Deloitte vs PwC: overview
Deloitte
Deloitte dates to 1845 in London and has grown into the largest professional services network in the world by both revenue and headcount, employing roughly 470,000 people as of 2025. Its AI and Insights practice spans generative AI, agentic AI, and edge intelligence, and it maintains a dedicated Deloitte AI Institute for research and thought leadership. At this scale, AI advisory is one service line inside an enormous global firm, not a purpose-built boutique agency.
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.
