Tradesy

Tradesy was a Los Angeles-based online marketplace for buying and selling pre-owned luxury and designer fashion, founded in 2009 and backed by 500 Global among others. In March 2022 it was acquired by Paris-based Vestiaire Collective to accelerate that company's expansion into the US resale market, and the standalone Tradesy brand was subsequently wound down. The tradesy.com domain now redirects to vestiairecollective.com, and Tradesy no longer operates an independent website, developer program, or public API. This profile is retained as a historical/acquired-company record.

Tradesy is profiled on the APIs.io network. Tagged areas include Company, Fashion, Resale, Marketplace, and Ecommerce.
