West Monroe vs Slalom: 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%.

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.
Slalom

In August 2026 it hired a former Accenture executive as its chief AI officer.
