Definitive Healthcare Corp.
A data and analytics company focused on the business side of healthcare, Definitive Healthcare gathers and organizes information about hospitals, physicians, and other providers into a subscription platform that helps life-science firms, consultants, and others understand the market and find new customers. Founder Jason Krantz launched it in 2011 in Framingham, Massachusetts, after earlier building Infinata, a pharmaceutical-intelligence company he sold to the Financial Times Group in 2007. That earlier venture survived the dot-com bust of the late 1990s to be acquired—a start-up rarity that helped shape his next act.
