Sardine operates a fraud and compliance platform built around behavior biometrics, device intelligence, and machine learning. The platform is designed to detect and prevent identity fraud, payment fraud, account takeovers, and social engineering scams before transactions complete - rather than flagging them after the fact. It serves over 300 banks, retailers, and fintechs across more than 70 countries, securing upward of $150 billion in payments and stopping over $21 billion in fraud attempts.
The company was founded by Soups Ranjan, a data scientist who previously worked on fraud prevention at Coinbase and Revolut. The founding was shaped in part by observing over a million dollars lost to identity fraud in 2020. That background informs the platform's core approach: combining behavioral signals - how a user moves, types, and interacts with a device - with AI-driven risk modeling to surface fraud patterns that conventional rule-based systems miss.
Sardine has raised $145 million in funding from investors including Andreessen Horowitz, Visa, and Google Ventures. The technical domains its teams work across include machine learning, AI, behavior biometrics, device intelligence, and payment security, with ongoing development on its AI risk platform.
