Berlin-based AI startup Noxtua has raised $92.2 million (€81.2 million) in a Series B funding round to build a sovereign AI system tuned specifically to the German legal framework. The round marks a significant step toward creating jurisdiction-specific legal AI for enterprise and government use across Europe.
Previously known as Xayn, the company initially launched as a privacy-first, on-device AI search engine. Now, under the Noxtua brand, it’s building “Beck-Noxtua,” a next-gen legal AI system in partnership with C.H. Beck, Germany’s most prominent legal publisher.
A Strategic Alliance with Germany’s Legal Backbone
C.H. Beck led the Series B round and is more than just a financial backer. The publisher holds the most extensive archive of German legal rulings and case law — 55 million documents in total, which will serve as the exclusive training dataset for Beck-Noxtua. This makes it the largest legal data source in the German-speaking world.
“Noxtua’s vision of a sovereign European legal AI aligns hand in hand with our values,” said Professor Dr. Klaus Weber, Executive Board Member at C.H. Beck. “It’s a cornerstone of our innovation strategy.”
Built for Germany, Hosted in Germany
The funding round also includes strategic participation from:
- Northern Data Group (high-performance computing & cloud infrastructure)
- CMS (Germany’s largest business law firm)
- Dentons (global law firm)
By leveraging Northern Data’s Frankfurt-based infrastructure, Noxtua ensures that all AI processing remains within German borders, a key requirement for compliance amid increasing geopolitical and regulatory scrutiny.
“U.S. foundational models are trained on American and UK legal data, which simply don’t translate to German legal standards,” said Dr. Leif-Nissen Lundbæk, CEO and Co-Founder of Noxtua. “That’s why we had to build our own — from the ground up — using localized legal knowledge.”
German Legal AI: A Sovereign Approach
Noxtua’s AI model, based on a custom transformer architecture, is designed to:
- Research German legal issues
- Draft and analyze contracts
- Assist law firms and corporate legal teams in staying compliant
While most commercial AI systems struggle with non-English, jurisdiction-specific nuances, Noxtua’s specialization in German law gives it a distinct edge. And in a region where legal compliance is both complex and critical, precision isn’t optional — it’s mandatory.
Backed by Research, Built for Real-World Legal Use
Noxtua’s tech roots trace back to research at Oxford University and Imperial College London, later refined in collaboration with CMS’s legal teams.
“We’ve already rolled it out to a number of law firms and corporate legal departments,” said Lundbæk.
As legal institutions across Europe look for AI tools that meet strict compliance requirements, Noxtua aims to become Europe’s answer to U.S.-centric platforms like Thomson Reuters’ CoCounsel or Lexis+ AI — but tailored for civil law systems and hosted locally.
As the demand for sovereign AI grows, Noxtua stands at the forefront of legal tech innovation in Europe. With deep domain expertise, proprietary data, and a powerful cloud partnership, the startup could reshape how legal work is done in Germany — and potentially beyond.
