The AI Behind the Numbers
Artificial intelligence is transforming the way companies manage their finances—fundamentally and faster than many expect. However, the large, general-purpose AI assistants are only of limited help in accounting. A truly sustainable, legally compliant transformation requires more: a customized approach tailored to your company and a combination of traditional information processing and modern large reasoning models.
With the founding of HWS Intelligence GmbH, we’ve firmly integrated AI into the HWS ecosystem—driven by a team of AI experts, solution architects, and software developers working alongside our tax advisors, auditors, and attorneys.
There are many providers. Trust is the key issue.
Many providers offer AI for accounting today. The crucial question is a different one: Who do you entrust with your financial data—and where is it processed? This is precisely where HWS Intelligence stands out.
AI Readiness
Before AI starts working for you, we carefully prepare your data. This ensures that your accounting remains accurate in real time at all times.
The DNA of Auditing
Over 100 years of proper bookkeeping, audit reliability, and confidentiality—we bring this commitment to AI.
Agentic RAG
The AI independently identifies what information it needs to answer a question. Our system monitors every instance of data access and provides only authorized information.
Data in Germany
Processing in compliance with the GDPR and GoB in ISO 27001-certified data centers in Germany—no routing through third countries.
Tech Meets Tax – All Under One Roof
HWS Intelligence combines over 100 years of expertise in tax, auditing, and consulting with its own proprietary AI development. WKG Software GmbH, based in Hanover—an established software developer with its own cloud data center in Germany—contributes the technological core to the joint venture. Pure-play AI providers understand the technology but lack the foundation in tax law and proper accounting. Traditional firms understand the foundation but do not develop their own AI. HWS Intelligence combines both.
The division of roles is clear: HWS Intelligence GmbH develops and is responsible for the product as an independent joint venture. HWS itself does not act as a provider or distributor of an AI solution—our professionals contribute their tax and audit expertise as initiators and consulting experts.
What's Next
HWS Intelligence is developingJAICOB®, an AI-based financial assistant for German small and medium-sized businesses—named after Jakob Fugger, who introduced double-entry bookkeeping to Germany around 1500.JAICOB® is currently under development and is being carefully prepared for market launch. As soon as it’s ready, you’ll be the first to know right here.
The People Behind It
Technology is only as good as the people responsible for it. These HWS partners bring their professional expertise—particularly in the areas of consulting, process management, tax, and auditing—to HWS Intelligence.
Volker Zehnle combines classic mid-market advisory with a clear focus on digital transformation and AI-supported process optimisation. At HWS, he is also responsible for M&A processes & due diligence as well as business valuations.
As co-initiator of HWS Intelligence, the AI subsidiary of the HWS Group, he drives in particular the practical application of artificial intelligence in finance and accounting.
