Rate My Idea

Updated July 26, 2026 · Data snapshot July 2026

What is idea validation?

The reason validation matters is that enthusiasm is not evidence. Friends encourage you, models agree with you, and a landing page with 40 email signups tells you almost nothing about willingness to pay. What moves the odds is checking whether the problem already generates complaints, whether existing tools already fail at it, and whether anyone in that category earns money.

The base rate nobody publishes

We show researched startup ideas to founders one at a time and record whether they would pursue each one. The result is the most useful calibration number we have, and it is humbling.

Source: BigIdeasDB idea-reaction data, 1,100+ cards and 21,000+ recorded judgements (July 2026).

Two conclusions follow. First, if your idea gets a lukewarm reaction, that is the norm, not a verdict. Second, and more important: founder enthusiasm is not the signal you want anyway. The 6% with broad appeal are usually the most crowded spaces. What you want is a narrow group who feel the pain acutely, which is why this tool scores documented complaints rather than counting votes.

How this idea validation tool scores your idea

Paste your idea and get a score in seconds. The tool rates five factors, but the one that matters is demand, because it is measured against problems people already complained about rather than inferred by a model.

• Market demand: how often and how severely people complain about this problem.
• Competition: how many solutions exist and how well they are rated.
• Monetization: whether the audience already pays for something adjacent.
• Feasibility: how realistic a first version is without a team.
• Your edge: the skills, access or domain knowledge you bring.

Sample output: paste something like "a scheduling tool for house-cleaning businesses" and you get a demand score, a competition read, a monetization signal, a feasibility estimate, a plain-English verdict, and the real complaints behind the score so you can read the evidence yourself rather than trusting the number.

How to test a business idea before building it

A score is a filter, not proof. Once an idea clears the filter, run these four steps in order. Each one is cheap and each one can kill the idea, which is the point.

1. 1. Read the raw complaints. Not the summary. If the wording is mild or the thread is three years old, the pain is not urgent.
2. 2. Check the revenue ceiling. Across 8,000+ tracked startups the median earns about $145 per month and over 76% earn under $1,000. Know the realistic range for your category before committing a year.
3. 3. Find who already pays. An adjacent tool, a freelancer, or a spreadsheet somebody maintains. If nobody spends anything on the problem today, you are creating a budget, not capturing one.
4. 4. Talk to five complainers. Ask what they tried and what it cost them. If none will take a call, that is your answer and it cost you a week.

The full sequence, with scripts, is in our guide on how to validate a startup idea.

Why a data-backed rating beats a gut check

Founders rate their own ideas optimistically, and the people they ask are biased toward encouragement. A validator that reads complaint data removes both problems. If nobody is complaining about the problem your idea solves, that shows up immediately as a low demand score. CB Insights puts "no market need" as the top startup failure reason at 42%, which is exactly the failure this step is designed to catch.

Methodology and limitations

What this tool cannot do: tell you whether you will succeed. It lowers the odds of building something nobody wants. It does not replace talking to customers, and a high score is permission to investigate, not permission to build.

Frequently asked questions

What is idea validation?

Proving a problem is real and that someone will pay to fix it, before you build. It is not asking whether the idea sounds good, because almost everyone says yes to that. Validation looks for evidence that exists whether or not you show up: complaints, existing spend, and failed alternatives.

How do I validate a startup idea before building?

Score it here first to filter out ideas with no documented demand, then read the raw complaints, check what companies in that category actually earn, find who already pays to solve the problem, and talk to five people who complained. Four cheap steps, each able to kill the idea before it costs you a year.

Is this idea validation tool free?

Yes, with no signup. Paid plans add the full complaint threads behind each score, revenue benchmarks, competitor analysis and saved history.

What percentage of startup ideas are actually good?

Across 21,000+ recorded judgements on 1,100+ researched ideas, founders rejected 80.4% outright and only about 6% cleared majority approval. Treat a lukewarm reaction as normal. A narrow audience with acute pain beats broad mild interest.

How do I get unbiased feedback on a business idea?

Not from friends or from a model you have primed with your own framing, since both are biased toward agreement. Unbiased feedback comes from evidence that exists independently of you: complaints written before you had the idea, what comparable companies earn, and whether anyone already pays. That is what this tool scores.

How accurate is an AI idea rating?

A fast first filter, not a guarantee. Grounded in real complaint data rather than a model opinion, it reliably separates ideas with observed demand from ideas with none. It cannot tell you whether execution will work.

What should I do after I rate my idea?

Read the underlying complaints, calibrate revenue expectations against the category median, then talk to potential customers. Only then start building.
