About Allowance
Summary
Allowance builds a payment control layer for AI agents, letting them complete purchases on a user's behalf without exposing a real card number. For each transaction, the agent proposes a purchase and the user approves it from their iPhone, setting constraints such as spending limits, merchant restrictions, and expiration windows. Allowance then generates a scoped, single-use payment credential tied to that specific transaction, replacing the need to hand an AI agent open-ended access to payment credentials.
Business model
Omitted: sources do not specify how Allowance charges customers.
Go-to-market
Consumer shoppers adopt the product through a self-serve mobile flow, approving individual AI-initiated purchases directly from an iPhone app.

The spend control layer for AI agents
Allowance lets AI agents make purchases on a user’s behalf without ever exposing your real card number. Users approve purchases directly from their iPhone with customizable controls like spending limits, merchant restrictions, and expiration windows. Once approved, Allowance generates scoped, one-time payment credentials designed specifically for that transaction. This enables AI agents to safely complete tasks like shopping, ordering food, booking reservations, or purchasing tickets while keeping humans in control of every payment.
