Opendoor is an iBuyer that lets U.S. homeowners request a near-instant cash offer on their home, sell directly to Opendoor, list with Opendoor through its agent network, or browse off-market inventory via Opendoor Exclusives. Founded in 2014 and publicly traded on NASDAQ as OPEN, the company runs buying, renovation, listing, and resale at scale and partners with third-party agents and brokerages through its Opendoor for Agents program and Opendoor Exclusives marketplace. Opendoor does not publish a self-serve public developer portal or open REST API; partner and agent integrations are arranged directly through Opendoor's business development and partnerships teams. This profile documents what is publicly findable on Opendoor's partner-facing surfaces.
