space between these two. Better economics than the fee platforms. More trust than the local ones.
