- **Entity Type**: Private (acquired by Naver Corporation in January 2023 for $1.2 billion; formerly public with ticker POSH on NASDAQ)

## Products & Services
- **[Poshmark Marketplace]**: A social marketplace app and website where users buy and sell new or used items across fashion, home, electronics, and beauty. Core features include "Posh Shows" (live selling events), "Closet Clear Out," and "Offer to Likers." It is a peer-to-peer platform with a strong community focus.
- **[Posh Protect]**: Buyer protection program that ensures items are as described or the buyer gets a refund.
- **[Posh Post]**: A simplified shipping service with flat-rate labeling for sellers.
