SentiLink provides innovative identity and risk solutions, empowering institutions and individuals to transaction with confidence. We’re building the future of identity verification in the United States replacing a clunky, ineffective, and expensive status quo with solutions that are 10x faster, smarter, and more accurate.
We’ve seen tremendous traction and are growing extremely quickly. Our real-time APIs have helped verify hundreds of millions of identities, starting with financial services and rapidly expanding into new markets. SentiLink is backed by world-class investors including Craft Ventures, Andreessen Horowitz, NYCA, and Max Levchin.

Affordable Benefits — Healthcare is described as employer‑paid for medical, dental, and vision—often extending to dependents—reducing employee premium burden. Third‑party summaries also reference “fully covered” plans, indicating low out‑of‑pocket costs when accurate.
-
Parental & Family Support — Parental leave is advertised as fully paid (e.g., 14 weeks for birthing parents and 10 weeks for non‑birthing parents), alongside family medical leave and fertility benefits. This signals meaningful support for growing families.
-
Leave & Time Off Breadth — Time off is framed as generous, including PTO, paid holidays, paid sick days, and bereavement leave, with some roles noting flexible or unlimited PTO. Such breadth covers common personal and wellness needs.

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.
