Deloitte vs PwC: overview
Deloitte
Deloitte was founded in 1845 in London and is now the largest professional services network in the world by revenue and headcount, employing approximately 470,000 people as of 2025. Its AI and Insights practice covers generative AI, agentic AI, and edge intelligence, backed by the Deloitte AI Institute for research and thought leadership. At this scale, AI consulting is one service line within an enormous global professional services firm, not a dedicated boutique.
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.
