Is Product Hunt good for finding beta users?

Hi everyone , Mark here. I created an account a few months ago, but this is my first post.

Quick question: if I’m looking for beta users right now, is Product Hunt a good place to start?
How do makers usually promote a product here — do you start with a pre-launch page, or only post on launch day? And what actually works (without feeling spammy)?

Any tips or examples would be super appreciated. Thanks!
