Berlin-based startup Xayn has rebranded itself after its flagship product, “Noxtua” — a “sovereign European legal AI” aimed at law professionals.  Alongside its new name, Noxtua has secured €80.7mn in funding to refine its AI models and expand to new markets.  The lead investor in the round was C.H.Beck, one of Germany’s oldest publishing houses. Noxtua will use the firm’s database of over 55 million law-related documents to train a new AI model called Beck-Noxtua.  Beck-Noxtua will join Noxtua’s suite of AI models, which work a bit like ChatGPT. However, unlike more general-purpose chatbots, all of the company’s models are trained on “exclusive high-quality legal data sets selected and meticulously labelled by legal experts,” its CEO and co-founder, Dr. Leif-Nissen Lundbæk, told TNW.   The 💜 of EU techThe latest rumblings from the EU tech scene, a story from our wise ol' founder Boris, and some questionable AI art.

Law professionals use the tool to conduct legal research as well as analyse, review, summarise, translate, and draft legal documents. It’s available in several languages, but focuses on German and English.  Noxtua is a AI copilot for lawyers. Credit: Noxtua European ‘sovereign AI’ Noxtua — then Xayn — first launched in 2017. Lundbæk and fellow co-founder Professor Michael Huth spun out the company from research on privacy-first AI solutions at Oxford University and Imperial College London.  Noxtua’s first product was a data privacy-focused mobile search engine. But it later pivoted to fully focus on legal AI, following the launch of its first model last year in collaboration with CMS, Germany’s largest business law firm. Noxtua bills itself as “Europe’s secure and sovereign legal AI.”  “The geopolitical situation has become highly volatile, with historical certainties being questioned,” said Lundbæk. “During these times, independence, sovereignty, and autonomy become ever more important.” Europe’s digital sovereignty will be a hot topic at TNW Conference, which takes place on June 19-20 in Amsterdam.
