How this free startup idea validation tool works
Three steps, and no generic questionnaire: every question is tailored to your idea.
- 01
Describe the problem and your solution
Two short fields. Who has the problem, in what situation, what it costs them today, and what you propose instead. One real situation beats a general statement.
- 02
Answer a few targeted questions
The AI reads your idea and writes 3 to 5 questions about what it leaves uncertain. Each one asks about something that already happened: the last time, the exact figure, the person you spoke to. Never "would you pay for this?".
- 03
Get your scored verdict
About a minute later: a score out of 100, your five dimensions on a radar, a written verdict and the assumption to test first. Each report is saved to your history, so you can edit the idea and run it again.
What your validation report tells you
No 20-page document. One screen you can act on: where your idea is strong, where it is fragile, and what to check first.
A verdict you can act on
The score shows where your idea stands. The verdict explains why in a few plain sentences, and the riskiest assumption tells you what to test before anything else.
- A score out of 100 with a clear badge: Promising lead, Worth digging or Weak signal
- A written verdict that weighs strengths and weaknesses, without filler
- Your riskiest assumption: if it is wrong, the idea does not hold
- Signals flagged favourable, neutral or to watch, such as field evidence, retention or competition
The five dimensions, each rated out of 5
Notes are built from your answers. The three market dimensions also draw on the AI's general knowledge and are flagged as estimates, so you know what to check in the field. A dimension that cannot be supported is marked "not assessed" rather than guessed.
- 01
Problem severity
How badly the problem hurts, judged on real occasions rather than opinions.
- 02
Founder fit
What you have personally done in this field, or who you can count on who has.
- 03
Market size
Who exactly has the problem, and how many of them there are.
- 04
Market dynamics
What has changed recently that makes the idea possible or necessary now.
- 05
Competitive intensity
What people already use instead, and how crowded the ground is.
How to read your score
- Promising lead80–100
Signals are good across most dimensions. Move on to a test with real stakes.
- Worth digging50–79
The idea holds up, but several points need genuine verification.
- Weak signal0–49
The foundations are fragile. Rework the idea before investing more time.
Built on methods founders already trust
The questions and the score are not improvised. They apply four well-known startup validation methods, so the verdict rests on evidence rather than enthusiasm.
- 01
Ask about the past, not the future
Inspired by The Mom Test by Rob Fitzpatrick. "Would you pay for this?" gets a polite yes. "What did you pay the last time?" gets a number. Every question follows that rule.
- 02
The questions YC asks about ideas
The five dimensions are inspired by the questions Y Combinator partner Jared Friedman uses to evaluate startup ideas: how much the problem hurts, why you, how big, why now, and who is already there.
- 03
Not all evidence is equal
Following Alberto Savoia's scale, a friend's opinion counts for less than an email left on a waiting list, which counts for less than a deposit paid. With opinions alone, the problem-severity note cannot go above 3 out of 5.
- 04
What makes customers switch
Following Bob Moesta's four forces, the questions look at what worries your customers about changing and what keeps them attached to their current solution: two often-overlooked reasons "good" ideas fail.
No score is ever made up
If fewer than four dimensions can be assessed, you get no score at all, just an explanation of what is missing. A missing dimension is never counted as zero, and the radar shows it as a dashed axis rather than a dent.
Frequently asked questions
A score out of 100 with a badge (Promising lead, Worth digging or Weak signal) and a note out of 5 on five dimensions, shown on a radar chart: problem severity, founder fit, market size, market dynamics and competitive intensity. You also get a written verdict, your riskiest assumption and a row of signals flagged favourable, neutral or to watch.
Because a description says what you hope, not what you know. The 3 to 5 questions are tailored to your idea and ask about concrete past facts, following The Mom Test: the last time the problem came up, what people pay today, who you actually spoke to. The more concrete your answers, the more reliable the verdict.
Each of the five dimensions gets a note from 1 to 5, and the score is their total converted to 100. A dimension that cannot be assessed is left out rather than counted as zero, and below four assessed dimensions no score is shown at all. From 80 your idea is a promising lead, from 50 it is worth digging, below that the signal is weak.
It is as solid as your evidence. Opinions alone cap the problem-severity note at 3 out of 5, while a real commitment such as a deposit can earn the full range. Market notes rely on your answers and the AI's general knowledge, and the report flags them as estimates so you know what to verify in the field.
Then start one step earlier. The startup idea generator works from your skills, your past roles and the problems you have seen go unsolved, and offers you a shortlist of ideas assessed in the same way. Come back here once you have made your choice.
The Lean Canvas generator structures your idea into a one-page business model. The idea validator comes one step earlier: it tests whether the problem is real and painful, whether you are the right person to solve it, and how the market and competition look, before you commit to building.
Your idea and answers are sent to OpenAI to generate the analysis. Each report is saved to your SeedAngels account, so you can reopen it, edit the idea and run it again, or delete it whenever you want. No human reads your analyses.
