Trilateral Research vs PA Consulting: 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.

PA Consulting

PA Consulting started in 1943 as Personnel Administration and is now a London-based firm with about 3,900 employees and £753 million in 2024 revenue. 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.
