Trilateral Research vs Gartner: overview
Trilateral Research
Trilateral Research was established in 2004 and is headquartered in London, with an Irish operations center in Waterford. It began in research and data protection and now advises on responsible AI, including fundamental rights impact assessments of the kind the EU AI Act requires for some high-risk deployments. Directory estimates of its size range from about 55 to 200 people. It also builds its own ethical AI software, mostly for public-sector and law-enforcement users.
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.
