Ask HN: How do you validate your idea?

I ask people for money [0]. If some people pay [1], the idea is valid. If nobody does, it isn't. Depending on how much money I get from the people who pay and my costs, I decide if the valid idea is viable. [2] Money changing hands is the only reliable signal in business.

If something is easier than getting paid, it isn't hard work. Good luck.

[0]: Asking people if the would pay is not equivalent.

[1]: Promises to pay are not equivalent.

[3]: Not all valid ideas are viable.
