Define the problem. Write some code to solve the problem. Ask people who have that particular problem to give you money. Ask them if they know others who have the same problem. Finally ask them if they have other problems you can solve. Then repeat.
The validation happens the moment you ask someone for money. You'll know either way quite quickly.
