How HSP GRUPPE builds AI capabilities for tax advisory
HSP GRUPPE integrated ChatGPT Enterprise into its tax advisory and legal operations to transform its organizational operating model. The firm focused on scaling AI capabilities through shared Agents and governance rather than using it as a simple productivity tool.
Why it matters
Automating repetitive preparation tasks allows professionals to spend more time on client advisory, such as reducing real estate investment evaluations from nine hours to two. This increases the firm's capacity for additional client work and shortens turnaround times.
The details
- 98.6% of surveyed employees reported higher productivity using ChatGPT Enterprise.
- The organization estimates 40,000 hours of additional annual capacity across its network.
- Users exchanged over 500,000 messages between February 1 and July 14, 2026.
