IBM Consulting vs KPMG: overview
IBM Consulting
IBM Consulting traces to 1991 and is headquartered in Armonk, New York, with roughly 160,000 employees globally. Its generative AI advisory work draws heavily on IBM's own watsonx platform and decades of enterprise technology relationships. That platform tie-in is a genuine advantage for clients already invested in IBM infrastructure, and a real constraint for clients who aren't, a trade-off worth weighing before any generative AI shortlist gets built.
KPMG
KPMG formed in 1987 from the merger of Peat Marwick International and Klynveld Main Goerdeler, with roots tracing back to 1897, and is headquartered in London. The firm employs roughly 251,875-275,288 people depending on the reporting period. Its AI services include named products such as aIQ and Mystro for AI transformation and digital labor optimization, giving it more named generative AI products than some Big Four peers, though details on staff specifically dedicated to generative AI weren't disclosed.
