An online course can't tell you if your idea actually works.
Creators don't show their 47 failures — only the rare wins.
Most ideas die quietly because no one pressure-tested them first.
The problem isn't ideas. It's believing them too quickly.
Three patterns that show up over and over before founders ever write a line of code.

Founder · ValentProof
Built by a founder, not a content business.
Hi — I'm Martin. I built ValentProof because I've watched too many smart people waste a year on something nobody wanted.
It's the tool I wish I'd had ten years ago: a structured second opinion, not a course, not a guru, not a pep talk.

Frequently Asked Questions
How is this different from asking ChatGPT myself?
ChatGPT will tell you what you want to hear unless you know exactly how to push back. Our wizard asks the 15 questions that force the trade-offs into the open, and the report scores your idea on four independent dimensions using a fixed rubric. You get the same hard questions every time — no cherry-picked prompts, no inflation. The full rubric is public: /methodology.
What's actually in the report?
A short cleaned-up version of your idea, four scores (Idea Clarity, Commercial Potential, Validation Readiness, Evidence Confidence), the strongest and weakest parts, your key assumptions to test, the most likely failure modes, a sharper version of the idea if we see one, and concrete next steps to take this week. See a real example end-to-end at /sample-report.
What if my idea is too early or too vague?
That's fine — the wizard is designed to handle vague ideas. The report will explicitly flag what's unclear, suggest a sharper version, and tell you what to nail down before paying for a second pass.
What if I disagree with the recommendation?
The report is a structured second opinion, not a verdict. Every score includes the reasoning behind it and every warning includes evidence from your own answers. If you disagree, you have something concrete to argue against — which is usually more useful than agreement.
Is this professional advice?
No. The report is a structured second opinion produced by an AI pipeline. It's a thinking tool, not a substitute for a lawyer, accountant, or industry advisor. If the decision is big enough that you'd hire a consultant, hire one — and bring the report to the conversation.
Is this a subscription?
No. You pay once for a set number of validations. No auto-renew, no recurring charges, no surprise emails.
Do my validations expire?
Never. Buy one today, use it next month — it sits in your account until you're ready.
Do you offer refunds?
Yes — unused validations are refundable within 14 days of purchase. Once a validation has been used to generate a report, that one isn't refundable, but any others in your balance still are.
