SAN FRANCISCO, Aug. 30 /PRNewswire/ -- Online real estate broker Redfin Corporation today announced the opening of a San Francisco office for software engineers and real estate agents. Redfin will continue to run engineering and real estate operations from its Seattle headquarters, but opened the San Francisco office to support national expansion plans, and aggressive research and development hiring. Today, the office hosts three engineers and three real estate agents with capacity for a dozen people. The San Francisco office allows Redfin to draw on engineers from Silicon Valley as well as Seattle in its effort to build the industry's leading real estate e-commerce site. The office also provides a place for Redfin's Bay Area agents to meet clients with questions about buying or selling homes online. Redfin has experienced strong growth since expanding its Web site from Seattle to the Bay Area on May 31. Redfin hired Sasha Aickin, previously of Plumtree Software, to run the San Francisco development team, and promoted Rosemary Vo, previously of Century 21, to manage local real estate operations. "As part of its commitment to local service, Redfin will open a real estate office in all the major markets we serve," said Redfin CTO Brian Marsh. "But we have made an unusually deep investment in the Bay Area because the region is loaded with Internet-savvy real estate consumers, and great software engineers to boot." The office is located at 604 Mission Street in downtown San Francisco. About Redfin Redfin (www.redfin.com) is the real estate industry's first online brokerage.
