OfferUp operates a mobile-first marketplace connecting more than 150 million people across the United States to buy and sell goods and services locally. The platform facilitates roughly 30 million annual transactions across categories including vehicles, electronics, furniture, and household items, ranking among the top 10 shopping apps. The company merged with Letgo in 2020 to expand its reach.
The platform addresses the logistics of local commerce through secure in-app messaging, user verification systems, and tools designed to build trust between buyers and sellers. Business sellers can utilise Storefronts to present inventories, whilst the Motors product specialises in vehicle listings. OfferUp has expanded beyond goods sales through partnerships with Thumbtack for local professional services and SonicJobs for job listings integrated into its ecosystem.
OfferUp publishes an annual Recommerce Report tracking trends in the secondhand economy, signalling investment in market research and industry analysis. The company's focus centres on facilitating in-person transactions within local communities rather than shipping-based e-commerce, distinguishing its model from traditional online marketplaces.
