Score your idea on the weights we actually use
7 areas, each rated 0-10, each multiplied by a fixed weight and added up in code — arithmetic, not an opinion. Sales & Trust Fit carries 20 of the 100 points and Cash-Flow Sustainability + Transferability carries 5 — a rating point of the first moves your total 4× as far. Drag them and watch which one actually moves it.
Can the buyer be reached with async marketing? How much trust is required to convert?
Is there a repeatable, low-cost channel the founder can operate (SEO, IH, X, niche newsletters, etc.)?
Plausible price point, margin after AI costs, gross margin sustainability for a solo operator.
Strength of the evidence from the Pain Box + demand-proof signals. Public sources or pasted evidence beats assumption.
Support burden, onboarding friction, manual work per user. Solo founders cannot scale white-glove ops.
Platform-dependency risk, AI dependency, legal/regulatory exposure, ToS risk.
Months to break-even on hosting + AI costs. Transferable asset value (can the asset be sold?).

What this is, and what it is not
- The weights and the arithmetic are the real ones. This page imports them from the modules the product scores with, so it cannot show you a rubric the engine does not apply. Grades: A 80+ · B 65–79 · C 50–64 · D under 50.
- The ratings here are yours. In a real run a model rates each area against sourced evidence, and those ratings move between runs — same idea, same input, a different read. The arithmetic on top of them does not move. That is the honest division of labour, and it is why this tool is a way to see the rubric, not a verdict on your idea.
- Nothing here predicts whether the business works. A high number means your own ratings were high. The value is in which area cost you the most points, and that is a question about where to look next.
- A real report carries one more category. Founder Understanding Fit is scored but deliberately kept out of the weighted total — it gates the idea instead of shading its number. That is why there are 7 sliders here and more rows on a report.
The reasoning behind each weight is in how to score a business idea, and how it works covers where the ratings come from in a real run.
The hard part is the ratings, not the total
You just supplied 7 numbers about your own idea. A real check does not take your word for them: it runs 12 deal-breaker checks, any one of which can end the idea on its own, and labels what it could not verify instead of rating it anyway. See a real report.
