1. Is there demand?
Search competitors, hashtags, reviews…
If nobody is selling it — that’s a red flag.
2. Are people willing to pay?
Likes ≠ sales.
Only money proves demand.
3. Do you understand your customer?
Who are they?
Where do they live?
What problem are they trying to fix?
4. Can you test the idea cheaply?
Start with a landing page
or a WhatsApp catalogue
or sell to friends & colleagues.
5. Are you solving a real problem?
People pay quickly for pain relievers.
Conclusion
Validate first. Spend money later.
