Gartner vs West Monroe: overview

Gartner

Gartner was founded in 1979, is based in Stamford, Connecticut, and has around 21,000 employees. It sells research subscriptions and analyst access, and it doesn't implement anything, so its advice on AI vendors, build-or-buy choices, and governance carries no delivery sale. There is a catch. Technology vendors are also Gartner clients, and the advice is general research applied to your case more than a bespoke plan. CDOs and CIOs use it most for vendor selection and benchmarking.

West Monroe

West Monroe has operated from Chicago since 2002, has about 2,250 people, and is partly employee-owned. 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.
