Luminance

What we found

Luminance is an AI contract platform that in September 2026 relaunched itself as "Contract Intelligence" for whole organisations — legal, procurement, finance, sales and HR — rather than only lawyers. It negotiates contracts against a company's playbooks, precedents and preferred clauses, proposing context-aware redlines directly in Microsoft Word; lets users ask its assistant, Lumi, questions across an entire contract portfolio with source-backed answers; and automates contract workflows, with integrations for DocuSign, Outlook and Word and support for MCP. It runs on its own legal models, including Luna Crescent, launched in June 2026, which it says is four times faster than general frontier models and more accurate in blind tests by legal experts, figures from its own benchmarks, inside a multi-model architecture on infrastructure it controls. It holds ISO 27001 and SOC 2 Type II certification.

Luminance Technologies Ltd was founded in Cambridge, England, in 2015 by mathematicians Adam Guthrie and Graham Sills, and is led by chief executive Eleanor Lightbody, with offices in London, New York, San Francisco, Dallas, Toronto, Vancouver and Sydney. It raised a $75 million Series C led by Point72 Private Investments in February 2025, bringing total funding to about $165 million, and says more than 1,000 organisations in over 70 countries use it, naming AMD, LG Chem, TotalEnergies, NTT Data, Yokogawa and the law firm Clyde & Co. Customer case studies on its site report large savings, such as a 90 per cent cut in outside-counsel costs at Imerys.

Luminance does not publish prices; it is sold by quote after a demo, and prospective customers can run a free proof-of-value evaluation under its terms rather than a self-serve trial. There is no free or self-serve plan.

Independent review volume is small: G2 lists ten reviews, nine of them incentivised, averaging 4.6, and Gartner Peer Insights shows 4.6 from 27 ratings. Luminance suits mid-size and large organisations wanting AI-assisted contract negotiation across departments.
