The challenge

Fraud on online loan applications was being caught too late — after approval or funding. The lender needed to stop it before money moved, without blocking genuine customers.

How it works

Every application gets a 0 to 1 risk score and an explanation.

Low riskFast-tracked, with a sampled audit
Medium riskA reviewer decides
High riskCompliance verifies first
Decision loggedEvery decision becomes a label the models learn from

Under the hood: about 100 raw fields expanded to 650+ behavioural signals, a supervised model and an anomaly detector. Drift is monitored, and a retrained model is promoted only if it beats the previous one. Nobody is auto-declined.

What it is worth

Industry research (LexisNexis True Cost of Fraud, 2025) puts the total cost to US lenders at $5.38 for every $1 of fraud lost. Per $1M of direct fraud loss at the 48% baseline:

$5.38Mtrue cost before AI
$0.34Mwith AI scoring
$5.04Mtrue cost avoided

Client-reported results on 394 online applications, shown without the customer name. The multiplier is a US figure; we validate it for your market.
