ISO - IN SEARCH OF is a buyer-led reverse fashion marketplace. The platform inverts the standard resale model by allowing buyers to post wanted ads for specific items, naming the exact piece, brand, size, colourway, condition, and the budget they are willing to pay. Sellers who own the requested item then respond directly with offers, rather than listing items into a general feed and waiting for buyers to find them. The service focuses on hard to find fashion, rare sneakers, niche watches, and collectibles that typically do not remain in stock for long. The core workflow consists of three steps. First, a buyer posts a search with detailed specifications and a price ceiling. Second, sellers who already own the item send offers against that search, eliminating the need for the buyer to browse through unrelated listings. Third, the buyer compares incoming offers, negotiates within a single conversation thread, and accepts the preferred offer to arrange shipping. All transactions occur directly between two members, and the platform provides a protection and safety guide that users are advised to read before completing their first deal. The platform serves two primary user groups. Buyers use it to locate archival fashion pieces, limited edition sneakers, and other items that are rarely available through conventional listings. Sellers use it to connect with individuals who have already expressed a committed intent to purchase, with a budget attached to the request. The open searches section allows visitors to view current demand on the platform without creating an account. The service is accessible through the website at iso-us.com.
