Allowance creates scoped payment credentials for AI agents, letting them make purchases on a user's behalf without exposing real card numbers. The platform generates one-time virtual cards with customizable controls including spending limits, merchant restrictions, and expiration windows. This lets AI agents safely complete tasks like shopping, ordering food, booking reservations, or buying tickets. Allowance is part of Y Combinator's Spring 2026 batch and was founded by Dasmer Singh, previously Head of Product for Cash App Families.
