QuantumBlack, AI by McKinsey vs PwC: overview
QuantumBlack, AI by McKinsey
QuantumBlack began in 2009 as a performance-analytics unit for Formula 1 teams, joined McKinsey in December 2015 at roughly 45 people, and now runs McKinsey's AI and generative AI practice out of London across more than 40 offices worldwide, with a reported headcount in the 1,001-5,000 range. Its generative AI work spans large language model deployment, retrieval systems, and agentic workflows, framed with the same discipline the unit brought from motorsport: a claim isn't real until it's tied to a measured number.
PwC

The firm reports roughly 370,000 employees worldwide. Generative 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.
