Buy-side sourcing for resellers

The brands are there.
ThredUp just didn't tag them.

ThredUp processes millions of garments. Thousands of designer pieces get listed as "unbranded" when tags are missed. ThreadSleuth scans those listings, identifies the real brand, and shows you what's actually worth buying.

How it works

From unbranded listing to confirmed flip in three steps

01
Scan Listings
ThreadSleuth monitors ThredUp's unbranded inventory in real time, pulling listings that show brand indicators in their photos.
02
Identify Brand
Photos are analyzed for RN numbers, care labels, and design signatures. Cross-referenced against the FTC database and brand catalogs.
03
Show the Flip
Only items with $100+ estimated resale value make the cut. You see the brand, the margin, and the ThredUp link. Buy before anyone else.
