What Is Luminance?
Luminance was founded in 2015 by Emily Foges and spun out of the University of Cambridge's machine learning research group. The company has raised over $120 million and serves more than 600 organizations across 70+ countries. Luminance's core technology uses unsupervised machine learning to read and understand legal documents — meaning it does not need to be trained on specific contract types to analyze them.
The platform's signature capability is high-volume document review. In an M&A due diligence exercise that would take a team of lawyers weeks, Luminance can process thousands of documents in hours, identifying key terms, unusual clauses, hidden risks, and inconsistencies across the document set. The AI understands legal concepts across multiple languages and jurisdictions.
In 2026, Luminance has expanded beyond review into contract negotiation (Luminance Autopilot) — an AI that can autonomously negotiate contract terms through email, applying your negotiation playbook to incoming redlines.
