Allowance issues one-time virtual cards

Allowance, a San Francisco startup founded in 2026, is pitching one-time virtual cards as a way for AI agents to make purchases without exposing a user’s primary card number. Y Combinator’s company page says the product lets users approve purchases from an iPhone and set controls including spending limits, merchant restrictions and expiration windows before a credential is issued. The company says the cards are designed for tasks such as shopping, food orders, reservations and ticket purchases. Y Combinator’s launch page for the company said Allowance had been used for “food orders, reservations, and ecommerce checkouts” with one-time virtual cards and approval controls. A Y Combinator social post on Saturday described the product as built for travel booking, price tracking, reservations and e-commerce. ### How does the product work at checkout? Allowance’s website says users give an AI agent “a controlled spending limit — not your credit card.” The site says customers can set a budget, merchant rules and time limits, then use the service with ChatGPT, Claude and OpenClaw. (ycombinator.com) Y Combinator’s company profile says the approval flow starts with a purchase request on an iPhone. After the user approves it, Allowance generates scoped, one-time payment credentials for that transaction, rather than sharing the underlying card number with the agent. (ycombinator.com) ### What guardrails does Allowance say it enforces? Y Combinator said the controls include spending limits, merchant restrictions and expiration windows. (useallowance.com) Those settings are meant to narrow where, how much and for how long a payment credential can be used. The company’s public materials frame those controls as part of a broader push to make agent-driven payments auditable and bounded. While Allowance does not list a full policy manual on its homepage, its product language centers on one-time credentials and user approval before payment.

Ramp said in an April 28 blog post that autonomous software increasingly needs a way to pay vendors, renew software and order goods, and that programmable virtual cards can give agents transaction-specific credentials with spend limits and expiration windows. (ycombinator.com) Ramp said those controls are aimed at finance teams that want auditability and revocation. Other startups are making similar pitches. (ycombinator.com) AgentCard and CreditClaw have both launched products that offer one-time or prepaid virtual cards for AI agents, with controls around limits, categories, approvals and transaction visibility, according to their public product pages. ### Who is behind Allowance? Y Combinator’s profile lists Dasmer Singh as founder. The profile says Singh previously worked on Cash App Families and earlier held roles at Uber, Petal and Venmo. (ramp.com) The same profile says Allowance has one employee and is based in San Francisco. Y Combinator describes the company as building “scoped payment credentials for AI agents.” (creditclaw.com) ### Where can users find the product now? Allowance’s Y Combinator company page links to the startup’s website, and the launch page asks users to try the product and share feedback. The public homepage says the service is available through useallowance.com. (ycombinator.com)
