In 1987, Andrew C. Florance founded CoStar Group with a revolutionary vision: to digitize the world of commercial real estate. Having conceptualized the idea at Princeton University the previous year, Florance recognized that the commercial property industry was operating in the dark, devoid of comprehensive, verified data that professionals needed to make informed decisions. What began as a bold initiative to bring transparency to an opaque industry has evolved into the global standard for real estate information and analytics.
Today, CoStar Group stands as a S&P 500 and NASDAQ 100 company, leading the digital transformation of real estate worldwide. Through strategic acquisitions of innovative platforms like Apartments.com, LoopNet, Matterport, Homes.com, and AcreValue, CoStar has built an ecosystem that serves every segment of the real estate market - from commercial and residential properties to land and rural real estate. With over 6,500 employees across 14 countries, the company processes data on more than 5.9 million properties, empowering millions of professionals to discover properties, gain insights, and make smarter decisions that improve their businesses and lives.
