IBM Consulting vs KPMG: overview
IBM Consulting
IBM Consulting's history runs back to 1991, and it operates today out of Armonk, New York, with a global headcount near 160,000. The 2021 rebrand from IBM Global Business Services signaled a shift in focus, and its AI work now leans heavily on IBM's own watsonx platform alongside decades of enterprise client relationships. For a company already standardized on IBM infrastructure, that's a genuine advantage; for one that isn't, it's a real limitation worth weighing before a shortlist gets built.
KPMG
KPMG formed in 1987 from the merger of Peat Marwick International and Klynveld Main Goerdeler, with a lineage tracing back to 1897, and runs today out of London. Headcount estimates land somewhere between roughly 251,875 and 275,288 depending on the reporting period cited. Its AI service line includes named products, aIQ and Mystro, aimed at AI transformation and digital labor optimization, which is more productized than most Big Four peers, though the firm hasn't disclosed how much staff sits specifically inside the AI practice.
