IBM Consulting vs PwC: overview

IBM Consulting

IBM Consulting traces to 1991 and is headquartered in Armonk, New York, with roughly 160,000 employees globally. It was rebranded in 2021 from IBM Global Business Services, and its AI consulting work draws on IBM's own watsonx platform and decades of enterprise technology relationships. That platform tie-in is a genuine differentiator for clients already invested in IBM infrastructure, and a real constraint for clients who aren't.

PwC

PwC in its current form dates to a 1998 merger of Price Waterhouse (founded 1849) and Coopers & Lybrand (founded 1854), with global headquarters in London and a New York presence as well. The firm reports roughly 370,000 employees worldwide. AI consulting sits inside PwC's broader digital transformation and technology consulting practice rather than existing as a fully standalone unit, reflecting the firm's identity as a diversified professional services network first.
