You have tried the business idea test and you want to go further? Go premium and ask for a full evaluation of your idea.
Evaluating your idea fully before you launch it is the best way to avoid disappointment in the long run. You may think you'll always be able to change things down the road but experience shows the more you wait the more difficult it becomes.
On the contrary, things are much easier to adapt at the idea stage. Always make sure you're taking the best route before you start a long journey.
