IBM Consulting vs Accenture: 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.

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 scaling its generative AI practice to more than 60,000 trained practitioners, running AI transformation engagements across financial services, healthcare, manufacturing, and consumer goods. At this scale, AI advisory is a practice area inside a vastly larger global consulting business rather than the firm's identity.
