QuantumBlack, AI by McKinsey vs IBM Consulting: 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.
IBM Consulting
IBM Consulting traces to 1991 and is headquartered in Armonk, New York, with roughly 160,000 employees globally. It was rebranded in 2021 from IBM Global Business Services, and its AI consulting work draws on IBM's own watsonx platform and decades of enterprise technology relationships. That platform tie-in is a genuine differentiator for clients already invested in IBM infrastructure, and a real constraint for clients who aren't.
