Manish Chandra had already built and sold a company before starting Poshmark. His previous venture, Kaboodle (a social shopping site), was acquired by Hearst in 2007. But Chandra saw a bigger opportunity: the closets of America were full of clothes people no longer wore, and there was no easy, social way to sell them.

The Closet Economy

Poshmark launched in December 2011 as an iOS app focused exclusively on women's fashion resale. The thesis was simple but bold: people would sell clothes from their closets if the process was as easy as taking a photo and posting to social media.

The early days were all about supply. Chandra and his co-founders — Tracy Sun, Gautam Golwala, and Chetan Pungaliya — personally onboarded early sellers, teaching them how to photograph and list items. They handled shipping logistics by providing pre-paid shipping labels, removing the biggest friction point in peer-to-peer commerce.

Posh Parties: The Social Commerce Breakthrough

The breakthrough came with Posh Parties — virtual shopping events themed around categories like "Best in Tops" or "Luxury Closet." During a Posh Party, sellers would share their listings to the party feed, and buyers would browse themed collections in real time. These weren't just shopping events — they were social gatherings.

At peak, Poshmark hosted multiple Posh Parties daily, each attracting tens of thousands of participants.

The Flywheel: Sellers as Marketers

Poshmark's genius was turning sellers into marketers. Every seller had a financial incentive to share their listings widely and engage with other users. The platform gamified engagement — sellers earned "Posh Ambassador" status by sharing, following, and selling.

• More sellers → more inventory → more buyers → more sales → more sellers

By 2013, the flywheel was spinning. Poshmark was processing thousands of orders daily without significant marketing spend.

Scaling to IPO

Poshmark expanded from women's fashion to men's, kids, home, pets, and electronics. The 20% commission model (on sales over $15) proved highly profitable at scale.
