Poshmark was founded by Manish Chandra, Tracy Sun, Gautam Golwala, & Chetan Pungaliya in 2011. The company operates a mobile phone app which allows users to sell their gently used items and ship them to customers anywhere in the US.
Poshmark takes a 20% commission from items sold. Sellers can have their accounts suspended or completely removed from the site if they take sales offline or to a competitor. While some people have claimed to make several thousand dollars in a single month, (with one seller hitting $1 million in sales) others say that a lack of ratings or feedback from buyers leaves clients open to fraud.
Poshmark stated in August 2018 that sellers had made a combined income of $1 billion since the app was introduced.
Currently, the app is only for US users, but that might change in the future. Company headquarters are located in Redwood City, California.
