Poshmark

Poshmark is a fashion resale marketplace founded in 2011 and operating in the United States and Canada. The platform connects buyers and sellers of secondhand fashion and other goods through a community-driven model built around real-time social experiences. Users sell items from their own closets and shop across more than 90 categories, from women's, men's and kids' clothing to home, electronics, pets, beauty, luxury and vintage goods.

The company's scale is substantial. Its community numbers more than 165 million members, and the platform has facilitated over $8 billion in seller earnings on more than 350 million items sold. Listings span upwards of 10,000 brands. The core product, Poshmark Marketplace, is delivered as a mobile-first application, reflecting the founders' original interest in the iPhone's potential to connect people through mobile technology.

Technical work at Poshmark centres on mobile technology, social commerce, marketplace infrastructure and real-time social features. The company was founded by Manish Chandra, Chetan Pungaliya, Gautam Golwala and Tracy Sun, and states a mission to put people at the heart of commerce, making online shopping and selling social and accessible. Its business model also has a sustainability dimension, keeping fashion in circulation for longer.
