Business idea validator
Ten questions, a 0 to 100 score, and specific homework for whatever is weakest. No AI opinion involved: this is the checklist experienced founders run, encoded.
Updated August 2026
Answer honestly. The score only means something if the answers describe evidence you actually have, not evidence you are confident you would find.
1. Have you seen strangers complain about this problem in public?
Reddit threads, reviews, forum posts. Friends don't count.
2. Does the same complaint show up in three or more separate places?
Different threads, different sites, different people.
3. Do competitors already exist?
Competitors are good news: they prove people pay.
4. Have people tried the existing options and complained about them?
One-star and three-star reviews are the evidence.
5. Can you name what the problem costs today?
Money spent, or hours lost, per week or month.
6. Do the people with this problem already pay for tools or services?
People who pay for adjacent things pay for new things.
7. Can you state the problem in one specific sentence?
"Salons lose $200 per no-show" beats "scheduling is broken."
8. Has anyone said "I'd pay for this" without you prompting them?
Unprompted is the key word.
9. Do you know exactly where these people gather?
Specific subreddits, groups, or communities you could post in today.
10. Has anyone paid, preordered, or put down a deposit?
The strongest signal there is.
Why a checklist beats an AI's opinion
Paste any idea into a chatbot and it will find upside, because language models are agreeable by design and have no stake in your three months. An idea validator built on AI is a compliment machine with extra steps.
What predicts whether an idea survives contact with the market is boring and countable: does the complaint repeat, do incumbents frustrate their users, can you name the cost, has anyone signaled they would pay. Those are the ten questions above, weighted by how strongly each one predicts.
The score is deterministic. Same answers, same score, no mood, no flattery.
What to do with your score
Above 75: stop researching and ask someone for money, a preorder or a founding price. That is the only signal stronger than anything on this list.
Between 25 and 75: the result page names your weakest areas. Each is usually an evening of work, searching communities, reading reviews, or messaging people who complained in public. The no-code validation guide walks every step.
Below 25: the useful conclusion is to start from different raw material. IdeaPanda exists for exactly this case: 300+ ideas that already pass the evidence questions, scored and sourced, for $24 once.
See the ideas, not just the theory.
IdeaPanda scores real business ideas on live demand, competition, and market signals, then hands you the full report behind each one. One time payment, no subscription.

Frequently asked questions
How does this idea validator work?
Ten questions cover the signals that predict market demand: repeated public complaints, existing competitors with frustrated users, a nameable cost, an audience that already pays, and willingness-to-pay signals. Each answer contributes a weighted amount to a 0 to 100 score. No AI is involved; the scoring is a fixed, transparent rule set.
Is a high score a guarantee the idea will work?
No. It means the demand-side evidence is strong, which is the part most failed projects skipped. Execution, distribution, and timing are still yours. A low score is more reliable in the other direction: building against it usually ends in silence.
Why doesn't it use AI?
Because validation is a question of evidence, not opinion. Language models are agreeable and unaccountable, which is the opposite of what you want from a validator. A fixed checklist can be argued with, which is the point.
What if I don't have an idea yet?
Then validate nothing and start from demand instead: the free idea generator deals complaint-shaped starting points, and IdeaPanda ($24 one time) is the full library where each idea already carries its demand evidence.
