HSP GRUPPE reports firm-wide ChatGPT Enterprise adoption
OpenAI published an August 7 case study on HSP GRUPPE using ChatGPT Enterprise across tax advisory, auditing, and law-firm work.
The reported numbers are notable: 98.6% of employees reporting higher productivity, 84% weekly active usage, more than 500,000 ChatGPT conversations over six months, and an estimated 40,000+ annual hours of additional capacity across the firm network.
The interesting part is less "AI writes tax advice" and more operating model change: shared workspace, common practices, and firm-wide adoption instead of scattered individual use.
