QuantumBlack, AI by McKinsey vs IBM Consulting: 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.
IBM Consulting
IBM Consulting's roots run back to 1991, and it operates today out of Armonk, New York, with a global headcount near 160,000. Rebranded in 2021 from IBM Global Business Services, its AI service offering leans on IBM's own watsonx platform alongside decades of enterprise relationships. For a buyer already standardized on IBM infrastructure, that's a real service advantage; for one that isn't, it narrows the effective scope of what's on offer.
