QuantumBlack, AI by McKinsey vs Cognizant: overview
QuantumBlack, AI by McKinsey
QuantumBlack began in 2009 as a performance-analytics agency for Formula 1 teams, then joined McKinsey in December 2015 at roughly 45 people. It has since grown into McKinsey's dedicated AI agency, run out of London with more than 40 offices worldwide and a LinkedIn-reported headcount in the 1,001-5,000 range. Few agencies on this list can point to a motorsport pedigree, and it still shows in how the practice talks about performance gains: specific, measured, and tied to a number rather than a narrative.
Cognizant
Cognizant started in 1994 in Chennai, India as an in-house technology unit inside Dun & Bradstreet, and today runs out of Teaneck, New Jersey with roughly 349,800 employees. It now brands itself an AI Builder, positioned as the bridge between AI investment and enterprise value, a deliberate shift from its older IT-outsourcing identity, even though the underlying delivery model and scale still read as a large IT services firm rather than a boutique AI agency.
