Before you pick an idea — read this first
Quick answer
Before you start building anything on this list — do this one check:
The validation test
Ask them: “Would you pay for this?” Not would you use it. Would you PAY.
If two out of five say yes and ask when it will be ready — build it. If everyone says “sounds interesting” — keep talking to people first.
Every idea on this list has proven market demand. That does not mean your specific version will work. Validation before building is the difference between building something people want and building something people admire from a distance.
