- Milan-based Lexroom has closed a $50 million Series B led by Left Lane Capital, eight months after its $19 million Series A, bringing total funding to over $73 million
- The platform serves more than 8,000 law firms across Europe, built on a proprietary database of six million verified legal documents designed specifically for civil law jurisdictions
- The raise takes on Harvey, valued at $11 billion, and Swedish rival Legora, valued at $5.55 billion, by targeting the structural gap that generic legal AI leaves across continental Europe
Milan-based Lexroom has closed a $50 million Series B to bring AI-powered legal research to continental Europe’s largely underserved legal market and take on the US giants dominating the space.
The round was led by Left Lane Capital, with participation from Base10 Partners, Eurazeo, Acurio Ventures, Entourage, and View Different. It comes eight months after a $19 million Series A, bringing total funding to over $73 million. The company says it now serves more than 8,000 law firms and corporate legal teams.
The legal AI market it is entering is already crowded and expensive. Harvey raised $300 million in a 2025 Series D at a $3 billion valuation, then raised again in 2026 at an $11 billion valuation. Swedish competitor Legora closed a $550 million Series D in 2026 at a $5.55 billion valuation. Both are heavily focused on common-law markets: the US and UK, where legal reasoning centres on case precedent.
Founded in 2023 by Paolo Fois, Martina Domenicali, and Andrea Lonza, Lexroom was built around a structural problem that many global legal technology companies have struggled to solve. Most legal AI platforms were designed for common-law systems such as the US and UK, where legal reasoning relies heavily on precedent-based case law.
Continental Europe works differently. Civil law systems are built on codified statutes and jurisdiction-specific procedures, and require localised legal datasets, multilingual reasoning, and country-specific compliance infrastructure. That gap is what Lexroom is betting on.
Rather than fine-tuning a general-purpose model, the company built its own legal data infrastructure first, a proprietary database of more than six million verified documents spanning legislation, case law, court rulings, and regulatory materials across European jurisdictions. Every output cites a traceable source, a design decision that matters in a market where AI-generated hallucinations have resulted in court sanctions, six-figure fines, and public apologies from top-tier law firms to federal judges.
In under 18 months, the company grew ARR more than twelvefold and headcount from 30 to 90, with a target of 200 by end of 2026. The new capital funds expansion into Spain and Germany, where Lexroom plans to rebuild its data infrastructure from scratch for each jurisdiction rather than translate its Italian product.
“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,” says 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,” said Paddy Dillon, VP at Left Lane Capital.
