PA Consulting vs Advai: overview

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.

Advai

Advai was founded in London in 2020 and has somewhere between 20 and 30 staff. It tests AI systems for robustness, benchmarks them, and monitors them, and its guardrail framework for large language models is listed in the UK government's AI assurance techniques catalogue. In December 2025 the Financial Conduct Authority (FCA) named it the technical partner for its AI Live Testing pilot with financial firms. Its work is technical testing more than strategy.
