Denim is one of the many products sold on Poshmark, but it is one that is holding a greater role in the resale marketplace’s success.

At the heart of that success is Tracy Sun, who co-founded the company in 2011. Poshmark has since raised $160 million and has been valued at $1.25 billion. It boasts 60 million members.

Made to last, denim is a perfect fit for what Poshmark embodies, with the company looking to encourage the resale of pre-worn clothing, both increasing a garment’s life span and eliminating waste.

Sellers from mid-March through mid-June shared 60 million listings daily, doubling from 30 million prior to Covid-19. Since May, Poshmark saw a 50 percent increase in listings and orders, and a 40 percent uptick in new sellers year-over-year.
