Sentilink

Sentilink detects synthetic identity fraud and the theft of real personal data, and is based in San Francisco. It was founded in 2017 by former risk engineering leads at Affirm, and the company states that it finds fabricated SSNs and profiles.

Products The product list includes a Synthetic Fraud Score API, an ID Theft Score, first-party fraud detection and an Instant Investigation Tool. Scores are returned through the API during application or onboarding, so a lender or fintech can decide whether an applicant is a real person with a genuine history. The investigation tool lets analysts review a flagged case.

Customers The company says that ten of the top fifteen US banks are among its clients, alongside fintechs, lenders, PSPs and BNPL providers. Coverage is limited to the United States.

Contract An enterprise API contract. Since the product is built around US data such as SSNs, it is relevant mainly for American programs, and buyers outside the US should check applicability before an evaluation.
