BABL AI vs Advai: overview
BABL AI
BABL AI was founded in 2018 in Iowa City by astrophysicist turned auditor Shea Brown, a founding member of the International Association of Algorithmic Auditors. It runs independent, criteria-based audits and certifications, starting with automated hiring tools and now covering EU AI Act risk management. It also trains auditors through its own courses. The firm is small, and its strength is a clean separation between whoever built the system and whoever checks it.
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.
