Janus

beta

A fused risk + growth credit agent for consumer banking: it grows revenue when a customer is safe and protects the moment risk rises — one brain, priced to risk, defended by design.

Janus — strictly-private AWS architecture — Strictly-private on AWS: CloudFront + Cognito are the only public surface; a deterministic model scores, a human approves.

what it is

Janus answers a bank's two questions about a customer — are they becoming a risk, and what should we offer next — with one brain. A deterministic gradient-boosted model scores the probability of default (the LLM never scores), a Risk and a Growth agent negotiate a priced offer inside a hard affordability envelope, and a human always approves. As an AI agent touching credit data it's defended by design: prompt-injection attacks are blocked and standards-mapped (MITRE ATLAS / OWASP), and it runs on a strictly-private AWS stack with no public endpoint. Built for AABW 2026, Shinhan Future's Lab.
