IBM Consulting vs ITRex Group: 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.
ITRex Group
ITRex has run out of Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents. The agency pairs AI advisory with data analytics and cloud computing instead of offering strategy in isolation, meaning clients get a partner who checks data readiness before recommending a roadmap, not just a slide deck disconnected from what the client's systems can actually support.
