As artificial intelligence rapidly enters the legal sector, one challenge continues to concern lawyers and legal professionals worldwide: reliability. While large language models have demonstrated impressive capabilities in drafting and research, legal work requires precision, traceability, and verified sources where even small inaccuracies can create major professional and regulatory risks. Milan based legal AI company Lexroom is aiming to solve that problem through a data driven approach built specifically for legal systems, and investors are backing the company with major new funding.
Lexroom has raised $50 million in a Series B funding round led by Left Lane Capital. The round also included participation from Base10 Partners, Eurazeo, Acurio Ventures, Entourage, and View Different.
The investment comes only eight months after the company’s Series A financing and brings Lexroom’s total funding to more than $73 million.
A Different Approach to Legal AI
Unlike many AI tools that rely heavily on fine tuned general purpose language models, Lexroom has built its platform around what it describes as a data first architecture focused on verified legal materials.
The company argues that traditional generative AI systems often struggle with reliability in legal environments because they can produce fabricated citations, inaccurate references, or unverifiable outputs. In legal practice, where precision and source verification are essential, those limitations create serious risks for professionals and organisations.
To address this, Lexroom built a proprietary legal database containing more than six million verified legal sources. The platform continuously updates and structures legislation, case law, and regulatory materials to support legal research, drafting, and retrieval tasks.
According to the company, grounding outputs directly in verified source material allows the platform to align more closely with real legal workflows while reducing the risk of hallucinated or inaccurate information.
Building AI for Civil Law Systems
Paolo Fois said the company was founded on the belief that lawyers needed a significantly more efficient way to work and that large language models alone were not sufficient to meet the requirements of legal practice.
Fois explained that the missing layer was always updated legal data combined with legal reasoning systems designed specifically for civil law jurisdictions. He argued that civil law countries require AI infrastructure capable of reasoning directly on structured legal information rather than relying purely on general purpose AI generation.
This focus differentiates Lexroom from many legal AI startups initially built around Anglo American common law systems.
Rapid Adoption Across Legal Teams
Lexroom says its platform is now used by more than 8,000 law firms and corporate legal teams, with the majority of users engaging with the platform daily.
The company aims to help legal professionals reduce the amount of time spent on legal research, drafting, and document analysis while maintaining professional quality standards and regulatory compliance.
As legal workloads continue increasing across firms and corporate legal departments, AI tools capable of improving efficiency without sacrificing reliability are attracting growing attention from the legal industry.
Expansion Across Europe
The newly secured funding will support Lexroom’s next stage of European expansion, beginning with Spain and Germany.
The company plans to build local operational teams while developing jurisdiction specific legal capabilities tailored to the regulatory and legal frameworks of each market. Lexroom says it will collaborate closely with local law firms and legal professionals to adapt its platform for regional legal systems and workflows.
The Growing Market for Legal AI Infrastructure
As artificial intelligence adoption accelerates across professional services industries, the legal sector is emerging as one of the most strategically important markets for trusted AI infrastructure. Law firms increasingly require systems capable of combining automation and productivity gains with strict professional accuracy and compliance standards.
By focusing on verified legal data, source grounded reasoning, and jurisdiction specific legal workflows, Lexroom is positioning itself as part of a new generation of AI companies building specialised infrastructure for the future of legal work across Europe.
