## Overview

Sardine, founded in 2020, is a fraud, compliance, and [identity](https://startwithidentity.com/guides/compliance/customer-identity-verification-guide/) 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](https://startwithidentity.com/vendors/identity-verification/) 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.

## Pricing

Usage-based and quote-based. Model your real volume with the [TCO calculator](https://startwithidentity.com/tools/tco-calculator/).

## 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](https://startwithidentity.com/vendors/identity-verification/stripe-identity/); for pre-KYC digital-footprint signals consider [SEON](https://startwithidentity.com/vendors/identity-verification/seon/); for US synthetic-fraud detection consider [SentiLink](https://startwithidentity.com/vendors/identity-verification/sentilink/).

## Bottom line

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