30-second pitch

VeriCoding (Z3): VeriCoding mathematically proves a small function is correct for every possible input, or shows the exact input that breaks it.

We recorded 7 live checks, including 5 attack cases it had to refuse or flag, and every one matched. You can re-run them yourself without an account.

Subject: proving your [fee / limit] rule for every input

Hi [first name],

Tests cover the inputs someone thought of. We prove small critical functions correct for
every input, or hand you the exact input that breaks them, signed.

LinkedIn connection note (under 300 characters)

Hi [name], we prove small critical functions (fees, limits, permissions) correct for every input, or find the input that breaks them. Happy to show a 2-minute demo.

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

Hi [first name], if you name one function that keeps you up at night, I'll tell you whether we can prove it.

Live demo call script

1. Show the normal case
   Do: Open https://cainstudio.online/top25-vericoding-lab.html and run: Sample: A correct clamp (Z3 proves the contract already holds)
   Say: Z3 proves the contract or returns a concrete counterexample.

2. Now the attack
   Do: Run: Sample: A discount that can make the price negative
   Say: Z3 proves the contract or returns a concrete counterexample.

3. Now the attack
   Do: Run: Sample: max3 returns c instead of the true maximum
   Say: Z3 proves the contract or returns a concrete counterexample.

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

Our functions use lists and floats.

Then it is not ready for them; the subset is small today and we say so.

What if the contract is wrong?

Then the proof is about the wrong thing. Writing the contract is the important step; we help.

What is Z3?

A widely used mathematical solver from Microsoft Research. We did not invent it; we package it with signed results.

Why should I believe your numbers?

You shouldn't have to. Run the kit on your own computer: https://cainstudio.online/ihvrk-vericoding.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-vericoding-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 VeriCoding inside Fix + Prove, per critical function.

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.
