About
Luminance is an AI legal technology company founded in 2016 in Cambridge, UK by mathematicians from the University of Cambridge, and has raised over $100M to develop AI that reads, understands, and negotiates legal documents. The company's platform uses proprietary large language models trained specifically on legal data to analyze contracts, identify risks, compare documents against playbooks, and now negotiate changes through its Autopilot feature that can conduct contract negotiations end-to-end with minimal human oversight. Luminance serves both law firms and in-house corporate legal teams, offering tools for due diligence, contract review, regulatory compliance, and NDA management. The company has customers in over 70 countries and processes millions of legal documents across financial transactions, M&A due diligence, and commercial contracting. Luminance positions itself as legal AI that truly understands law rather than pattern-matching on text, drawing on its Cambridge mathematics heritage to develop AI with deeper semantic understanding of legal language and concepts. The platform has become particularly prominent in financial services and real estate transactions requiring large-scale document review.
