- 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 more than $73 million.
- The platform serves over 8,000 law firms across Europe and is built on a proprietary database of 6 million verified legal documents designed specifically for civil law jurisdictions.
- The raise targets the structural gap that general-purpose legal AI leaves across the continent, taking on Harvey, which has a market capitalization of $11 billion, and its Swedish rival Regola, which has a market capitalization of $5.55 billion.
Milan-based Lexroom has closed a $50 million Series B to bring AI-powered legal research to largely underserved legal markets in continental Europe and take on the large U.S. firms that dominate the space.
The round was led by Left Lane Capital with participation from Base10 Partners, Eurazeo, Acurio Ventures, Entourage, and View Different. This comes eight months after a $19 million Series A, bringing total funding to more than $73 million. The company currently serves more than 8,000 law firms and corporate legal teams.
The legal AI market the company is in is already crowded and expensive. Harvey raised a $300 million Series D in 2025 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 valuation of $5.55 billion. Both focus on common law markets, namely the US and UK, and their legal reasoning focuses on case law.
Founded in 2023 by Paolo Fois, Martina Domenicali, and Andrea Lonza, Lexroom was built around a structural problem that many global legal technology companies struggle to solve. Most legal AI platforms are designed for common law systems such as the US and UK, where legal reasoning relies heavily on precedent-based case law.
It works differently in continental Europe. Civil law systems are built on codified statutes and jurisdiction-specific procedures and require localized legal datasets, multilingual reasoning, and country-specific compliance infrastructure. This gap is what Lexroom is betting on.
Rather than fine-tuning a generic model, the company first built its own legal data infrastructure. It is a unique database of over 6 million verified documents spanning legislation, case law, court decisions, and regulatory materials across European jurisdictions. All output cites traceable sources and cites important design decisions in a market where AI-generated hallucinations have resulted in court sanctions, six-figure fines, and public apologies from top law firms to federal judges.
In less than 18 months, the company grew ARR more than 12x and increased its headcount from 30 to 90, with a goal of 200 by the end of 2026. The new capital funding will also extend to Spain and Germany, where Lexroom will rebuild its data infrastructure from the ground up for each jurisdiction rather than translate its Italian product.
“When we launched Lexroom, two things quickly became clear: Lawyers need a better way of working, and LLMs can provide that. What was missing was data, constantly updated laws, relevant case law, and litigation procedures. Civil law countries need an AI legal engine that prioritizes data and makes inferences,” said Paolo Fois, CEO and co-founder of Lexroom.
“Paolo, Martina and Andrea have built an enterprise product with consumer-level user attachment and engagement, which is highly unusual in an industry that is often sold through innovation boards,” said Paddy Dillon, vice president at Left Lane Capital.
