Sardine

Overview

Sardine, founded in 2020, is a fraud, compliance, and identity platform that combines device intelligence, behavioral biometrics, and verification for fintech and crypto businesses. It targets high-risk financial use cases where fraud and identity decisions are tightly coupled. See all identity verification vendors for alternatives.

What it is good at

Fusing fraud and device signals with identity and compliance is the strength: device fingerprinting, behavioral biometrics, and risk scoring sit alongside KYC and AML, giving high-risk businesses a single risk picture. For fintech and crypto fighting account-takeover and synthetic fraud, the breadth and real-time signals are a genuine differentiator. The platform also covers transaction monitoring and chargeback and ACH risk, so a fintech can use one risk engine across onboarding and ongoing activity rather than separate identity and fraud stacks.

Where it falls short

Sardine is broader than pure IDV, so a team that only needs a basic document check will be paying for a platform it does not fully use. As a younger vendor its global document coverage is less deep than dedicated verification specialists, and pricing is quote-based. For a buyer that genuinely only needs a one-time document check, the analytics-heavy platform and its commercial model are more than the use case warrants.

Best for, and who should look elsewhere

Choose Sardine when you need fraud, compliance, and identity together for fintech or crypto. For a single-purpose document check consider Stripe Identity; for pre-KYC digital-footprint signals consider SEON; for US synthetic-fraud detection consider SentiLink.

Bottom line

A strong fraud-plus-identity platform for fintech and crypto, best when risk and identity are intertwined.
