From the very beginning, OfferUp has believed that the right people united by the right mission can redefine the possible.

OfferUp is now the largest mobile marketplace for local buyers and sellers in the US. We connect millions of people every day, but we’re still as committed as ever to the founding mission: to build the simplest, most trustworthy local marketplace. We help bring people together in their communities to exchange value, and we think that exchange is the foundation for a kind of commerce that redefines what “value” really means. In our world, the things we buy and sell are just the primer for the really important stuff, like meeting our neighbors, getting more connected to the places we live and the things that live with us, and creating a marketplace where everyone has something to offer.
