We combine sequential transaction data, device intelligence, behavioral biometrics, and identity signals across Sardine’s global network. The goal is simple: turn research advances into measurable protection against financial crime. ## Built on the fastest-growing dataset in financial crime Our research starts with the breadth of Sardine’s network and goes deep into the sequence of each customer’s financial behavior. - 7.8B: Devices profiled - 441M: Consumer identities - 3.1M: Businesses screened - 5.46B: Transactions analyzed - $1.6T: Transactions protected ## Four questions shaping our work Financial crime is sequential, adaptive, and connected. Our research agenda is built around those realities. ## A stronger signal from the history already there Our first payments foundation model learned from unlabeled transaction sequences, then supplied new features to the issuing fraud model already in production. - 24–35%: more fraud caught at the same share of transactions flagged for action - 68%: improvement in overall ranking quality, measured by AUC-PR - 29%: improvement for a client population held out of pretraining ## Bring us the hard problems We want to widen who gets to work on financial crime research and make meaningful progress easier to measure. ## Ideas, methods, and evidence Read the work behind the numbers and follow the questions we are investigating next. ## The next breakthrough in fighting financial crime may start outside our walls
