Overview:Redfin is a technology-powered real estate brokerage that represents people buying and selling homes. Founded and run by technologists, Redfin has a team of real estate agents who earn a salary and customer-satisfaction bonuses, not commissions. Redfin.com features all of the broker-listed homes for sale, as well as for-sale-by-owner properties. Redfin real estate agents work with the company's team of engineers to create tools that make the buying and selling process easier. As of October 2015, the company serves 80 major markets across the U.S. and has closed more than $20 billion in home sales. The service launched in February 2006. Redfin's main competitors include real estate search services like Trulia , Zillow , Estately and Realtor.com , and traditional real estate brokerages. None of their competitors combine online real estate search/technology tools and brokerage services. On their site, Redfin combines MLS listing information with historical data into a single map. Customers can search for homes by neighborhood, city, zip code, MLS number or school zone, and can refine results using detailed parameters like price and number of beds or baths. The company was founded by David Eraker and is based out of Seattle; there is also a San Francisco engineering office, and local agents in each of the markets Redfin serves.
