QuantumBlack, AI by McKinsey vs Softermii: 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.

Softermii

Softermii has run out of Los Angeles since 2014, with reported staff between roughly 88 and 120. Its core identity is custom software and platform development; AI consulting is a newer, growing line rather than the founding specialty. Clients get a partner that builds the full surrounding product, not just an AI recommendation, at the cost of the depth a dedicated AI-only consultancy can offer.
