SentiLink helps institutions and protects customers by accurately resolving identities and flagging fraud risk. Each day, we verify more than 3 million identities, flagging 150k+ fraud attempts in the process. The problems we work on are challenging, and solving them takes deep domain expertise, rigorous analysis, and a willingness to dig into the details.
At SentiLink, you'll work alongside smart, highly collaborative colleagues who respect each other's time and judgment, take ownership, and follow through on their commitments. Together, we do truly meaningful work protecting the identities of innocent consumers and flagging the fraudsters attempting to exploit them.
We're well capitalized and growing quickly. We already serve 13 of the top 15 U.S. banks, we're expanding into new markets, and we're backed by Craft Ventures, Andreessen Horowitz, NYCA, and Max Levchin. We've been named to the Forbes Fintech 50 and as a 2026 FICO Industry Vanguard Decision Award Winner. We were also the first company to go live with the electronic Consent Based Social Security Number Verification (eCBSV) service, and we've testified before the U.S. Congress on the future of identity.

SentiLink Insights
What We Do
SentiLink is the leading fraud intelligence company, providing financial institutions and fintechs with purpose-built solutions for identity verification and fraud prevention. Our products detect synthetic fraud, identity theft, and hard-to-detect first-party fraud in real time — helping partners stop losses before they happen while approving more legitimate customers. Founded in 2017 by Naftali Harris and Max Blumenfeld, creators of the risk and fraud systems at Affirm, SentiLink was built on a simple premise: to truly stop fraud, you have to deeply understand it. That belief shapes everything, from the expert human intelligence that feeds our models to the way we work with our partners. We don't call them clients or customers, we call them partners, because that's genuinely how we think of them. Today, SentiLink processes 3M+ identity verifications per day for 500+ financial institutions, including 13 of the top 15 U.S. banks and 50+ fintech unicorns. We've raised $85M from investors including Andreessen Horowitz, Craft Ventures, and NYCA Partners.
Why Work With Us
At SentiLink, deep understanding isn't just a value, it's a company-wide expectation. For example, our Revenue Accounting Manager can walk you through SSN windows. That's not an exception; that's the norm. You'll collaborate closely, move fast, and do work that genuinely matters.
