PROJECT GRANITE
A full marketplace built for vintage sports card collectors.
// built_for
Vintage sports card collectors, dealers, and consignors who need a marketplace that actually understands grading, sets, and provenance. The users are collectors listing cards and dealers running consignment inventory. They look for a dedicated platform when generic auctions force them to mislabel every listing.
// challenge
Generic auction sites didn't speak the language collectors use: grading, sets, provenance. Every listing had to be shoehorned into a generic title and description field, which made search and filtering useless. Buyers and sellers also had no shared vocabulary for condition and authenticity.
// approach
Listings, search, auctions, and seller tooling tuned for the category. Listings carry structured grade, set, and year fields so search and filters actually work for collectors. Listings and search shipped first, with timed auctions and seller consignment tooling following.
// outcome
Available for partnership and licensing in adjacent collectibles categories. Reach out for terms.
// why_it_matters
Collectors and dealers finally get a marketplace that speaks their language instead of forcing them to shoehorn cards into generic auction fields.
