West Monroe vs ML6: overview
West Monroe
West Monroe was founded in Chicago in 2002 and has about 2,250 people in nine US offices, plus London and San José, Costa Rica. Part of the firm is owned by its employees; a 2023 interview put that share at 50%. It hired a chief AI officer in September 2025 and in June 2026 launched WestMonroe.ai, a platform of on-demand AI agents. Its AI strategy work begins with operations. When a utility, bank, or health system wants to know where AI changes how the business actually runs, before anyone picks a model, this is the kind of firm that answers well.
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.
