FinGuard:
AI Loan Eligibility & Risk Assessment

An ML-powered credit risk platform using alternative data sources — cash flow, rent history, employment signals — to expand lending access for the 45 million Americans who are credit invisible, without increasing lender default rates.

The Problem

45 million Americans are "credit invisible" — no credit score, or a score too thin to qualify for traditional loans. This isn't because they're high-risk. It's because the data the system uses doesn't capture their actual financial behavior. Legacy credit models look backward at credit utilization and account age, missing the signal available in how people actually manage money today.

The Tension

Lenders want to grow loan books but can't increase default risk. Traditional models have optimized as far as they can. Alternative data — available right now via Open Banking APIs — contains better predictive signals. But nobody has built a clean, compliant, explainable product to expose it to lenders.

Core Thesis

Credit risk is better predicted by behavioral patterns, cash flow, and alternative data signals than by backward-looking credit scores. FinGuard exposes these signals in a compliant, explainable, API-first product.

User Personas

Marcus — The Credit-Invisible Applicant
28 · Software Engineer · $85K salary · Recent immigrant

3 years of on-time rent, healthy cash flows, no US credit history. FICO: N/A. Banks auto-reject. Dealership offers 22% APR.

"I earn good money and pay everything on time. Why won't anyone lend to me?"

Sarah — Underwriting Manager
42 · VP of Lending · Regional Credit Union

Board wants default rates <2% but also wants loan volume growth. No in-house data science team. Current model leaving creditworthy applicants untouched.

"I know some of the people we reject would pay us back perfectly. I just can't prove it."

Alternative Data Sources — The Core Differentiator

Traditional models use: payment history, credit utilization, account age, credit mix, new inquiries. FinGuard uses all of that plus:

Why Explainability Ranks #1

Every decision must produce a human-readable explanation: top 3 positive factors, top 3 negative factors, what would change the decision, and an FCRA-compliant adverse action notice. This isn't a nice-to-have — it's legally required, and the #1 reason lenders can trust the system.

Compliance Architecture

Fair Lending — Non-Negotiable

Regular disparate impact testing across protected characteristics. Fairness constraints baked into model training. Third-party bias audit before launch. This is the most important technical requirement in the PRD.

  • FCRA: Adverse action notice generation; user right to dispute every decision
  • ECOA: No protected class data used; equal credit opportunity monitoring
  • SOC 2 Type II: Full audit trail for all data access and decisions
