C.H.Beck Takes Control of Noxtua After €100M Round

C.H.Beck has taken a majority stake in Berlin legal AI firm Noxtua after a Series C of more than €100 million. The legal publisher is tying its product plan to Noxtua’s platform and clearing out the venture firms and law-firm backers from the last round.

Prof. Dr. Klaus Weber, who sits on C.H.Beck’s executive board, said the family has never spent that much money. The cheque is meant to help Noxtua stand up to Harvey and Anthropic. The control is the other half of the deal.

C.H.Beck Takes the Majority and the VCs Leave

Noxtua closed the round on 23 September 2026. C.H.Beck, which led the company’s 80.7 million euro Series B on 23 April 2025, is now the majority shareholder. Austrian legal publisher MANZ joins as a new investor.

Leaving are Global Brain Corporation, KDDI Open Innovation Fund, CMS, Dentons, and Dominik Schiener, founder of the IOTA Foundation. CMS had been described as a co-initiator of the product. Dentons had come in at Series B to keep the tools close to practice. Both law firms are off the register 17 months later.

WHO OWNS NOXTUA NOW

Weber was careful about what majority means inside a house that still talks like a family firm. In earlier, smaller bets, he said, C.H.Beck did not buy companies off the market or fold them into the publishing house. That habit, he said, has worked, and Noxtua will keep its own identity.

He also said the house will work so closely with Noxtua that the publisher’s product plan is tied to the platform. For that reason it wanted a qualified majority. Freedom is the public line. The share register is the private one.

Dr Leif-Nissen Lundbæk, Noxtua’s founder and chief executive, put the same shift in cash-flow language. Since the Series B, he said, the mix of an agile AI company and a centuries-old family house had worked, so both sides chose to keep that spirit. The firm, he said, is no longer dependent on the short-term venture race.

The Commentary House That Started in 1763

C.H.Beck is a family publishing house founded in 1763 by Carl Gottlob Beck in Nördlingen. It is 263 years old in 2026, and legal commentary is the core of the business. The Munich house runs legal, tax and business publishing on one side and literature, non-fiction and science on the other.

Its own account puts annual output at up to 1,000 new publications and new editions, around 100 specialist journals, and beck-online, which it calls the leading legal database in the German-speaking world. The group, in the Series B notice, employed more than 2,200 people across European sites, with a print works, bookshops and seminar businesses still in the stack.

Noxtua is much younger and has already changed names twice. It was founded in Berlin in 2017 as XAIN AG from research by Lundbæk and Prof. Dr. Michael Huth at Oxford and Imperial College London. The first legal product shipped in February 2024. The company says it now has more than 30,000 users, around 100 staff, and six offices in Berlin, Paris, Stockholm, Zagreb, Munich and Fribourg.

THE PATH FROM NORDLINGEN TO SERIES C

1. 9 September 1763: Carl Gottlob Beck takes over a printing house in Nördlingen, the start of C.H.Beck.
2. 2001: C.H.Beck launches beck-online, now the German-language legal database Weber puts at more than 60 million documents.
3. 2017: XAIN AG is founded in Berlin on privacy-protecting AI research from Oxford and Imperial.
4. February 2024: Noxtua ships as a legal AI product, with CMS as an early legal partner.
5. 23 April 2025: C.H.Beck leads the €80.7 million Series B and the firm rebrands from Xayn AG to Noxtua SE.
6. February 2026: Noxtua launches a single Europe License across publishers and jurisdictions, starting in the DACH region.
7. 23 September 2026: Series C of more than €100 million makes C.H.Beck the majority owner and brings MANZ onto the cap table.

Lundbæk said the team had quadrupled in 12 months and revenue had quintupled in four. He did not publish the bases for those multiples. The headcount figure the company will stand behind is around 100 people.

Why Civil-Law AI Needs Those Commentaries

Continental Europe mostly runs on civil law. Day-to-day work leans on commentary literature that specialist houses have edited for decades, sometimes centuries. Lundbæk’s pitch is that this layer is what makes legal AI usable, and that “almost good” is not good enough for the profession.

