QuantumBlack, AI by McKinsey vs Exadel: 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.

The firm lists AI and data management as one of five core service areas alongside strategy consulting, digital experience, digital products, and managed services, reflecting a broad technology consultancy rather than an AI-only specialist.
