IBM Consulting vs Andersen: overview
IBM Consulting
IBM Consulting's history runs back to 1991, and it operates today out of Armonk, New York, with a global headcount near 160,000. The 2021 rebrand from IBM Global Business Services signaled a shift in focus, and its AI work now leans heavily on IBM's own watsonx platform alongside decades of enterprise client relationships. For a company already standardized on IBM infrastructure, that's a genuine advantage; for one that isn't, it's a real limitation worth weighing before a shortlist gets built.
Andersen
Andersen was founded in 2007 and is headquartered in Warsaw, Poland, running more than 3,500 specialists across 20 office locations and 16 development centers globally. Its named AI and data practice spans advisory, machine learning, data engineering, and robotic process integration, sitting on top of a broader stack that covers .NET, Java, Python, PHP, and Go. Its client industries run through financial services, healthcare, logistics, automotive, and media.
