QuantumBlack, AI by McKinsey vs Ekimetrics: overview

QuantumBlack, AI by McKinsey

QuantumBlack started in London in 2009 as an independent analytics firm and has been part of McKinsey & Company since 2015. McKinsey says it now has more than 1,000 technical practitioners, plus an R&D group, QuantumBlack Labs, of around 200 engineers, designers, and data scientists (per company website; independently unverifiable). A typical engagement pairs a strategy team that works with the chief executive and board with data scientists who build the first models, so the roadmap and the proof come from one firm. That access to the top of a company is the main reason to hire it. Price is the other side of it: fees follow McKinsey's own levels and are not published.

Ekimetrics

Ekimetrics was founded in Paris in 2006 and has 400+ data scientists and consultants across Paris, London, New York, Hong Kong, and other offices. Best known for marketing-mix measurement, it has added AI strategy and sustainability analytics, and in February 2026 it bought Actable, a customer analytics software company. Strategy engagements start from outcomes you can measure, such as marketing return or emissions. The scope is narrower than a general AI roadmap but much easier to tie to a budget line.
