Deloitte vs Slalom: 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.
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.
