PA Consulting vs West Monroe: overview
PA Consulting

Jacobs has owned 65% since 2021, with staff holding the rest. Its AI advice tends to come from teams that also design and build products, especially for government, defense, and health clients in the UK and Nordics. That makes the advice practical, though rarely independent of a build.
West Monroe

A chief AI officer joined in September 2025, and in June 2026 it launched WestMonroe.ai, a set of on-demand AI agents. Its advisory starts from operations and cost, which COOs tend to like. European regulation is a thinner part of its practice.
