Deloitte vs West Monroe: 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.
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.
