ML6 vs Advai: overview
ML6
ML6 has been building AI in Ghent since 2013 and employs 140+ people in Belgium, Germany, and the Netherlands. Its strategy work covers ambition-setting workshops, use-case discovery, and EU AI Act questions, and OpenAI named it a services partner in June 2025. Most clients go on to build with ML6, so the advice is grounded in engineering reality but not neutral about who builds.
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.
