QuantumBlack, AI by McKinsey vs Cognizant: 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.
Cognizant
Cognizant was founded in 1994 in Chennai, India as an in-house technology unit of Dun & Bradstreet, and is now headquartered in Teaneck, New Jersey with roughly 349,800 employees worldwide. The company describes itself as an AI Builder bridging AI investment and enterprise value, a repositioning aimed squarely at the generative AI wave, though the underlying delivery model and scale remain those of a large IT services firm, not a generative-AI-native boutique.
