HSP GRUPPE: AI as Operating Model

In a move that redefines how professional services firms operate, HSP GRUPPE has embedded ChatGPT Enterprise deep within its tax advisory and legal research functions. This isn't about faster emails. It's about fundamentally rethinking the professional workflow itself, as detailed in a recent announcement.

For years, HSP GRUPPE has been a proponent of digital standardization. When generative AI emerged, they saw an opportunity beyond mere productivity gains. The leadership posed a critical question: what happens when AI becomes an integral part of a professional services firm's operating model? This vision has led to the integration of AI across tax advisory, legal research, client communication, and financial analysis.

Organizational Transformation, Not Just Software

HSP GRUPPE approached the AI rollout as a comprehensive organizational transformation. Central to their strategy were adoption, governance, and ongoing education. Monthly AI forums provide a platform for employees to share practical applications and learn from each other. While ChatGPT Enterprise's security features are foundational, client data handling adheres strictly to HSP's internal data protection and confidentiality protocols. Importantly, final professional review and responsibility always rest with the human expert.

The goal is to build a scalable organizational capability. Standardized use cases are being developed into custom Agents. For example, the 'AI Client Communication' Agent helps draft client communications, focusing on structure, clarity, and tone. Another, the 'Booking Assistant SKR03 & SKR04,' aids in classifying booking queries. These shared Agents democratize best practices, making them accessible to all employees, not just AI power users.

Augmenting Expertise, Not Replacing It

Professionals at HSP GRUPPE are reporting significant time savings and enhanced work quality. Partner Magdalene Posnak reduced the time for evaluating multiple real estate investments from nine hours to around two, freeing up substantial time for client advisory work. Managing Partner Frank Heibel uses ChatGPT as a sparring partner for complex tax questions, elevating his work. Lawyer and tax advisor Jan-Henrik Leifelt emphasizes that AI strengthens his professional judgment rather than replacing it.

The firm is already looking ahead to the next wave with ChatGPT Work. This involves piloting agentic AI to automate complex workflows safely, balancing governance, quality, and cost. The economic benefit isn't about reducing headcount, as HSP firms are already at capacity. Instead, saved time is being redirected to additional client work, faster turnaround times, and enhanced client service.

Redesigning Workflows for the Future

CEO Carsten Schulz highlights the potential for redesigning entire processes. Consider year-end accounting: instead of discovering missing information months after bookkeeping closes, HSP is exploring how ChatGPT Work could continuously review bookkeeping, identify gaps year-round, and proactively request documents. This shift from AI assisting tasks to AI orchestrating entire workflows signifies the next stage of HSP's AI journey.

The firm estimates this initiative could create approximately 40,000 additional annual hours of capacity. Roughly 28,000 hours could support billable specialist work, with the remainder dedicated to administration and client service. This translates to a theoretical annual revenue potential of approximately €3.8 million, based on conservative hourly rates.

Leadership Lessons from the Front Lines

HSP GRUPPE's experience offers several key leadership lessons. They advocate treating AI as an organizational capability, not just an individual tool. Scaling successful experiments into repeatable workflows, investing in strong operational foundations, and fostering a culture of continuous learning are paramount. Crucially, they advise redesigning workflows, not just automating isolated tasks, and building AI to enhance, not replace, professional judgment.

The broader implications for the professional services sector are significant. Firms that successfully integrate AI into their operating models, focusing on augmenting human expertise and redesigning processes, stand to gain substantial competitive advantages. This approach contrasts with companies focused solely on task automation. It highlights a maturation in how enterprises are thinking about AI deployment, moving beyond simple tools to strategic integration.

For founders in the AI space, HSP GRUPPE's strategy demonstrates a clear enterprise demand for solutions that integrate deeply into existing workflows and can be governed effectively. Investors would do well to look for AI companies that can articulate not just their technology, but their vision for organizational transformation alongside it.
