Noxtua raises more than €100M and gives legal publisher C.H.BECK a majority stake

Why it matters

Noxtua's Series C puts a legal publisher in control of a legal AI developer. It tests whether privileged content access can outweigh rivals' larger funding rounds.

Leif-Nissen Lundbæk has closed a Series C of more than €100 million for Noxtua, with German legal publisher C.H.BECK becoming the Berlin-founded legal AI developer's majority shareholder. Austrian publisher MANZ is joining as an investor, while five existing backers are exiting, according to Tech.eu's September 23rd report. The ownership change puts the supplier of a core ingredient - authoritative legal content - in control of the business building the software around it.

Lundbæk's route to that deal began with privacy research, rather than a legal publishing venture. He and his PhD supervisor, Michael Huth, founded the business in Berlin in 2017, drawing on work at Oxford University and Imperial College London. Lundbæk had previously worked at Daimler and IBM. The business first operated as Xain and later Xayn; it released the first Noxtua legal AI product in February 2024. In a company interview, Lundbæk described legal work as a test of his original aim: building AI that can handle sensitive information without surrendering control of it.

That aim has become a commercial strategy. Noxtua sells jurisdiction-specific workspaces for legal research, analysis and drafting, built around licensed material from publishers including C.H.BECK, MANZ and Switzerland's Helbing Lichtenhahn. In much of continental Europe, lawyers depend on publisher-produced commentary alongside legislation and court decisions. Access to those collections gives Noxtua material to ground answers in; it also gives their owners substantial influence over how the product develops.

The content owner takes control

C.H.BECK led Noxtua's €80.7 million Series B in April 2025. That financing brought in computing provider Northern Data and law firms CMS and Dentons; it also coincided with the change from Xayn AG to Noxtua SE. C.H.BECK and Noxtua went on to launch a joint German legal AI workspace. The new majority stake deepens a relationship that was already about product development and distribution, not simply investment returns.

C.H.BECK executive Klaus Weber 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. He said C.H.BECK's beck-online database holds more than 60 million documents and identified that content as a reason to seek a qualified majority. For C.H.BECK, control of Noxtua offers a way to carry its legal library into AI-assisted work. For Lundbæk, it brings a committed content owner and investor into the same partnership.

MANZ had already worked with Noxtua on an Austrian legal AI workspace before joining this round. The reported exits are Global Brain Corporation, KDDI Open Innovation Fund, CMS, Dentons and IOTA Foundation co-founder Dominik Schiener. Those changes make the financing more consequential than its headline amount. Because the deal includes exits, the more-than-€100 million round figure should not be treated as the amount of fresh operating cash Noxtua received. Nor does a majority stake establish C.H.BECK's exact ownership percentage or the value assigned to Noxtua in the transaction.

Lundbæk told Tech.eu that Noxtua shares revenue with publisher partners and lets them retain control over their content. He said revenue had quintupled over the preceding four months and the team had quadrupled over the preceding year. Those are company-reported growth rates without underlying revenue figures. Noxtua also says more than 30,000 legal professionals use its product; that user count does not distinguish paying customers from other users. The round is intended to fund product work, hiring and European expansion, according to the report.

A local-content bet against larger rivals

Noxtua's expansion requires assembling legal material market by market. Its March 2026 announcement of a Swiss specialist team's arrival named publishing partnerships in Germany, Austria, Switzerland, Poland, the Czech Republic and Slovakia. Noxtua's own office listing places its Swiss office in Fribourg. Lundbæk told Tech.eu that Noxtua had launched workspaces with local publishers in Poland, Sweden and the Czech Republic during the four weeks preceding the September 23rd report.

The capital available to competitors is considerable. US-based Harvey said it raised $200 million in March 2026, while Legora announced a $550 million round that month. Italy's Lexroom announced a $50 million Series B in May for expansion into other European civil-law markets. The figures are company announcements, and none establishes which product produces more dependable legal work. They do show why Lundbæk is building a publisher network that a well-funded rival cannot obtain merely by spending more on models.

Noxtua's model choices also show how it is balancing its European-sovereignty pitch against customer demand. Its product documentation describes a self-hosted option using open-weight models on European-controlled infrastructure and a separate option for closed-source frontier models accessed through Deutsche Telekom. Noxtua says the latter uses a dedicated Google processing environment in an EU data center with zero retention during inference; availability depends on the market and workspace settings. That distinction matters to buyers handling confidential work: a European data center and a fully European-controlled processing chain are different propositions.

Lundbæk is betting that local legal sources, publisher distribution and choices about where sensitive work is processed will carry more weight than a single model's capabilities. C.H.BECK's majority stake commits a powerful supplier to that bet. It also means Noxtua's next stage will be shaped by the publisher whose content helped make the product possible.
