Luminance

The company's core technology, "Legal-Grade™ AI," is built on a proprietary legal Large Language Model (LLM) and employs a "Mixture of Experts" (MoE) approach, which it calls the "Panel of Judges". This system uses multiple specialized AI models that work together to automate and augment every stage of the contract lifecycle, from initial drafting and negotiation to post-execution analysis and repository management. Luminance's platform provides tools like AI-powered negotiation, an intelligent document repository, a legal-grade chatbot named "Ask Lumi," and business-wide automation capabilities. Its products can analyze documents to identify risks, ensure compliance, and extract key information, integrating with common business software like Microsoft Word.

Luminance operates on a B2B Software-as-a-Service (SaaS) business model, serving law firms and corporate legal departments. Clients pay subscription fees based on usage or number of users, with enterprise agreements for larger customers. The company serves over 700 organizations in more than 70 countries, including prominent clients like AMD, Hitachi, LG Chem, Rolls-Royce, and Lamborghini, as well as over a quarter of the world's top 100 law firms such as Clifford Chance and White & Case. The company is led by CEO Eleanor Lightbody, who joined in 2021. In early 2025, Luminance secured $75 million in a Series C funding round led by Point72 Private Investments, bringing its total funding raised to over $165 million.
