Alternatives to Product Hunt? I will not promote

I recently launched my business, any ideas on where can I showcase my startup? As they say the first 3 months are the hardest. It’s been almost a month. Once you build, you want people to know what you are doing. How do you get it out there? Where can you get genuine feedback? Is there a community where you can build together and motivate each other? I’ve built something I truly believe in and will give other founders a voice as well.  I’m now in that phase where I need to get the word out, attract users, and gather feedback. I have looked at the following - * Product Hunt * Indie Hackers * Betalist * StarterSky * Failory * startups .fyi * Indievoice Any other sites one can look at? Are there any **great communities, Discord groups, or Slack channels** where founders can chat and be part of? Motivate each other, become part of a support group or even just bounce of ideas? Compare notes on how each one is building their business and push each other to grow? Adding to this question ; For those of you who have launched something, how did you reach your first 1,000 users? Did you leverage Reddit, LinkedIn and social media? Friends and family can help to an extent but beyond that how does one really get out there with a limited budget? Cold calling? Cold outreach? Partnerships with others? Collaboration or just looking closely at your competition and learning from that? Any insights or experiences would truly be appreciated.
