If anything, this wonderful piece of satire is overly generous. To put it more starkly: ideas are worthless. Only execution matters.
This is one reason that you should get over your “stealth-mode” start-up approach and talk about what you’re doing. In the vast majority of cases no one is going to “steal” your idea. There’s a reason for this: they don’t believe that your idea will work. Unfortunately, for most start-ups, they’re right. It will no work. So spend as little money as possible.
