Milan-based Lexroom has closed a $50 million Series B led by Left Lane Capital, just eight months after its $19 million Series A, bringing its legal AI platform to more than 8,000 law firms and in-house teams across Europe. Base10 Partners, Eurazeo, and Acurio Ventures also participated.
Founded in 2023 by CEO Paolo Fois, Martina Domenicali, and Andrea Lonza, Lexroom argues that general-purpose large language models are fundamentally unsuitable for legal work — a position backed by more than 1,300 court filings already identified as containing AI-fabricated citations and non-existent precedents. Instead, the platform is built on proprietary infrastructure drawing from over six million continuously updated verified legal sources including legislation, case law, and regulations.
Left Lane VP Paddy Dillon said the combination of enterprise-grade capability and exceptional user experience was rare in a sector typically sold through innovation committees. Two-thirds of users access the platform daily. The Series B will fund expansion into Spain and Germany, following Italy’s 250,000-strong lawyer market as its proving ground.
