ThredUp provides an online marketplace for the buying and selling of secondhand fashionwear, offering affordable prices on discount clothing whilst promising a regulated and consistent approach to quality and cleanliness standards. The company acquires its clothing through sellers sending packages of clothing, which the company then sifts through to decide what is sellable and what should be returned.

The company went public in 2021 and immediately acquired Remix, a European second-hand fashion outlet, as part of its international expansion plans. It has however struggled to achieve profitability thanks to global economic turmoil and a glut of new clothing in the fashion industry causing prices to drop sharply. It is focusing on reducing its operating costs and expanding its storage capacity, and is expected by analysts to weather the current conditions in good form.
