The Curious Phenomenon of Synthetic Fraud with SentiLink

The Curious Phenomenon of Synthetic Fraud with SentiLink

Naftali Harris is the Co-Founder and CEO of SentiLink, a synthetic fraud prevention company.

Naftali was the first data science hire at Affirm, where he built some of the lender’s first fraud models.

For the past couple years, Naftali has been working to solve the problem of synthetic fraud, a surprisingly pervasive and little-discussed source of credit losses for banks.

Earlier this year, SentiLink raised a $14 million Series A round led by Andreessen Horowitz, in which Affirm's Max Levchin, and Plaid CEO Zach Perret also participated.

In addition to the insights we deliver through our podcast and newsletter, Rebank offers advisory services to fintechs, banks and corporates.
