IBM Consulting vs KPMG: overview
IBM Consulting
IBM Consulting's roots go back to 1991, and it operates out of Armonk, New York with a global headcount around 160,000. Rebranded in 2021 from IBM Global Business Services, its AI advisory work is built around IBM's own watsonx platform and decades of enterprise account relationships. For a buyer already running IBM infrastructure, that tie-in is a real advantage; for a buyer who isn't, it's a real constraint worth weighing before shortlisting.
KPMG
KPMG was formed in 1987 by the merger of Peat Marwick International and Klynveld Main Goerdeler, though its roots trace back to 1897, and runs out of London today. Headcount estimates range between roughly 251,875 and 275,288 depending on the reporting period. Its AI service line includes named products, aIQ and Mystro, for AI transformation and digital labor optimization, more productized than some Big Four peers, though how much staff is specifically dedicated to AI hasn't been disclosed.
