IBM Consulting vs Infosys: 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.

Infosys

Infosys was founded in 1981 and is headquartered in Bengaluru, India, employing approximately 330,429 people worldwide as of March 2026. It runs a full suite of enterprise AI advisory services, and its wholly-owned subsidiary Infosys Consulting, founded in 2004 and headquartered in London, adds a dedicated strategy arm separate from the parent's much larger delivery organization.
