Stay alive long enough to become an overnight success

Great successes are rarely created overnight, companies often develop their product too early (it is a lot easier to figure out when you are too late for a market). If you really think your ideas is going to take off then sell what product you can, keep advocating, and stay alive until customers realize you were right and the time is now. Then get irritated later when people point out how easy it was for you to become a success overnight.
