Deloitte vs ML6: overview

Deloitte

Deloitte traces its roots to London in 1845 and today employs more than 460,000 people across its member firms. Its AI strategy work runs through the consulting arm, often next to risk and regulatory teams, which is why it turns up most often in banking, insurance, health, and government programs. A company that has to show regulators how every AI system is governed will find that combination hard to match. Pace and price are the trade-off. Engagements are big, staffed with large teams, and priced accordingly.

ML6

Ghent-based ML6 has worked on AI since 2013 and employs 140+ specialists across Belgium, Germany, and the Netherlands. OpenAI named it one of its services partners in June 2025. It sells strategy and engineering together: discovery workshops and roadmaps first, then model building and deployment by the same people. Because its clients are European, EU AI Act and General Data Protection Regulation (GDPR) questions come up as ordinary project work.
