A Cambridge-born legal AI company whose software reads, reviews and negotiates contracts. It aims to make every contract work harder for the organisations that use it.
Luminance is a legal technology company that uses artificial intelligence (AI) to help organisations understand and manage their contracts. Its software reads contract language, helps teams spot risk, track promises and negotiate, and turns what is in legal documents into useful business information. The company says it has more than 1,000 customers, operations in over 70 countries, and 220 million-plus legally verified documents behind its AI.
Luminance describes itself as born out of the University of Cambridge. Fortune reports it was founded in 2015 by Cambridge mathematicians, and Legal Technology reports a start in September 2015 using Cambridge research in language processing, machine learning and probability. Eleanor Lightbody is now chief executive and Adam Guthrie is a founder and chief technical architect (Fortune, 2024). An earlier chief executive, Emily Foges, joined in 2016 when it was a small team of technologists and lawyers. It was a Cambridge and London business with about 25 staff in 2017 and has since opened a US office in Dallas; the UK is its home base. It won a Queen's Award for Enterprise for innovation.
Its goal, in its own words, is to make every contract work harder, and it says contracts are everyone's business. Its multi-agent platform learns from negotiations and applies that context across the contract lifecycle. It calls its approach Legal-Grade AI: specialist models built for legal language, with validation steps and audit trails so humans can check the work. It also stresses institutional memory, learning from an organisation's own contracts so that knowledge is not lost.
The first customers were law firms, which used it for due diligence, the careful checking of documents before a company deal. It now targets corporate teams as well, because contract intelligence is useful beyond the legal department. Products named by Fortune include Ask Lumi, a chatbot that answers contract questions and redrafts wording, and Agent Lumi, an assistant that can mark up and amend agreements, with each step open to audit. A Luminance developer interviewed by the St Andrews Law Review described building features such as Knowledge Banks in a Cambridge application engineering team that values code review and testing.
Luminance says it values intellectual curiosity, clear thinking and confidence in challenging established ways of working, and its team mixes AI, maths, engineering, law and business expertise. Roles include machine learning, software engineering, legal engineering, sales and customer success. One advertised eight-week AI engineering internship was based in Cambridge, with three or more office days a week, asking for a First or 2:1, preferably in a technical subject, and pay described as equivalent to a competitive graduate salary with no figure given. We found no formal graduate scheme, so check its careers page.
