NDA before pitching? Really?

If you think you need an NDA before pitching your startup idea, you need to read this.

Operating in "stealth mode" does more harm than you realised:

1. Little to no validation of your startup idea

2. No well-wisher to warn you of relevant trends or information that may help you correct your path

3. No potential talents working on the same problem know you

4. Nobody knows what you're doing - no good fortune comes to you

5. Makes you look silly
