C.H.BECK takes majority control of the AI developer built on its legal commentary

A German lawyer cites the annotated commentary published alongside legislation and court decisions, and across much of continental Europe practice depends on that commentary ^[6]. Noxtua's jurisdiction-specific workspaces for research, analysis and drafting are built around licensed material from C.H.BECK, MANZ and Switzerland's Helbing Lichtenhahn ^[5]. A vendor gets a corpus like that by licensing it.

Lundbæk and his PhD supervisor Michael Huth founded the company in Berlin in 2017, drawing on work at Oxford University and Imperial College London; it traded as Xain, then Xayn, and shipped the first Noxtua legal product in February 2024 ^[17].

Until this round the German corpus reached the product through a licence between two companies. C.H.BECK now holds the majority of the licensee. Klaus Weber of C.H.BECK told Tech.eu that the publisher plans to tie its product strategy closely to Noxtua's platform while allowing Noxtua to retain its identity and flexibility ^[8]. For the other publishers in the stack the direction is the opposite: MANZ, which had already built an Austrian workspace with Noxtua before joining this round ^[18], and Helbing Lichtenhahn are licensing content into a platform majority-owned by a competing publisher. Lundbæk told Tech.eu that Noxtua shares revenue with publisher partners and lets them retain control over their content ^[11].

C.H.BECK also led the 80.7 million euro Series B in April 2025, which brought in Northern Data, CMS and Dentons and coincided with the change from Xayn AG to Noxtua SE ^[9]. The Series C is at least 19.3 million euros larger, roughly 24 percent ^[1]. Part of it goes to the five departing holders, so the sum available to the business is smaller than the headline ^[4]. The report leaves the primary-secondary split undisclosed, along with C.H.BECK's percentage and any valuation for Noxtua ^[4].

The round is intended to fund product work, hiring and European expansion ^[14]. Revenue quintupling over four months and headcount quadrupling over a year are presented in the report as company-reported rates without underlying revenue figures ^[12], and the more than 30,000 legal professionals Noxtua reports using the product are not split into paying and other users ^[13].

Expansion here is corpus assembly, one jurisdiction at a time. Noxtua's March 2026 announcement of a Swiss specialist team named publishing partnerships in Germany, Austria, Switzerland, Poland, the Czech Republic and Slovakia, and the company's office listing puts the Swiss office in Fribourg ^[15]. Lundbæk told Tech.eu that workspaces launched with local publishers in Poland, Sweden and the Czech Republic during the four weeks before the September 23rd report ^[16]. Sweden was not among the countries in the March list ^[2].
