How much work did you do to validate the idea? Don't just ask people "Would you use this?" They will disproportionately say yes, because people like to be polite.

Instead, you could ask "What problems do you face? What solutions have you tried? How effective are those solutions?" If someone has not tried to solve their problem, they're not gonna care about your solution. If someone has tried to solve their problem and failed, then you know you have a killer painpoint.