Noxtua, he said, does not rest a draft, a review or a research query on a large language model alone. Each request is grounded in curated data from publishing partners. Users see the citations that point back to that material. Weber made the same point in plainer words: a lawyer cannot answer “that is what ChatGPT said.”

With our legal database beck-online, we have the largest legal database in the German-speaking world containing more than 60 million legal documents. We believe that we can make our content a success in the AI market with Noxtua’s technology. Therefore, we decided to link our product strategy very closely with Noxtua, and therefore, it was important for us to have a qualified majority.

Prof. Dr. Klaus Weber, member of the executive board, C.H.Beck

The 60 million figure is beck-online. Separately, Noxtua says that with C.H.Beck, MANZ, Helbing Lichtenhahn and other houses it is building a pan-European legal database of more than 100 million searchable documents, spanning more than 250 years of published law. Those are two different piles. One is the German-language flagship. The other is the network the majority owner now sits on top of.

Money follows the files. Noxtua shares revenue with the publishers that supply the data. Smaller houses in smaller markets, Lundbæk said, keep control of their content and join a wider publisher network rather than handing a corpus to a model lab that may not still be in the market in five years.

Susanne Stein-Pressl, managing partner at MANZ, tied the growth to that posture. She said Noxtua does not have a “move fast and break things” mentality and is interested in sustainable long-term success. For a house that dates its legal expertise at 177 years, that is the due-diligence line.

Harvey Raised $550 Million This Month

On 9 September 2026, San Francisco legal AI company Harvey said it raised $550 million at a $15.5 billion valuation, and that it is used by 80 percent of the 100 highest-grossing law firms in the United States. In March it had raised $200 million at $11 billion. Stockholm-based Legora closed a $550 million round in March 2026 at a $5.55 billion valuation.

Noxtua did not disclose a valuation with the Series C. Next to those marks, more than €100 million is a different sport.

HOW THE LEGAL AI MONEY COMPARES

Lundbæk’s in-house line is “less Hollywood, more substance.” He argues that some rivals raise huge sums and spend them on work that does not make the product better, while Noxtua spends on data, models, infrastructure, security and sovereignty. The company uses high-performance open-source models and is adding closed-source frontier models in a European setup with Deutsche Telekom.

On 25 March 2026 it said it was moving into the Telekom Industrial AI Cloud in Munich, citing the U.S. CLOUD Act and the need to process material in data centres under European control. That hosting claim is also how it sells into courts. A judiciary buyer is a different procurement from an Am Law partnership, and it is one Harvey’s valuation does not automatically win.

Looking three years out, Lundbæk sees three camps: global legal AI platforms such as Harvey and Legora with standardised products; general-purpose model providers such as Claude moving into legal work; and jurisdiction-specific platforms such as Noxtua that sit on curated local data. Providers that do not go deep on a legal system, he said, will be squeezed between the other two. Large firms already buy general-purpose tools direct. That squeeze is the risk his majority owner is paying to avoid.

Workspaces From Munich to Stockholm

The product is not one chatbot. It is a set of jurisdiction-specific Legal AI Workspaces sold with the local house whose files sit underneath. Research, analysis and drafting run in the same place. The first Europe License for Legal AI followed in February 2026, so a lawyer can reach several publishers through one licence, starting in Germany, Austria and Switzerland.

THE EIGHT LEGAL AI WORKSPACES

• Germany: Beck-Noxtua, built on C.H.Beck’s exclusive German-language files and sold as the home-market flagship.
• Austria: MANZ-Noxtua, launched on 24 June 2026 on MANZ content, with MANZ now also a Series C investor.
• Switzerland: Swiss-Noxtua with Helbing Lichtenhahn, including the Basler Kommentar and the Commentaire romand, processed only on Swiss servers.
• Poland, Czechia and Slovakia: Beck-Noxtua local editions with C.H.Beck’s own houses in Warsaw, Prague and Bratislava.
• Bulgaria: Ciela-Noxtua with Ciela Norma AD.
• Sweden: Blendow-Noxtua, announced 27 May 2026 with Blendow Group, plus a Stockholm office.

