About Opendoor

Founded in 2014, Opendoor's mission is to empower everyone with the freedom to move.

We have assembled a dedicated team with diverse backgrounds to support more than 100,000 homes bought and sold with us and the customers who have selected Opendoor as a trusted partner in handling one of their largest financial transactions.
