Left Lane Capital led the Milan-based startup’s Series B, eight months after its $19m Series A. Lexroom offers a verified-source legal AI built around six million documents.
Milan-based Lexroom, the legal AI startup focused on civil-law jurisdictions, has secured $50m in Series B funding led by Left Lane Capital. Base10 Partners, Eurazeo, Acurio Ventures, Entourage, and View Different also participated in the round, which closed eight months after the company’s $19m Series A, bringing its total funding past $73m. Proceeds will support expansion into Spain and Germany.
Lexroom’s offering is more focused than the broader legal AI category, typically pitched as general-purpose tools. Its product centers on a proprietary database of over six million verified legal sources, including legislation, case law, and regulatory materials, all maintained and structured for efficient retrieval.
The company emphasizes a "data-first" architecture, contrasting with fine-tuned general-purpose language models that have struggled with reliability issues in legal AI, such as fabricated citations, inaccurate references, and uncheckable outputs.
"When we started Lexroom, two things were immediately clear," said Paolo Fois, CEO and co-founder, in a statement. "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."
Lexroom positions itself against the dominant US-trained, common-law-based legal AI category that has attracted significant venture capital investment through 2024 and 2025, with companies like Harvey, Hebbia, and EvenUp raising large valuations primarily serving an English-language, US and UK customer base.
The key distinction lies in Lexroom’s civil-law focus. Civil-law systems, prevalent in continental Europe, Latin America, and parts of Asia, rely on codified statutes as primary sources of authority, unlike the US, where judicial precedent plays a significant role. Lexroom argues that its verified-source approach is better suited to civil-law practices.
Lexroom claims its platform is used by over 8,000 law firms and corporate legal teams, with most users engaging daily. However, the company did not disclose revenue, customer retention rates, or specific customer mix.
Just eight months after its Series A, Lexroom’s rapid growth underscores the potential for civil-law legal AI in a global market.
