SentiLink

SentiLink builds fraud and identity products that financial institutions plug into the application stage to catch synthetic identities, ID theft, and first-party fraud before an account or loan is opened. Founded in 2017 by two early Affirm risk leaders, the company now serves 13 of the top 15 US banks, 6 of the top 10 credit unions, and over 50 fintech unicorns including Stripe, Current, and Cherry. The approach pairs ML models with a Risk Operations team that hand-reviews cases every day (the whole company spends an hour each Thursday looking at fraud together). Backed by Andreessen Horowitz, Craft, and NYCA, the team is mostly remote with regular in-person meetups and 14/10-week paid parental leave.
