‘For us, mobile is everything’, says Poshmark co-founder Tracy Sun

Poshmark co-founder Tracy Sun looks back on 2011, the year she and Manish Chandra launched their company, as if it was a different era.

“Instagram had just launched, no one really said ‘selfie,’” said Sun. “Not everyone owned a smartphone yet and people weren’t using them for everything they are today.”

Still, Sun and Chandra made a bet on mobile-only social commerce, a business model for its network of individual seller boutiques, where users can sell used and wholesale items. The business has expanded from a mobile reselling platform to a place where sellers can launch their own brands, or become wholesale partners on behalf of brands. As it’s expanded, it’s remained mobile-only.
