Deloitte vs ML6: overview
Deloitte
With more than 460,000 people and roots in an 1845 London accounting practice, Deloitte has the widest reach of any firm on this list. Its AI advisory sits next to risk and regulatory teams, which helps banks, insurers, and health systems that must document how each model is governed. Deliverables tend to be thorough and heavy. Expect large teams, long timelines, and a natural path into Deloitte's own implementation 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.
