About the Company

Vinted

C2C marketplace for pre-owned fashion.

Vinted is an online marketplace where people buy and sell second-hand clothing and accessories. It operates as a consumer-to-consumer (C2C) platform that lets individuals list pre-owned items for sale and others purchase them. Revenue comes mainly from a Buyer Protection fee charged on each transaction, which covers customer support, shipping tracking, and refunds. The platform targets those interested in affordable, sustainable fashion and the circular economy, appealing to users who want to declutter, discover unique items, and shop more environmentally friendly. Vinted’s approach centers on peer-to-peer re-commerce, offering a simple way to trade clothing within a global community, with a focus on accessibility and sustainability rather than new-product manufacturing.