Those eight markets are not the same thing as the six offices. The offices are Berlin, Paris, Stockholm, Zagreb, Munich and Fribourg. Paris and Zagreb are engineering and expansion sites without a named local publisher workspace on the current access list.

The network is still taking in houses that do not sit on the cap table. On 15 July 2026, Kohlhammer Verlag said selected legal titles would flow into the Beck-Noxtua workspace as part of an expanded content alliance.

Beck-Noxtua is already a named specialist tool in German practice, the kind of system a lawyer prompts when a general chatbot is not the file they want in the correspondence. That is the distribution C.H.Beck just bought a majority of: the commentary brand lawyers already trust, wired into the drafting loop.

A Human Still Has to Take Responsibility

Lundbæk draws a hard line at the signature. AI, he said, can prepare drafts and run multi-step analyses that used to take hours. Taking on responsibility is still something AI is not, and probably will not be, able to do, because legal systems are built so that a human has to own the decision.

Noxtua was founded almost ten years ago out of my PhD thesis at Oxford University that focused on privacy-protecting AI. A lot has changed since then, but what hasn’t changed is our deep conviction that we need powerful AI based on European values. With Noxtua, we’re trying to see Legal AI not only as a tool that saves legal professionals time, but also as a responsibility to the rule of law.

Dr Leif-Nissen Lundbæk, founder and CEO, Noxtua

The company says it meets Section 203 of the German Criminal Code and Section 43e of the Federal Code for Lawyers, and that it holds BSI C5, ISO 27001 and ISO 42001. Weber added a public-administration pitch: if courts stay slow, trust in the state thins, and legal AI that helps the judiciary work faster can close some of that gap.

The Series C does not settle whether a family commentary house can outrun a $15.5 billion San Francisco platform. It does settle who owns the European attempt. The files, the majority, and the product plan now sit in the same place, and the venture names from 2025 do not.

Frequently Asked Questions

Who founded Noxtua, and what did they study?

Noxtua lists three founders: Dr Leif-Nissen Lundbæk, Prof. Dr. Michael Huth and Felix Hahmann. Lundbæk’s company biography gives him a degree in economics from Humboldt University in Berlin, an MSc in mathematics from Heidelberg, an MSc with distinction in software engineering from Oxford, and a PhD in computer science from Imperial College London, plus earlier work at Daimler and IBM. Huth is the Imperial College professor on the original research; the pair spun the company out of privacy-protecting AI work rather than out of a law firm.

When did beck-online launch, and how big is C.H.Beck’s catalogue?

C.H.Beck launched beck-online in 2001, after publishing its first legal database on CD-ROM in 1989. The publisher’s own description puts current output at up to 1,000 new publications and new editions a year and around 100 specialist journals, with Nomos inside the group since 1999. Weber’s Series C figure of more than 60 million documents is the live size of that database, not the 2001 starting set.

Which security and AI certificates does Noxtua hold?

Beside ISO 27001 and BSI C5, Noxtua’s milestone list says it was the first German company certified to ISO/IEC 42001, the international standard for AI management systems. The same list names ISO 9001, ISO/IEC 27017 and ISO/IEC 27018. A Telekom partnership note also cites SOC 2. Those marks are how it argues that a lawyer can put a client file into the workspace without a separate anonymisation pass.

What do Section 203 and Section 43e actually require?

Section 203 of the German Criminal Code makes it an offence for lawyers and other professional-secrecy holders to reveal protected facts they learn in practice. Section 43e of the Federal Code for Lawyers sets when a lawyer may use an outside service, including cloud software, without breaking that duty. Noxtua’s Series B notice said client prompts and uploads are processed in working memory, are not stored long-term, are not used to train models, and are not readable in plain text by the company, which is the operational answer it gives to those two sections.
