How do you think, how the Product Hunt can be useful if you are not going to launch any product?

Hi Ivan! Great to connect with you! I'm Tao, cofounder and CEO behind MindOS. We're launching MindOS Memory Twin this Sunday! 🚀 I would greatly appreciate it if you could stay notified and support us on the launch day: https://producthunt.com/products.... Thank you so much! Best regards, Tao

It's a good way to connect with fellow entrepreneurs. Much better than Linkedin.

You can still use PH to prospect your ICP if you feel it would work! You use it also to gain visibility or to make market research.

You can exchange experiences, seek advice, and sometimes they offer valuable insights.

You may use it's discussion functionality to give and invite them to your offering. I assume you have a landing page at least.
