# Small-business credit underwriting

> Real-time underwriting from bank-transaction data, not pulled credit reports.

**Sector**: [Fintech](https://signals.gitdealflow.com/niche-down/fintech)  
**Build cost**: Team-sized build  
**Deal velocity**: Steady — one deal per month

## Why now

Banks still pull 3-year credit reports for $50k loans. AI lets you underwrite from 90 days of bank transactions and get a more accurate signal.

## What the signal looks like

Repos with Plaid / Codat / Rutter integrations, cash-flow ML models, and risk-grading libraries.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- Pipe-style revenue-based financing
- Clearco shape
- Plaid-powered underwriting infra

## What this displaces

A bank's commercial lending team and a PDF tax return upload.

## Our build-vs-invest call

Capital-heavy. Fund only if there's a lending partner already lined up. The infra (data + model + decisioning) is the product to build; the lending itself is the partnership.

## Frequently asked

### Aren't we late?

The first wave struggled with capital costs. The infra-layer (sell to lenders) is the second wave.

### Who buys the infra?

Mid-tier banks + fintech lenders.

### Defensibility?

Model accuracy on the long tail. The big banks won't underwrite a one-person business; you can.
