Milan-based legal AI company Lexroom has raised $50 million in a Series B funding round led by Left Lane Capital, with participation from Base10 Partners, Eurazeo, Acurio Ventures, Entourage and View Different. The round comes eight months after the company’s Series A and brings Lexroom’s total funding to more than $73 million.
Lexroom develops AI infrastructure for legal professionals, focusing on a data-first approach built around verified legal sources rather than fine-tuned general-purpose language models. The company says its platform is designed to address reliability and verification challenges associated with generative AI tools in legal work, including fabricated citations and inaccurate legal references.
Its platform is built on a proprietary database of more than six million verified legal sources, including legislation, case law and regulatory materials, which are continuously updated and structured for legal research and retrieval. Lexroom says this architecture is designed to align more closely with legal workflows by grounding outputs directly in source material.
When we started Lexroom, two things were immediately clear: lawyers needed a better way to work, and LLMs could deliver it. The missing piece was data - always-updated laws, relevant case law and legal proceedings. Civil law countries need an AI legal engine that reasons data-first,
said Paolo Fois, CEO and co-founder of Lexroom.
The platform is now used by more than 8,000 law firms and corporate legal teams, with a majority of users engaging with the product on a daily basis. Lexroom aims to reduce the time required for legal research and drafting, allowing firms to handle more work while maintaining professional standards.
The new funding will support the company’s expansion across civil law jurisdictions in Europe, beginning with Spain and Germany. Lexroom plans to build local teams and develop jurisdiction-specific capabilities in collaboration with firms operating in those markets.
