Sandbar builds performant anti-money laundering (AML) software to more accurately identify illegal activity. Criminals launder an estimated $4 Trillion every year, yet less than 1% of this is caught. To provide better results, we ingest millions of messy data points, standardize that data, and run a complex suite of proprietary calculations designed to detect suspicious activity. Our product automatically monitors activity and empowers risk teams by putting necessary information at their fingertips. We provide information accessibility, build intuitive workflows, and allow for custom processing. Doing better can help cut off funding for kidnappers, human traffickers, terrorists, scammers, and other bad actors as well as reduce the effort and costs associated with developing and maintaining internal AML programs. We are a small but growing team that values creativity, collaboration, and innovation. We're backed by Lachy Groom, Abstract Ventures, BoxGroup, and over 40 other founders, early employees, and executives of Ramp, OpenAI, Stripe, Square, Plaid, and more.
