About us
Noxtua is Europe's leading sovereign Legal AI. The legally compliant and competent AI helps legal professionals to research legal issues and review, and draft legal documents. The GDPR-compliant Legal AI meets the high professional and data protection requirements for lawyers (§ 203 Penal Code, § 43e Federal Lawyers' Act) and is certified according to ISO 27001, 9001, 27018, 27017, 42001, and BSI C5. The product version Beck-Noxtua is based on the exclusive data of Germany’s leading legal publisher C.H.Beck and Germany’s largest business law firm CMS.
Emerging from a 2017 research project by Dr. Leif-Nissen Lundbæk and Professor Dr. Michael Huth at Oxford University and Imperial College London, the Berlin-based Legal-Tech company, formerly known as Xayn, boasts extensive experience in developing highly efficient GDPR-compliant AI solutions. Strategic partners, including Germany's leading legal publisher C.H.Beck, the High-Performance Computing specialist Northern Data, Germany's largest business law firm and co-initiator of the Legal AI Noxtua CMS, as well as the world's largest law firm Dentons, have invested a total of € 80.7 million in the German startup as part of its Series B funding round.
We explicitly encourage women to apply, as they are currently underrepresented. Our goal is to build a diverse and inclusive work environment that values different perspectives. Of course, we welcome applications from all qualified individuals – regardless of gender, ethnic origin, religion, disability, age, or sexual identity.
