BABL AI vs Zühlke: overview
BABL AI

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.
