Our take

Identity and payment fraud is one of the biggest dangers facing online businesses. Sardine is setting out to solve this problem by building the first zero-day fraud prevention technology.

Sardine's technology traces intrinsic behaviour patterns to identify so-called "bad actors" online, and detects fraudsters using machine-learned fraud scores and user behavior biometrics.

The company calls itself the world's first FaaS (Fraud Detection as a Service), and its solutions are already drawing business from next-gen crypto and financial service institutions. Onboarding these institutions and scaling its customer base at pace will ensure that Sardine maintains its frontrunner position.
