The document outlines plans for a startup called Open Door that aims to provide instant liquidity for residential real estate by making the home selling process simple, certain and fast. The current residential real estate market is described as lengthy, expensive and bespoke. Open Door plans to use an automated online process to make cash offers on homes in as few as 3 days. The startup is seeking $9 million in Series A financing to build an accurate automated valuation model, acquire and sell homes to validate their model and economics, and acquire a large sample of sellers to validate the seller discount curve. Success would allow homeowners to move more freely and increase home ownership rates by reducing all friction associated with selling a home.
