Ad spend cards, cash-gap funding, and agent audit via MCP
Give your AI agent financial rails for paid ads. Issue virtual cards with custom spend caps, fund cash gaps so winning campaigns keep scaling while revenue catches up, and let your agent check charges against live ad results via MCP. Built for businesses that scale on paid ads.
We first launched here with a simple ad spend tool, before we had cards. The interest in our MCP helped shape what came next. From buying media ourselves, we already knew how disconnected the money side of paid ads was.
Today we're back with headless finance: cards and capital in your AI workflow.
You can use it through Claude, IDEs like Cursor, coding agents in the CLI like Claude Code and Codex, or our ChatGPT app.
If you're scaling paid ads, checking campaign performance is only part of the job. You also need to know what actually hit the card, how much spending room is left, and whether you can keep funding campaigns while revenue catches up.
For SaaS/Enterprise/AI teams, that can mean paying upfront to acquire customers whose subscriptions pay back over time.
For service businesses, it can mean funding ads while waiting for customers to pay.
Our existing MCP brings ad performance and revenue into the conversation. This release adds the cards behind that spend.
You can compare card charges with campaign results, check spending room, then issue a card to an existing cardholder, change its spend cap, or freeze and unfreeze it. Card changes are limited to owners and admins, with your confirmation before every change. We aimed for less "here's a report." More "let's sort it out here."
Flyweel also offers funding to bridge the gap between ad spend and revenue collection. Cards are for US businesses; capital is subject to eligibility and approval.
One thing we'd like your input on before we build it:
Should we add the ability to launch and control ad campaigns through MCP too? We're considering including this at no extra cost for card users. Campaign controls aren't available today; our ad-platform connections are read-only.
Would you use that?
I'll be in the comments. Happy to talk through how it works and where the limits are.
