West Monroe vs Thoughtworks: 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.
Thoughtworks
Thoughtworks was founded in Chicago in 1993 and has roughly 10,000 staff. Apax Partners took it private in a deal announced in August 2024 that valued the company at about $1.75 billion. Its AI work grows out of software and data engineering, so strategy engagements focus on where AI changes how software is built and how data products are run. In March 2026 it launched an AI joint venture with Teneo, a New York advisory firm, to add a stronger business-advisory side. Its public Technology Radar, a twice-yearly review of tools and techniques, is a free way to judge how it thinks before you hire it.
