Slalom vs Thoughtworks: overview
Slalom
Slalom was founded in Seattle in 2001 and has more than 10,000 employees in over 50 offices across the Americas, Europe, and Asia. In August 2026 it hired a former Accenture executive as its chief AI officer. Its AI strategy practice covers operating models, governance, and data strategy, delivered by local teams who work on-site with clients. Partnerships with Microsoft, AWS, Google Cloud, Snowflake, and Salesforce mean a Slalom roadmap usually lands on one of those platforms.
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.
