CoStar Group

RANK27

Even when commercial real estate prices cratered during the 2008 financial crisis, CoStar, which provides analytics to the industry, remained resilient; its revenue dropped just 1% in 2009. The company’s tech-focused strategy is core to its stability. CoStar’s revenue has continued to rise despite the pandemic, as landlords with fresh vacancies crowd to its online marketplace, Apartments.com—helping push revenues in the third quarter to a new record of $426 million.
