Why Market Research Matters Before You Build
Before committing months of development time to a SaaS idea, you need answers to at least five questions:
1. Is there a real market? (TAM/SAM)
2. Who are the existing competitors?
3. Who exactly is the target customer?
4. What should I charge?
5. How do I find my first users?
Traditional market research takes weeks and can cost thousands. Most founders skip it — which is one of the leading causes of building products nobody wants.

Honest Caveats
From the platform's own documentation:
> *"While we strive for accuracy, reports should be used as one input in your decision-making process."*
AI-generated market research is a useful starting point — not a replacement for customer interviews, primary research, or deep domain expertise. Use it to orient your thinking and direct your next research steps.
Your submitted ideas are **kept confidential and not shared with third parties**. Refunds are available for reports that don't meet quality standards.
