Bretton AI Raises $75 Million Series B to Scale Financial Crime Compliance Platform
Bretton AI, formerly known as Greenlite AI, has raised $75 million in Series B funding to expand its artificial intelligence platform for financial crime compliance. The round was led by Sapphire Ventures, with continued participation from existing investors Greylock, Thomson Reuters Ventures, Canvas Ventures, and Y Combinator. New investor TIAA Ventures also joined the round.
The company has rebranded from Greenlite AI to Bretton AI, with the new name honouring the Bretton Woods agreement that shaped the modern financial system. The rebrand reflects an expanded mission: from proving AI could work in compliance to establishing the standard for how AI operates within regulated institutions.
What Bretton AI does
The platform deploys AI agents to handle complex financial crime workflows including Know Your Customer (KYC) and Know Your Business (KYB) reviews, Anti-Money Laundering (AML) investigations, sanctions screening, and ongoing customer monitoring.
Bretton AI's agents have completed more than 1.2 million L1 and L2 financial crime investigations, helping customers save over $10 million in compliance-related headcount costs while eliminating more than 195,000 hours of manual compliance work.
Growth trajectory
Since its $15 million Series A in May 2025, the company has seen significant expansion. The total market capitalisation of its customer institutions has grown from $150 billion to over $1 trillion. Average contract value has increased from $85,000 at Series A to $201,000 — up from $25,000 at seed stage in 2023. In 2025, Bretton AI signed five new publicly traded companies as customers.
"This work is complex, unstructured and deeply scrutinised," said CEO Will Lawrence. "AI agents can operate in production inside the world's most regulated institutions."
Use of funds
The Series B funding will be used to expand across additional financial crime domains, deepen regulatory engagement, and accelerate adoption among larger and more complex institutions. Total capital raised now stands at approximately $95 million.
