description: >-
  CDK Global is the dominant U.S. dealer management system (DMS) provider, serving roughly 15,000 automotive dealerships
  with software covering sales, F&I, fixed operations, parts, CRM, and digital retail. CDK was spun out of ADP in 2014
  and acquired by Brookfield Business Partners in July 2022 for $8.3B (taken private). The company operates the
  Fortellis platform — a developer marketplace and integration hub with 135+ published APIs, 425+ marketplace apps,
  82,000+ dealer integrations, and 6.7B+ API transactions per year — exposing CDK DMS data to ISVs, OEMs, and
  third-party automotive systems. CDK suffered a major BlackSuit ransomware attack on June 19, 2024, paying ~$25M in
  bitcoin to restore service over roughly two weeks; the outage caused an estimated $605M in dealer losses and triggered
  numerous lawsuits.
