Summary
👤
Senior🎓
Top SchoolNaftali Harris is a founder and data-driven CEO with 13 years of experience building fraud and decisioning systems that scale for financial services. As Co-Founder and CEO of SentiLink since 2017, he leads a company trusted by hundreds of institutions to stop fraud and streamline onboarding, applying product-focused machine learning to high-stakes risk problems. His prior roles at Affirm — from first data scientist to data science manager — include shipping the company’s initial fraud model (reducing fraud losses 10x) and leading an eight-person team whose models unlocked major financing and saved tens of millions annually. Trained in statistics at the University of Chicago and Stanford, he combines rigorous quantitative foundations with hands-on model deployment and operational risk practices. Less obvious: he learned early-career at scale (Twitter, Kaggle) how to squeeze performance from models and infrastructure, a habit that shows in SentiLink’s production-first posture.
