Lexroom raises $50 million to accelerate European legal AI expansion
Artificial intelligence applied to the legal sector continues to attract significant investment. Italian legal tech company Lexroom has closed a $50 million Series B round led by Left Lane Capital, with participation from Base10 Partners, Eurazeo, Acurio Ventures, Entourage and View Different.
The transaction comes less than a year (eight months, to be precise) after the company’s previous $19 million raise, bringing total funding to more than $73 million. The new capital will support expansion across Europe’s main civil law markets, starting with Spain and Germany. Completion of the deal remains subject to the Italian government’s Golden Power approval process.
Founded by Paolo Fois, Martina Domenicali and Andrea Lonza, Lexroom develops artificial intelligence tools for law firms and in-house legal teams. The company says it currently serves more than 8,000 professional users on its platform. Usage figures indicate that 65% of users access the platform daily, while 94% use it at least once a week.
The funding round comes at a time of rapid growth for legal AI, but also amid increasing scrutiny around the reliability of generative AI technologies applied to legal work. In recent months, the issue has become particularly sensitive in both the United States and Europe following several court filings containing fictitious legal references generated by AI systems. Those incidents have reinforced concerns within parts of the legal profession about tools relying exclusively on general-purpose large language models.
Lexroom is attempting to differentiate itself precisely on this point. The company has built its platform around a proprietary database of legal and regulatory sources, now exceeding six million documents, which are used as the foundation for legal research and AI-assisted drafting activities.
The stated objective is to reduce the time spent on lower-value tasks (including legal research, document analysis and first-draft preparation) in a sector historically characterized by limited automation.
For investors, the opportunity lies primarily in the European civil law market, which has so far remained less penetrated by large international legal AI platforms compared with the Anglo-Saxon market. The sector includes more than one million lawyers and remains highly fragmented, particularly among small and mid-sized firms.
Italy has served as Lexroom’s initial testing ground, partly due to the size of the domestic legal market and the complexity of the country’s regulatory framework, with approximately 250,000 registered lawyers. With the new funding, the company now aims to replicate its model across other European jurisdictions, developing features tailored to local legal systems and regulations.
“When we founded Lexroom, two things were immediately clear: lawyers needed a better way to work, and LLMs could help provide it. The missing piece was data — constantly updated legislation, relevant case law and court filings. Civil law countries need an AI legal engine built around data,” said Paolo Fois, CEO and co-founder of Lexroom, in a statement released by the company.
Paddy Dillon, vice president at Left Lane Capital, added: “Paolo, Martina and Andrea have built something rare: an enterprise product with the engagement levels of a consumer app, in a market that still moves through committees and formal approvals. What convinced us was Lexroom’s ability to help lawyers build stronger firms, serve clients more effectively and turn AI into an ally rather than a threat.”
