BABL AI vs ML6: 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.
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.
