QuantumBlack, AI by McKinsey vs Cognizant: 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.
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 positioning as an AI Builder, bridging AI investment and enterprise value, reflects 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 agency.
