Build this if
You have at least 20 vetted makers or vintage sellers ready to publish story-driven listings and a buyer audience that values provenance over price.
Curated marketplace where independent makers and vintage collectors publish listings with provenance, maker stories, and condition notes, while buyers discover items through editorial collections and trust signals.

Decision snapshot
You have at least 20 vetted makers or vintage sellers ready to publish story-driven listings and a buyer audience that values provenance over price.
Your sellers only need basic classified listings or your buyers expect mass-produced inventory with fast shipping.
Run a 4-week pilot with 20 sellers publishing 5 story-driven listings each; measure completed sales and repeat buyer rate against a control group on a generic marketplace.
Problem and target customer
Independent makers and vintage collectors lose sales on generic marketplaces because their items need provenance, condition notes, and maker backstory that standard product fields cannot express, so buyers hesitate to purchase higher-priced one-of-one goods.
Independent makers and vintage collectors selling handmade crafts, vintage collectibles, and small-batch goods who need a curated channel with story-driven listings and provenance tracking.
Curated marketplace with a transaction fee on completed sales plus a monthly subscription for sellers who want featured placement and unlimited listings.
Editorial note
Editorial collection pages curated by marketplace operators
Maker profile pages with bio, craft specialty, and provenance history
Provenance timeline component embedded in each listing detail page
