What is ThredUp?

ThredUp describes itself as an online resale platform for apparel, shoes and accessories, with a stated mission of getting consumers to shop secondhand first. It is headquartered in Oakland, California, and listed on Nasdaq and on the Long Term Stock Exchange under the ticker TDUP.

History

ThredUp was founded in 2009 by James Reinhart, Chris Homer and Oliver Lubin. Reinhart, a co-founder, is chief executive according to the company's investor relations page.

Business model and distribution

The consumer business works in two directions. Sellers receive a Clean Out Kit, send in items and are paid in cash, store credit or a charity donation. Buyers browse and purchase the secondhand items online. ThredUp sorts and evaluates items in distribution centres in the United States and Europe.

A second, business to business line offers resale as a service. Brands provide kits to their own customers, who return used items in exchange for in store credit with that brand.

ThredUp and technology

Wikipedia cites a June 2024 report that ThredUp added a board member and planned an expansion of its use of AI, but gives no further detail. The company's specific technology stack is not documented in the sources consulted.

Why it matters

ThredUp is a leading example of the shift of resale from charity shops to scaled, operations driven online marketplaces, and its brand partnerships show how resale is becoming part of mainstream retail strategy.
