30-second pitch
Payment Mandate Guard makes an AI shopping agent stick to exactly what a person approved: right store, right items, right bank account, right amount. We recorded 6 live checks, including 4 attack cases it had to refuse or flag, and every one matched. You can re-run them yourself without an account. Don't trust us.

Subject: what stops your agent paying a fake store? Hi [first name], AI agents that buy things can be fooled: a look-alike store, a hidden line that adds a gift card, the right supplier with the wrong bank account. Payment Mandate Guard checks every purchase against what a person signed and refuses anything that doesn't match.

Live demo call script
1. Show the normal case Do: Open https://cainstudio.online/guide-payment-mandate-guard-lab.html and run: Control: the watch and the band the person asked for Say: Inside every limit at authorized stores: both purchases must go through, with receipts. 2. Now the attack Do: Run: Fake store: a look-alike Walmart Say: walmart-deals.shop imitates walmart.com. Modeled on a real 2025 test where an AI browser bought from a fake store. 3. Now the attack Do: Run: Right store, criminal's bank account Say: Invoice-redirect fraud: the merchant is real, the payee account is not theirs. 4. Let them check you Do: Send the kit link and ask them to run python3 verify.py --live on their own computer. Say: They don't have to take your word for any of this. That's the point. 5. Say the limit yourself Do: It authorizes; it does not move money. The payment system must ask it before paying. Say: Say it before they ask. It costs nothing and it earns trust.
When they push back
Our card has limits already.
Card limits cap the amount. They do not check the store, the items, or whose bank account gets paid.
Does it move money?
No. It tells your payment step yes, no, or ask the person.
What if the agent skips it?
Then it is not governed. Put the check in the payment path.
Why should I believe your numbers?
You shouldn't have to. Run the kit on your own computer: https://cainstudio.online/ihvrk-payment-mandate-guard.html. It re-sends every request and compares the answers, using no code of ours.
What doesn't it do?
Written down here: https://cainstudio.online/guide-payment-mandate-guard-limits.html
Are you SOC 2 or ISO certified?
No, we hold no certification. What we offer instead is evidence you can check yourself.
Has anyone independent tested it?
No third-party audit has been completed. The attack cases in the kit are our own. I'd rather tell you that now.
Who else uses it?
We are an early company. I can show you the product working and the evidence, not a customer list.
It found nothing. So we're safe?
No. It means none of its checks fired. It doesn't prove something is safe.
How much is it?
Sell Payment Mandate Guard as the $500 30-day pilot on the client's own agent.

The rules
- Send each message yourself, one person at a time. No bulk lists and no automated sending.
- Commercial email needs your real name, a real postal address and a way to opt out, and you stop when someone asks (US CAN-SPAM; many countries are stricter, so check yours).
- Never change a number, invent a customer, or say certified, audited or guaranteed.
- Only test a system the client owns or operates, after they confirm it in writing.
- Your share is agreed in writing with FIRME AI CORPORATION before your first message (email vincent@firmeai.com). Nothing here promises income. Most messages get no reply; that is normal.
