Gartner vs Slalom: 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.
Slalom
Slalom has more than 10,000 employees in over 50 offices and was founded in Seattle in 2001. Its AI and data strategists work on governance and operating models, and a new chief AI officer arrived in August 2026. Close ties with the major cloud and data vendors mean its advice usually points toward those platforms.
