Agentic AI in Professional Services: Why Law, Tax, and Consulting Lead Adoption
Professional services firms are adopting agentic AI faster than nearly every other sector. AI adoption in accounting firms jumped from 9% to 41% in a single year. 92% of legal professionals now use at least one AI tool daily. The reasons are structural: billable-hour economics make ROI obvious, document-heavy workflows are a natural fit, and clients are demanding it. Platforms like Intapp Celeste, Harvey, and Thomson Reuters CoCounsel are purpose-built for these regulated industries.
