QuantumBlack, AI by McKinsey vs Cognizant: overview
QuantumBlack, AI by McKinsey
QuantumBlack started life in 2009 as a performance-analytics operation for Formula 1 racing teams before McKinsey folded it into the firm in December 2015, when the unit numbered around 45 people. Today it runs McKinsey's dedicated AI services out of London, across more than 40 global offices, with headcount reported in the 1,001-5,000 range. Its service catalog spans strategy, data engineering, and model deployment, with the motorsport origin still shaping how it frames results: specific numbers, not narrative claims.
Cognizant
Cognizant began in 1994 as an in-house technology unit inside Dun & Bradstreet in Chennai, India, and today runs out of Teaneck, New Jersey with roughly 349,800 employees. Its current AI Builder positioning frames its service catalog around bridging AI investment and enterprise value, a deliberate move away from an older IT-outsourcing identity, though the delivery model and scale still read as a large-scale IT services firm rather than a boutique AI practice.
