Lexroom.ai develops AI infrastructure for legal professionals using a data-first approach grounded in a proprietary database of over six million verified legal sources, including legislation, case law and regulatory materials. The platform is designed to reduce fabrications and reliability issues in generative AI by structuring continuously updated source material for legal research and retrieval. Lexroom reports more than 8,000 law firm and corporate legal team customers, with most users engaging daily. Financially, the company has raised over $73 million to date after closing a $50 million Series B led by Left Lane Capital. The new capital will fund expansion into civil law markets across Europe, starting with Spain and Germany, and support building local teams and jurisdiction-specific capabilities in partnership with firms in those markets.
