Why I Built This
I've built 4 products in the last 3 years. Three of them failed.
Not because the code was bad — I'm a decent engineer. They failed because I never checked if anyone actually wanted what I was building. I'd get excited about an idea, spend months coding, launch to silence, and wonder what went wrong.
The third failure cost me 5 months and a lot of motivation. After that one, I finally did what I should've done from the start: I spent a week researching the market, checking competitors, running the numbers. Turns out, 20 minutes of research would've saved me 5 months of wasted work.
That's when I realized: the problem isn't that founders are stupid. It's that validation is boring, slow, and easy to skip. So I built IdeaKiller — to make validation so fast and cheap that there's no excuse not to do it.
If even one person avoids my mistakes, this was worth building.

FAQ
Startup Idea Validation:
Your Questions Answered
How accurate is the AI validation?
Our AI uses real-time web search data, market research databases, and proven frameworks. While no validation is 100% accurate, we provide the same analysis quality as expensive consulting firms — at a fraction of the cost and time.
What data sources do you use?
We combine real-time web search results, market size databases, competitor analysis, and AI-powered reasoning. All data is fresh and pulled at validation time.
Can I validate any type of business idea?
Yes! IdeaKiller works for SaaS, mobile apps, marketplaces, physical products, services, and more. The AI adapts its analysis to your specific business model and industry.
How long does a validation take?
Most validations complete in 1-2 minutes. Complex ideas with extensive competitor landscapes may take up to 3 minutes.
What if I disagree with the verdict?
The verdict is a recommendation based on data, not a final decision. You know your market best. Use the report as input, challenge the assumptions, and make your own call. That's why we show all the data and reasoning.
Do you store my ideas?
Your ideas are stored securely and never shared with third parties. You can delete your validation history at any time. We use enterprise-grade encryption.
Do I get any free credits?
Yes! Every account receives 3 free validation credits every month, automatically. No credit card required.
Is there a money-back guarantee?
Yes! All paid plans come with a 14-day money-back guarantee, no questions asked. If you are not satisfied, we will refund your purchase.
What is startup idea validation and why does it matter?
Startup idea validation is the process of testing whether your business idea has real market demand before you invest time and money building it. 9 out of 10 startups fail — and 42% fail because they built something nobody wanted. Validation checks demand, competition, unit economics, and product-market fit so you know before you build, not after you launch.
How do I validate a business idea before building?
Traditionally, founders spend weeks on manual market research, competitor analysis, and financial modeling. IdeaKiller automates this entire process: describe your idea, and our AI runs demand analysis, competitor research, unit economics calculations, and risk assessment in under 3 minutes — giving you a clear GO/NO-GO verdict backed by data.
How much does it cost to validate a startup idea?
Hiring a consultant costs $5,000-$15,000. Doing it yourself takes 2-4 weeks of research. IdeaKiller validates your idea for $14 in under 3 minutes — and your first validation is free every month. The average failed startup wastes $35,000, so the cost of not validating is far higher than the cost of validation.
Every week you wait is another week you could be building the wrong thing.
