Poshmark

One of the largest peer-to-peer social commerce resale platforms in North America, operating as a subsidiary of Naver Corporation

Poshmark is a social commerce platform that connects buyers and sellers of new and pre-owned clothing, accessories, home goods, and beauty products. Founded in 2011 and headquartered in Redwood City, California, Poshmark combines elements of social networking with e-commerce, allowing users to follow each other, share listings, and participate in virtual 'Posh Parties' — themed shopping events. The platform has grown to host tens of millions of users and hundreds of millions of listings, making it one of the largest resale marketplaces in North America. Poshmark went public on the Nasdaq in January 2021 under the ticker POSH, raising significant capital and validating the resale economy as a major retail category. In October 2022, South Korean internet giant Naver Corporation announced its acquisition of Poshmark for approximately $1.2 billion, a deal that closed in January 2023. Under Naver's ownership, Poshmark continues to operate as a distinct brand and platform, benefiting from Naver's technology expertise and global reach, particularly in Asian markets. Within the AdTech and retail media ecosystem, Poshmark is significant as a first-party data-rich marketplace with deep social engagement signals. The platform offers advertising and promotional tools for sellers and brands, including promoted listings and targeted visibility features. Its highly engaged community of fashion-forward consumers makes it an attractive channel for brands seeking to reach resale-minded, sustainability-conscious shoppers. Poshmark competes with platforms like Depop, ThredUp, Mercari, and eBay in the growing secondhand and recommerce market.
