Redfin

One of the largest technology-driven real estate brokerages in the US, with significant digital marketplace and advertising capabilities through its RentPath acquisition

Redfin is a Seattle-based real estate technology company and brokerage founded in 2004. It operates a consumer-facing platform that combines MLS listing data, proprietary home valuation tools, and salaried real estate agents to offer a full-service home buying and selling experience at lower commission rates than traditional brokerages. Redfin's platform is known for its detailed property search, neighborhood data, and market analytics tools that attract millions of monthly visitors. In the AdTech and digital marketing context, Redfin has made strategic acquisitions to bolster its digital advertising and lead generation capabilities. The company acquired RentPath in 2021, a digital marketplace for apartment listings and rental advertising, which brought significant AdTech-adjacent capabilities including display advertising, lead generation, and digital marketing services for multifamily property owners and managers. This acquisition positioned Redfin more broadly in the real estate digital media and advertising ecosystem. Redfin went public on the NASDAQ in 2017 and has grown to become one of the most visited real estate websites in the United States. It competes with Zillow, Realtor.com, and traditional brokerages. While primarily a real estate brokerage and marketplace, its digital advertising infrastructure, programmatic display capabilities, and lead generation products for landlords and property managers place it at the intersection of real estate and AdTech.
