When is the best time to launch on Product Hunt? Still in beta or once launched publicly?

Hi indie hackers,

Earlier this year my co-founder and I started bootstrapping Floq (www.gofloq.com), an super easy coordination tool for hybrid teams that lives within Slack. We are still in private beta, but start planning our public launch. Obviously, Product Hunt comes into play now.

Does anyone have any best practices when it comes to timing the launch? Should you do it once the product is still in private beta or only once it is publicly available?

Thanks a lot!!
