PwC vs ITRex Group: overview
PwC
PwC in its current form traces to a 1998 merger of Price Waterhouse (founded 1849) and Coopers & Lybrand (founded 1854), headquartered in London with a major New York presence too, and reports roughly 370,000 employees globally. Its AI service offering lives inside a broader digital transformation and technology consulting practice rather than standing on its own, consistent with PwC's identity as a diversified professional services firm first, an AI specialist second.
ITRex Group
ITRex has operated out of Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents. The agency deliberately bundles AI advisory with data analytics and cloud computing services rather than offering strategy in isolation, checking whether a client's data infrastructure can actually support the roadmap before recommending one.
