Steuerrecht.com is a boutique law and tax advisory firm that aims to compete at the same level as much larger practices. Founder Sebastian Korts and his ten-person team handle complex tax cases, financial analyses, and litigation, often against institutions with far greater resources.
The challenge was finding the bandwidth to serve more clients, while keeping standards high. “Without in-house departments, a small firm can only stretch so far,” Korts explains. By adopting ChatGPT Business, Korts found a way to multiply his firm’s reach and visibility with their existing team, turning time once lost to routine work into client acquisition and growth.
## Creating virtual departments with AI
What large firms achieve through specialized staff, Steuerrecht.com now does with AI. “By committing strongly to artificial intelligence, we can now create things we were never able to before,” Korts says.
With ChatGPT Business, the firm has effectively built its own set of “virtual departments”:
## Legal work in hours instead of days
These virtual departments have reshaped the firm’s core legal workflows. What used to consume days of manual effort is now completed in hours, or even minutes:
“In immediate application, it delivers incredibly impressive results for a firm like ours,” Korts says. “Compared to traditional methods, I personally save up to ten hours of work per week thanks to ChatGPT.” That extra capacity goes into building the firm’s visibility and reaching new clients, work that was difficult to prioritize before.
## Speaking every language clients need
One of Steuerrecht.com’s most distinctive uses of ChatGPT Business is what Korts calls “translation”—not only across languages, but also across audiences. Clients may need a message translated from German to English, and complex subject matter has to be made digestible for different audiences, from judges, to local business clients, to international executives.
“I may need to explain to a foreign CFO that the German tax authority now treats certain transfer-pricing misstatements as criminal,” Korts says. “That kind of communication has to be crystal clear, in their own frame of reference.”
ChatGPT makes this reframing not only possible, but fast. “If I defend a corporate officer accused of tax fraud, the court submission may run to 35 pages,” Korts explains. “That has to be translated into one and a half pages for the board—and sometimes again into English so foreign CFOs grasp the seriousness. For that kind of work, ChatGPT is the only real partner.” As a result, clients feel better informed and more confident in the decisions they make with Steuerrecht.com.
## Secure by design, adopted as a team
Confidentiality is non-negotiable in law. Steuerrecht.com chose ChatGPT Business specifically to support GDPR compliance and because the product does not train on customer data. “We are legally bound to confidentiality,” Korts says. “This isn’t optional, it’s in the law. Security was the deciding factor.”
Adoption, meanwhile, was deliberate and firm-wide. The team held morning sessions to refine prompting, compare approaches, and align on best practices. Today, they maintain weekly syncs to ensure consistent competence.
“The speed and impact are so significant that it would be unreasonable not to use it,” Korts says. “But we also need a unified approach, so we never show up to clients with uneven skills.”
## Turning a boutique firm into a bigger player
For Steuerrecht.com, AI has become a way to level the playing field. With ChatGPT Business, the firm can take on the same complex tax cases as much larger practices, without sacrificing security or quality.
Korts is candid with clients about how central AI has become. “Yes, we use AI—and we say it proudly,” he notes. “ChatGPT is a real productivity driver.”
Looking ahead, the team is exploring new applications, from automated legal update newsletters to precedent search and multilingual workflows. But for Korts, the real impact is already clear: “ChatGPT Business is a high-quality tool that will definitely move us forward.”
