## Company Overview

Bretton AI (formerly Greenlite AI) is a financial crime compliance platform that deploys AI agents to automate the manual investigation workflows inside bank anti-money laundering (AML) operations. The company raised $75 million in Series B financing in February 2026 and simultaneously rebranded to signal a category-defining ambition — the "Bretton Woods of financial crime AI." Backed by Greylock, Sapphire Ventures, Y Combinator, and Thomson Reuters Ventures, average contract values grew from $85,000 to $201,000 between the Series A and B, reflecting expansion into larger bank customers.

The platform deploys AI agents that handle the full AML investigation lifecycle: transaction alert triage, case creation, evidence collection, SAR (Suspicious Activity Report) drafting, and compliance documentation — tasks that currently require large teams of human analysts at every regulated financial institution. Banks whose combined market capitalizations have grown from $150 billion to $1 trillion+ in the customer base within one year demonstrates rapid enterprise penetration at the largest institutions.

Thomson Reuters Ventures' backing is strategically significant: Thomson Reuters operates Westlaw and other legal and compliance research databases that are standard references in AML investigations. The co-investment suggests potential product integration between Bretton's AI agents and Thomson Reuters' compliance data, creating a combined offering with broad institutional adoption pathways.
