Real-Time Underwriting Risk and Fraud Analytics for an Embedded Patient-Financing Provider


Let's Connect

Problem

Slow approvals, rising losses

A patient-financing fintech embedded in roughly 60 dental offices approved treatment plans at the front desk using a manual rules checklist. Decisions took several minutes while patients waited, borderline applications defaulted to rejection, and identity fraud was slipping through unnoticed. Delinquency at 90 days had climbed above 9%, squeezing margins on every funded plan.

Solution

Real-time risk scoring engine

We built a real-time underwriting engine combining a gradient-boosted repayment-risk model trained on historical plan performance with a parallel fraud layer scoring device, identity and velocity signals. A decisioning API returns approve, decline or refer in under 20 seconds, borderline cases route to a human review queue, and drift and portfolio dashboards keep both models continuously monitored.

Measurable Impact

What changed after launch

Median point-of-sale decision time cut from over 4 minutes to under 20 seconds

90-day delinquency reduced from 9.1% to 6.4% at an unchanged overall approval rate

Confirmed identity-fraud losses down 38% across the first two quarters after launch

Manual underwriting reviews narrowed to 7% of applications via the referral queue
