Leading mobile-first local marketplace in the United States
OfferUp is a peer-to-peer mobile marketplace that enables users to buy and sell locally within their communities. Founded in 2011, the platform has grown to become one of the largest mobile marketplaces in the United States, competing directly with platforms like Craigslist, Facebook Marketplace, and Letgo (which it acquired and merged with in 2020). The platform focuses on creating a trusted, user-friendly experience for local commerce through features like user ratings, secure messaging, and identity verification. While OfferUp is primarily a marketplace platform rather than a pure AdTech company, it operates within the digital advertising ecosystem by offering promoted listings and advertising solutions for sellers looking to increase visibility of their items. The company generates revenue through transaction fees on shipped items, promoted listings, and premium features for sellers. OfferUp has facilitated billions of dollars in transactions and serves millions of users across the United States. The platform's advertising component allows sellers to boost their listings to reach more potential buyers, positioning it at the intersection of e-commerce and local advertising. OfferUp's mobile-first approach and focus on local communities differentiates it in the competitive online marketplace landscape.
