PwC vs ITRex Group: overview
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.
ITRex Group
ITRex has been based in Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents. The agency pairs AI consulting with data analytics and cloud computing rather than offering strategy advice in isolation, which means clients get a partner who can assess data readiness before recommending an AI roadmap, not just a slide deck disconnected from technical reality.
