Bretton AI has raised fresh capital as it rebrands from Greenlite AI and broadens its ambition to set a new benchmark for how artificial intelligence is deployed across regulated financial institutions.
The company secured $75m in a Series B round led by Sapphire Ventures, with continued backing from Greylock, Thomson Reuters Ventures, Canvas Ventures and Y Combinator.
TIAA Ventures joined as a new investor, and Rajeev Dham, partner at Sapphire Ventures, has taken a seat on Bretton AI’s board. The financing comes less than a year after its Series A.
Bretton AI develops AI agents designed to handle high-volume, mission-critical financial crime workflows. Its technology is already in use at banks regulated by the OCC, FDIC and Federal Reserve, as well as global financial platforms including Robinhood, Mercury, Gusto, Lead Bank and Coastal Community Bank. The platform supports processes such as KYC and KYB reviews, AML and sanctions investigations, and ongoing transaction monitoring.
At the heart of its system is a proprietary “Trust Infrastructure”, which embeds regulatory guidance, model risk management and continuous AI evaluation into every agent. The company says this ensures its tools are audit-ready, explainable and aligned with supervisory expectations from the outset. Its agents operate across multiple systems, synthesising fragmented data and completing investigations in minutes rather than days, helping institutions reduce manual workloads while maintaining regulatory standards.
The new funding will be used to expand the platform into additional financial crime domains, strengthen engagement with regulators and accelerate adoption among larger and more complex institutions. Bretton AI also plans to increase investment in product development and scale its engineering and go-to-market teams.
Since its Series A in May 2025, Bretton AI says adoption has accelerated. The combined market capitalisation of companies using its platform has grown from $150bn to more than $1tn in the past year. In 2025, it signed five new publicly traded companies, while average customer contract value rose to $201,000, up from $85,000 at Series A and $25,000 at Seed in 2023. The firm says it has helped clients save more than $10m in compliance-related headcount costs and eliminated over 195,000 hours of manual work. Its agents have completed more than 1.2 million L1 and L2 investigations.
Will Lawrence, CEO and co-founder of Bretton AI, 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 said, “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 added, “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.”
