QuantumBlack, AI by McKinsey vs PwC: overview

QuantumBlack, AI by McKinsey

QuantumBlack started in 2009 doing performance analytics for Formula 1 teams before McKinsey acquired it in December 2015, when it had around 45 people. It now operates as McKinsey's dedicated AI arm, headquartered in London with over 40 offices worldwide and a LinkedIn-reported headcount in the 1,001-5,000 band. The unit's origin in motorsport data science is unusual among AI consultancies and still shapes its emphasis on measurable performance gains rather than open-ended strategy decks.

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.
