QuantumBlack, AI by McKinsey vs Neurons Lab: 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.
Neurons Lab
Neurons Lab was founded in London in 2019 and has roughly 50 to 100 staff, topped up by a wider network of contract engineers. It is an AWS Advanced Partner with the Machine Learning Competency and works mainly for banks, insurers, and wealth managers. Strategy here means AI discovery and roadmap work that hands straight into prototypes on AWS. Clutch lists a $100,000+ minimum project, high for a firm this size and a sign that it aims at established financial companies.
