What comes back

The free verdict, exactly as it arrives.

Killer Score

42

/ 100

Confidence: Low

You named the product but not the buyer or the price, so claim-dependent dimensions are capped instead of inflated.

The good

The workflow you described is genuinely repeated and currently manual.

The problem

“Small businesses” is a market, not a buyer. Nobody has a budget line for mild friction.

Prove this

Ten exact-buyer conversations and one costly commitment before you write code.

What we’re assuming

That the buyer pays for tools today, and that the trigger is weekly.

Still unknown

Whether anyone has ever paid to solve this, and who signs.

Why this matters

You do not need more encouragement. You need a cleaner next move.

Compliments are weak evidence
Friends and family are not your buyer.
Broad buyers create weak positioning
Narrow until one person clearly signs.
Conviction should follow signal
The market is brutal and slow. This is brutal and fast.

What Killer Idea tests

Six dimensions. One hundred points. No mystery math.

  • Pain22 ptsIs the problem expensive, repeated, and already being worked around?
  • Willingness to Pay22 ptsIs there a budget owner and a believable price?
  • Differentiation16 ptsIs there a substantive reason to switch?
  • Reach13 ptsIs the specific buyer reachable through a plausible first channel?
  • Execution12 ptsCan the core hypothesis be tested and a focused wedge delivered?
  • Evidence15 ptsHow much useful buyer, pricing, commitment, channel, alternatives, and concept context was supplied?

Weak evidence caps claim-dependent dimensions. The breakdown always sums to the headline score.

Find the weak spot

Get the score, the confidence level, and the specific assumptions that make the idea fragile.

Sharpen the wedge

Turn the broad idea into a narrower buyer, sharper pain, and a first testable offer.

Decide what to test

Use the next-signal read and kill criteria to avoid mistaking enthusiasm for demand.

Use Killer Idea when

You are about to build, hire, pitch, spend, or convince yourself that vague interest means real demand.

Do not use it when

You only want validation theater, legal advice, investment advice, or someone to tell you the idea is definitely brilliant.

The expensive part is not the verdict

Most founder failures are conviction failures: building too long on a vague buyer, soft pain, fake urgency, or a product nobody asked for.

FAQ

Real objections, short answers.

Should I validate before building?

Yes. Validation is cheaper than a six-month build defending a weak assumption.

Can ChatGPT validate my startup idea?

A chat can brainstorm. It has no fixed scoring framework, no evidence constraints, and no kill criteria.

What does the free verdict include?

A Killer Score with a full point breakdown, a confidence level, the good, the problem, what to prove next, plus labeled assumptions and unknowns.

Do I need an account?

No. The first verdict is free and requires no signup.

Is my idea private?

Yes, by default. Nothing is published unless you publish it.
