TÜV SÜD vs ML6: overview
TÜV SÜD
TÜV SÜD traces its history to 1866 and is headquartered in Munich, with around 28,000 employees worldwide. It tests and certifies products, and its AI services assess whether a defined AI system meets EU AI Act requirements and related standards. The TÜV AI.Lab built an AI Risk Navigator that sorts systems into the Act's risk classes, and TÜV SÜD has launched a test mark for low-risk AI. It assesses instead of designing strategy, which makes it a useful independent check on someone else's work.
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.
