Frequently Asked Questions
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 45-90 seconds. Complex ideas with extensive competitor landscapes may take up to 2 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.
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 If Your Next Idea Is a Dead End?
The average failed startup wastes $35,000 and 18 months. Find out in 60 seconds if your idea has legs — before you invest a single dollar.
