DeepJudge brings scalable AI to CMS Switzerland for legal search

DeepJudge, a Microsoft partner, helps CMS Switzerland streamline law firm operations and securely scale institutional knowledge using Microsoft Azure AI.

February 26, 2026

Legal work depends on precision, precedent, and the ability to apply institutional knowledge across diverse matters. For many firms, that knowledge is documented but not always easy to access or act on. DeepJudge, a Microsoft partner, is helping legal teams bridge that gap with AI-powered search and workflow tools built on Microsoft Azure.

DeepJudge specializes in enterprise search and agentic AI workflows tailored for legal professionals. DeepJudge participated in Microsoft for Startups and the Pegasus Program, a selective initiative that helps high-potential partners scale through technical guidance, go-to-market support, and early access to Microsoft innovations. Today, the company’s platform is built on Microsoft Azure—including Azure OpenAI Services, Azure Kubernetes Service, and Microsoft Defender for Cloud—to promote high performance and robust data protection.

Making internal knowledge accessible—and secure

CMS Switzerland, a full-service law firm with more than 160 employees and a legacy spanning over 80 years, offers tailored legal solutions for businesses, investors, and private individuals. Known for its deep legal expertise and cross-border capabilities, CMS Switzerland built a strong foundation of internal knowledge—contracts, case files, templates, presentations, and precedent documents—stored across various systems and folders. While this information was historically well maintained, it wasn’t always easy for lawyers to locate and apply it consistently across cases.

“Clients hire law firms for their expertise—but law firms often underestimate their breadth and depth of existing knowledge and experience,” said Stefan Brunnschweiler, Managing Partner at CMS Switzerland. The firm wanted to better surface and apply its internal expertise across teams—without disrupting existing workflows or compromising on data protection. The goal was to institutionalize internal know-how so that all employees could access and apply it confidently in their daily work.

Security was a critical consideration. As part of CMS, one of the largest international law firms with over 7,200 lawyers in 92 offices across 50 countries, CMS Switzerland needed a solution that could meet strict data protection requirements while offering the flexibility and performance of modern AI tools.

“Data security is our top priority,” Brunnschweiler emphasized. “The fact that Microsoft hosts our data in Switzerland and that DeepJudge, through Microsoft, also ensures high data protection convinced us.”

CMS Switzerland began exploring options that could help surface internal knowledge more efficiently, reduce time spent on manual research, and support faster onboarding of new employees. The firm was looking for a solution that could meet the highest standards for security, reliability, and usability—while also aligning with the operational realities of legal work.

AI-powered search and workflows built for legal teams

DeepJudge’s platform, built on Microsoft Azure, offered the right combination of legal-specific AI capabilities and trusted infrastructure for CMS Switzerland. Key capabilities include:

  • DeepJudge knowledge search: The high-performance enterprise search engine is designed to scan millions or billions of documents quickly and precisely, helping lawyers locate relevant templates, language, and other precedents in seconds without needing to navigate multiple systems or folders.

  • DeepJudge AI workflows: Powered by the enterprise search engine and utilizing retrieval-augmented generation (RAG)—a method that combines generative AI with verified internal sources to deliver reliable, traceable content—DeepJudge’s AI workflows integrate directly into CMS Switzerland’s existing processes, allowing teams to compare documents, translate lengthy texts, and draft legal materials more efficiently.

“DeepJudge AI allows us to turn our collective experience into a usable asset—streamlining workflows and making it significantly easier to find relevant precedents and insights,” said Brunnschweiler.

With services including Azure OpenAI Services, Azure Kubernetes Service, Azure Blob Storage, and Microsoft Defender for Cloud, the solution provided modern AI performance and flexibility—while ensuring data residency in Switzerland, a requirement for strict legal compliance and essential for client trust.

Today, DeepJudge continues to provide ongoing support and training, helping CMS Switzerland evolve its use of AI over time. “Enterprise search is one of the most critical components of any tech stack—especially in law firms,” said Paulina Grnarova, CEO and co-founder of DeepJudge. “Search is no longer an add-on—it’s the backbone of generative AI in legal.”

The introduction of AI also prompted a shift in how CMS Switzerland’s internal teams work. They implemented targeted training and regular feedback sessions to support adoption, and DeepJudge continues to work closely with the firm to incorporate suggestions and provide ongoing training.

“Clients will soon expect the use of AI as a matter of course,” said Dirk Spacek, Partner and Head of IT/IP at CMS Switzerland. “The efficient use of internal data in combination with AI will become the key success factor for modern law firms.”

DeepJudge plans to continue its collaboration with Microsoft to stay ahead of evolving AI capabilities. “We’re proud to be part of the Microsoft ecosystem,” said Grnarova. “It keeps us at the technological forefront and gives us early access to Microsoft tools, which benefits our clients.”
