What is Luminance?

Luminance was spun out of the University of Cambridge in 2015, applying pattern-recognition ML to contract review long before LLMs were practical. It has since added Corporate (a contract negotiation product) and Lumi (a chat-style legal assistant) and now serves 700+ corporates and law firms across 70 countries — one of the largest legal AI footprints by customer count. Strong in EU and Commonwealth jurisdictions; weaker brand presence in US AmLaw than Harvey.
