Luminance Adds Memory to Legal AI Platform

Luminance launched institutional memory for its legal AI on January 27, retaining negotiation history across enterprise contracts.

London-based Luminance announced its largest product update in ten years on January 27, 2026, introducing institutional memory capabilities that retain negotiation history and legal decision-making across all enterprise contracts. The update, piloted with Deloitte, Quantinuum, Ingram Micro, and Baringa, will be broadly available from February 25. The company doubled its global revenue in 2025 for the second consecutive year and increased headcount by 40%.

Enterprise contract systems capture negotiation outcomes but lose the context behind decisions. Eleanor Lightbody, CEO of Luminance, said institutional memory "transforms legal AI from a legal tool into the central brain for the entire enterprise." The update addresses what the company calls "enterprise amnesia," where critical context disappears when executives need to understand past contract decisions.

Memory Architecture

The platform uses what Luminance calls "recursive legal context engineering." Graham Sills, co-founder and director of AI at Luminance, explained the system can pull in customer history and other information on demand as it processes queries. The multi-agent architecture operates across every contract lifecycle stage, drawing on short-term memory from previous reasoning steps and long-term memory embedded in the platform.
