About
Lexion is a Seattle-based contract management platform that uses AI to extract, organize, and surface key information from executed contracts. The platform automatically reads uploaded contracts and populates structured data fields — parties, dates, renewal terms, payment obligations — enabling teams to search and report across their entire contract portfolio without manual entry. Lexion targets in-house legal and operations teams at mid-market companies that need contract visibility but cannot afford enterprise CLM complexity. Founded in 2018 and backed by Khosla Ventures, Lexion integrates with Google Drive, Dropbox, and Salesforce. Its smart inbox feature routes incoming contracts to the correct owner and tracks negotiation status across email threads, closing the gap between contract data and business action.
Luminance is an AI legal platform using large language models to read, understand, and negotiate contracts, serving law firms and corporate legal teams globally.
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.
