Sardine is a fraud prevention and compliance infrastructure platform that has carved out a strong niche serving crypto companies, fintech firms, and traditional financial institutions. Founded by Soups Ranjan, formerly Head of Data Science at Revolut, the team brings deep expertise in behavioral biometrics and device intelligence to detect fraudulent transactions in real time.

The platform's core strength lies in its sophisticated risk scoring engine that analyzes thousands of data points—including typing patterns, device signals, and transaction behavior—to identify fraud before it occurs. This is particularly valuable in crypto, where chargebacks and account takeover attacks remain persistent threats. Sardine also offers a fiat-to-crypto on-ramp, enabling instant ACH payments with reduced fraud risk, which addresses a major pain point for exchanges and NFT marketplaces.

On the compliance side, Sardine provides robust KYC/KYB and AML screening tools, helping clients navigate increasingly complex regulatory landscapes. The company has secured significant venture funding from notable investors including a]Andreessen Horowitz and Visa.

Concerns include dependency on third-party data sources and the competitive landscape from established players like Chainalysis and Elliptic. Overall, Sardine delivers a compelling, well-integrated compliance and fraud prevention suite purpose-built for the crypto economy.
