I will not promote - serious question about readiness for Product Hunt

How do you know when your product is ready for Product Hunt.. I've got a few paid users now and a bit more development I would like to do.. But I feel like it's almost time to hit the gas and from reading posts here it was a game changer for a lot of startups - what do people think? Is it an intuitive feel or something more scientific to hit the market at the right time?
