The offer, the price and the close
Sell VibeGuard inside the Fabrication Audit for AI-written codebases, plus Fix + Prove for findings.
What you sell
Fabrication Audit
Finds code that looks finished but is not, with a signed report the client re-checks.
$1,500 standard · $3,500 deep · $6,000 diligence (for an investor or acquirer)
Turnaround: 48 hours for the standard tier; larger scopes agreed in writing · Payment: 50% up front
What the client receives
- report.md: every module graded REAL / PARTIAL / STUB / UNKNOWN, with the exact lines that caused each grade.
- findings.json: the same result for the client's engineers, machine readable.
- evidence.zip: a signed record plus a small checker that imports none of our code.
- A list of the files that were clean, and a section of notes from the person who reviewed it.
What the offer itself says about its limits
- The detector is precise but narrow: it misses many kinds of fake code. A clean grade is not a guarantee.
- A person reviews every finding before the report goes out.
Price source: Operator playbook stream 1 (docs/strategy/CAIN-AS-A-BUSINESS-OPERATOR-PLAYBOOK.md); delivered by cain_audit. Prices are the founder's proposed list prices, not validated market rates; any discount needs the founder's OK.
Also offer
Fix + Prove
We ship the patch and prove it: the test fails on the old code and passes on the new.
$500 small fix · $1,500 standard · $2,500 complex fix
Turnaround: 1–2 weeks · Payment: 50% up front
What the client receives
- The patch, applied on a branch.
- An independent test that fails on the old code and passes on the new.
- A signed, hash-chained record and a standalone verifier.
- A short note the buyer can forward to their own customer.
What the offer itself says about its limits
- A proof covers the contract and the tests we ran; it is not a proof that the whole system is safe.
- If the independent test cannot run, the verdict is NOT_VERIFIED and nothing is issued.
- We do not claim a fix we did not prove.

Subject: checking the code your AI wrote
Hi [first name], AI-written Python has typical mistakes: invented packages, swallowed errors, fake scores. We catch them with rules and only sign a repair that adds nothing new. https://cainstudio.online/top25-vibeguard-lab.html [your name], FIRME AI CORPORATION
LinkedIn connection note (under 300 characters)
Hi [name], we check AI-written Python for the typical mistakes (invented packages, swallowed errors) before launch. Happy to show you.
Follow-up, three days later
Hi [first name], before launch is the cheapest time to catch these. Want a fixed-price check?
