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), headquartered in London with a major presence in New York as well. The firm reports roughly 370,000 employees globally. Its AI advisory work sits inside PwC's broader digital transformation and technology consulting practice rather than existing as a fully independent unit, a reflection of PwC's identity as a diversified professional services firm first, AI specialist second.
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.
