QuantumBlack, AI by McKinsey vs Softermii: overview
QuantumBlack, AI by McKinsey
QuantumBlack began in 2009 as a performance-analytics unit for Formula 1 teams, joined McKinsey in December 2015 at roughly 45 people, and now runs McKinsey's AI and generative AI practice out of London across more than 40 offices worldwide, with a reported headcount in the 1,001-5,000 range. Its generative AI work spans large language model deployment, retrieval systems, and agentic workflows, framed with the same discipline the unit brought from motorsport: a claim isn't real until it's tied to a measured number.
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; generative AI consulting is a newer, growing line rather than the founding specialty. Clients get a partner that builds the full surrounding product, not just a generative AI recommendation, at the cost of the depth a dedicated AI-only consultancy can offer.
