Bretton AI, a US-based RegTech specialising in AI agents for financial crime compliance, has raised funding of $75m in a Series B.
The company, formerly known as Greenlite AI, said its rebrand reflects a broader ambition to shape how AI is governed and deployed inside regulated financial institutions.
The company has secured $75m in a Series B funding round led by Sapphire Ventures, with continued backing from existing institutional investors Greylock, Thomson Reuters Ventures, Canvas Ventures and Y Combinator.
TIAA Ventures joined as a new investor. As part of the transaction, Sapphire Ventures partner Rajeev Dham has taken a seat on Bretton AI’s board. The financing comes less than a year after the company closed its Series A.
Bretton AI’s platform is designed to automate high-volume, mission-critical financial crime workflows. Its AI agents support regulated banks and financial platforms with tasks such as KYC and KYB reviews, AML and sanctions investigations, and ongoing monitoring.
Customers include OCC-, FDIC- and Federal Reserve-regulated banks, as well as global platforms such as Robinhood, Mercury, Gusto, Lead Bank and Coastal Community Bank. At the centre of the system is what the company calls its proprietary Trust Infrastructure, which embeds regulatory guidance, model risk management and continuous evaluation into each AI agent to ensure outputs are audit-ready and explainable.
The new capital will be used to extend the platform into additional financial crime domains, deepen engagement with regulators and accelerate adoption among larger, more complex institutions. Bretton AI also plans to increase investment in product development while expanding its engineering and go-to-market teams.
Since its Series A in May 2025, the company said it has seen rapid growth in adoption, including signing five new publicly traded companies in 2025. It claims the total market capitalisation of companies relying on its platform has risen from $150bn to more than $1tn over the past year.
Average contract values have climbed to $201,000, up from $85,000 at the time of the Series A and $25,000 at seed stage in 2023. Bretton AI said its agents have now completed more than 1.2 million L1 and L2 financial crime investigations, helping customers eliminate over 195,000 hours of manual compliance work and save more than $10m in compliance-related headcount and risk costs.
Case studies cited by the company include a $15bn-plus financial institution that reduced BPO spending by $5.35m in its first year using the platform, a Fortune 500 company that cut institutional onboarding times by 50%, and an FDIC-regulated bank that reduced loan origination timelines by up to 90%.
Bretton AI CEO and co-founder Will Lawrence said, “Financial crime is the breakout use case for AI in financial services. This work is complex, unstructured, and deeply scrutinized. We’ve proven that AI agents can operate in production inside the world’s most regulated institutions when built with the right trust and governance foundations. Bretton AI represents the next chapter of that ambition.”
Explaining the name change, Lawrence added, “Greenlite AI was about proving that trusted AI agents could work in compliance. Bretton AI is about defining the standard for how AI operates inside regulated financial institutions. Our mission has expanded, and our name needed to reflect that.”
He also said, “They need systems built from the ground up for regulatory accountability. The opportunity to help financial institutions operate more safely and efficiently without compromising that trust is enormous. Bretton AI exists to define the industry standard for trustworthy, audit-ready AI in the financial system.”
