Who to approach

Buyer's security engineer: Is the vendor's claim real?
Auditor or technical advisor to an investor: Evidence that stands on its own.
Your own prospect's CTO: Will my customers believe the evidence I give them?

Questions to ask them

How do you normally check a vendor's security claims?
Who on your team would run a checker if we sent one?
Do your customers ask you for evidence you then have to pass on?
Do you prefer to verify offline?

30-second pitch

Offline verifiers (NULLIUS): NULLIUS lets anyone check our evidence on their own computer with tools that contain none of our code: the reason a sceptic can believe us.

We recorded 5 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.

First email

Subject: check our evidence without trusting us

Hi [first name],

You asked how you can know our results are real. You don't have to take our word:
this checker contains none of our code, is short enough to read, and runs offline against our published
evidence and key: https://cainstudio.online/top25-offline-verifiers-verify.html

If anything does not verify, tell me and I'll get you an answer from our engineers.

The evidence: We recorded 5 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.

LinkedIn connection note (under 300 characters)

Hi [name], we publish checkers that let anyone verify our security evidence offline, without our code. If you review vendor claims, I'd value your opinion.

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

Hi [first name], did your engineer get a chance to run the checker? Happy to walk through it for ten minutes.

Live demo call script

1. Show the normal case
   Do: Open https://cainstudio.online/top25-offline-verifiers-lab.html and run: KEYSTONE ledger chain re-verifies
   Say: The whole hash chain, live.

2. Now the attack
   Do: Run: Ledger: latest record with its verdict edited to NOT_VERIFIED
   Say: Changing any signed field breaks the record hash and signature.

3. Now the attack
   Do: Run: Receipt with decision flipped to ALLOW on a DENY
   Say: The signature covers the decision.

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: Tell them what the kit does not show.
   Say: Say it before they ask. It costs nothing and it earns trust.

When they push back

You wrote the checkers too.

True, and we say so. They are short so that you can read them, and no third party has reproduced them yet.

45 edits were accepted?

Yes: fields documented in advance as not covered by the signature, such as display notes. None changed a verdict.

Are all your products covered?

No. Three of 18 checkers are published today. We show which evidence they cover.

Why should I believe your numbers?

You shouldn't have to. Run the kit on your own computer: https://cainstudio.online/ihvrk-offline-verifiers.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/top25-offline-verifiers-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?

NULLIUS is free. Use it to remove doubt, then sell the offer the prospect actually needs (often the Safety Evidence Pack).

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.
