Hi [first name],

zkAgent proves that every step of an agent's run stayed under a public risk ceiling without revealing the actual risk scores, using Pedersen-commitment range proofs. A step over the ceiling cannot be proven.

Hi [name], zkAgent proves an agent stayed under its risk limit without revealing the scores. Happy to show you the live demo.

One follow-up, three days later (then stop)

Hi [first name], here is the live demo: https://cainstudio.online/guide-zkagent-lab.html

Live demo call script

1. Show the normal case
   Do: Open https://cainstudio.online/guide-zkagent-lab.html and run: Risk score 0.2 (under the ceiling)
   Say: A valid proof.

2. Now the attack
   Do: Run: Risk score 0.97 (over the ceiling)
   Say: Cannot be proven.

3. 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.

4. Say the limit yourself
   Do: It proves the scores were under the ceiling; it does not prove the scores were computed correctly.
   Say: Say it before they ask. It costs nothing and it earns trust.

When they push back

Does it prove the scores are right?

No, only that they were under the ceiling.

Why should I believe your numbers?

You shouldn't have to. Run the kit on your own computer: https://cainstudio.online/ihvrk-zkagent.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-zkagent-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 CAIN zkAgent as the $500 30-day pilot.

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.
