What is Luminance?
Luminance is a contract intelligence platform that reads an organization's contracts and turns them into usable information on risk, obligations and commercial opportunities. It covers three main areas. Negotiate applies playbooks and precedent during contract review. Discover lets teams query their contract portfolio. Automate runs connected workflows from intake to signature.
Its AI combines legal data, encoded legal expertise and purpose-built intelligence to understand contracts and validate its conclusions.
The platform combines specialist legal models with contractual context. Its components include a document search engine, a repository and an assistant called Luna. Luminance was founded by researchers from the University of Cambridge and says it has worked on contract intelligence for over a decade.
It is built for large enterprises. Legal, procurement, finance, sales, HR, compliance and executive teams can all use it. Security credentials include ISO 27001 certification, SOC 2 Type II examinations and independent penetration testing. Pricing is not published, so access starts with a demo request.
