# Programmable card issuing

> Stripe Issuing but vertical — virtual cards with workflow-aware controls.

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

## Why now

Vertical SaaS platforms want to issue cards branded to their flow. Stripe Issuing covers basics; vertical controls are the wedge.

## What the signal looks like

Repos with card-program APIs, fraud-rule engines, and ledger libraries.

## Public examples

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

- Lithic / Marqeta-style issuing
- Vertical card programs (trucking, hospitality)
- Stripe Issuing integrations

## What this displaces

A corporate card from Brex + a manual reconciliation flow.

## Our build-vs-invest call

Capital-heavy + regulatory. Fund only with prior issuing or banking-as-a-service team. The wedge is workflow rules — 'this card only works at gas stations in this state on Tuesdays.' Watch repos with deep MCC / fraud-rule libraries.

## Frequently asked

### Isn't Stripe Issuing this?

Stripe ships the rails. Vertical workflow controls are downstream.

### Margin?

Interchange share + monthly platform fee.

### Who's the buyer?

Vertical B2B SaaS platforms with spend embedded in their flow.
