Stealth mode is a way to to focus on what&#x27;s important: get the product finished, rather than to have to deal with the outside world. It rarely if ever has to do with keeping the idea secret. First mover advantage is worth protecting too, as well as a change of direction in case your great idea does not work out after more time is invested in implementing it or if you realize there are even greener pastures.<p>Stealth mode - and secrecy in general - is a tool, but the day you open the doors to your first users the competition will be able to look at what you&#x27;ve made and then the clock to locking up the market is ticking.<p>This is extra important when it comes to ideas that have network effects.
