IBM Consulting vs Accenture: 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.

Accenture

Accenture was founded in 1989 and is headquartered in Dublin, Ireland, employing approximately 793,587 people worldwide as of March 2026. The firm reports having scaled its generative AI practice to more than 60,000 trained practitioners, delivering generative AI transformation engagements across financial services, healthcare, manufacturing, and consumer goods. At this scale, generative AI consulting sits within a vastly larger global consulting business.
