SentiLink

SentiLink, founded in 2017 and based in the United States, helps financial institutions stop fraud at the application stage. Its platform verifies identities and detects identity theft, first-party fraud, synthetic identity fraud and emerging fraud types in real time, combining machine learning models with insights from a dedicated group of risk analysts. The approach places human analysts who understand how fraudsters operate alongside automated systems, a blend the company describes as human-in-the-loop risk modelling.

The company has verified hundreds of millions of identities across the financial services landscape. Its customers include the largest U.S. banks, credit unions and fintech unicorns, spanning the banking, credit union and fintech verticals. SentiLink has been named on the Forbes Fintech 50 list multiple times and is backed by investors, though the amount and stage of funding are unspecified.

Technical work at SentiLink spans machine learning, identity verification, fraud detection, synthetic identity fraud detection, real-time fraud prevention and risk analysis. The company frames its mission as protecting people and institutions from sophisticated fraud attempts, and describes a team that takes the impact of its work seriously.
