I completely agree that validation is sought after in the wrong places. People feel that validation is defined by a valuation that was bloated by initial investors or by a few people saying they are interested.
That ain't the case. You need people to put their money where their mouth is. Bottom line.
However, imagine having launched Radfan March 2012 in a beta stage, inviting people to test the product at a reduced rate of purchase and report faults for you which only users would have picked up?
It would have enabled you to launch Radfan fully to the public without serious problems and would have made it possible for you to focus more resources on the marketing than to sit back for the first month and fix problems that arose.
Radfan looks like an awesome product for preventing hot air from escaping and actually going in the direction that you need it to. Good luck mate.
