QuantumBlack, AI by McKinsey vs PwC: overview
QuantumBlack, AI by McKinsey
Before it was McKinsey's AI practice, QuantumBlack was a performance-analytics operation for Formula 1 teams, founded in 2009. McKinsey acquired it in December 2015 when it had around 45 people; it now runs out of London with staff across more than 40 offices globally and a reported headcount in the 1,001-5,000 range. That racing pedigree still shapes how the practice pitches itself: outcomes measured in specific numbers, not narrative claims about transformation.
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 as well, and reports roughly 370,000 employees globally. Its AI advisory work lives inside a broader digital transformation and technology consulting practice rather than standing on its own, which fits PwC's identity as a diversified professional services firm first and an AI specialist second.
