QuantumBlack, AI by McKinsey vs Cognizant: 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.

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, which reflects a shift from its historical IT outsourcing identity toward AI-specific positioning, though the underlying delivery model and scale remain those of a large IT services firm.
