IBM Consulting vs Infosys: overview
IBM Consulting
IBM Consulting's roots run back to 1991, and it operates today out of Armonk, New York, with a global headcount near 160,000. Rebranded in 2021 from IBM Global Business Services, its AI service offering leans on IBM's own watsonx platform alongside decades of enterprise relationships. For a buyer already standardized on IBM infrastructure, that's a real service advantage; for one that isn't, it narrows the effective scope of what's on offer.
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 based in London, gives it a dedicated services arm distinct from the parent's much larger delivery organization.
