OfferUp is the largest mobile marketplace for local buyers and sellers in the United States, connecting more than 150 million people across communities nationwide. With over 150 million downloads and 30 million annual transactions, OfferUp has become one of the top 10 shopping apps by making it simple to buy and sell everything from cars and electronics to furniture and household items. The platform merged with Letgo in 2020 to create an even bigger marketplace, and has since expanded to include jobs, professional services, and home rentals.
Built as a mobile-first C2B2C marketplace with an emphasis on in-person transactions, OfferUp is on a mission to build the most trusted platform to buy, sell, connect, and engage in local life. The company's trust and safety measures include user profiles, ratings, and secure in-app messaging that protects personal information. Beyond its core marketplace, OfferUp offers business tools like Storefronts and Motors for sellers, partners with Thumbtack for local services, and integrates with SonicJobs for job listings. The company also publishes the annual Recommerce Report, providing insights into the growing secondhand economy.
