Lexroom announced it raised $50 million in Series B funding led by Left Lane Capital, with participation from Base10 Partners, Eurazeo, Acurio Ventures, Entourage, and View Different. The funding round comes eight months after the company’s $19 million Series A and brings Lexroom’s total funding to more than $73 million.
Founded in Milan in 2023, Lexroom is building an AI platform designed specifically for civil law jurisdictions across Europe. The company said the new funding will support expansion into Spain and Germany while continuing development of jurisdiction-specific legal AI capabilities.
Lexroom said its platform is built using a data-first approach rather than relying on fine-tuned general-purpose large language models. The company has developed proprietary infrastructure containing more than 6 million verified legal sources, including legislation, case law, and regulatory materials, continuously updated for legal research and retrieval.
The company pointed to growing concerns surrounding AI hallucinations in the legal industry, citing more than 1,300 documented court filings containing fabricated citations, non-existent precedents, and inaccurate legal references. Lexroom said its platform was designed to enable lawyers to verify and trace outputs directly to their original legal sources.
Lexroom currently serves more than 8,000 law firms and corporate legal teams across Europe. According to the company, two-thirds of users are daily active users and 94% use the platform weekly.
The company said the platform is helping lawyers complete legal research, drafting, and analysis more efficiently while allowing firms to handle more client work without lowering professional standards. Lexroom added that most of Europe’s more than one million lawyers operate in solo or small firms, making workflow efficiency particularly important across the region’s legal system.
Italy served as Lexroom’s initial proving ground because of its large legal market and procedural complexity. The company said the new funding will accelerate its expansion throughout civil law Europe with localized teams and legal capabilities developed for each jurisdiction.
KEY QUOTES:
“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. Excited to partner with the Left Lane team to build the AI backbone of the legal industry.”
Paolo Fois, CEO And Co-Founder of Lexroom
“Paolo, Martina and Andrea have built an enterprise product with consumer-grade user love and engagement, which is exceedingly rare in an industry that is often sold to through innovation committees. We loved that Lexroom enables lawyers to build better businesses by serving their clients more thoughtfully and effectively, making AI friend not foe.”
Paddy Dillon, VP at Left Lane Capital
