If you are in r/saas, you are looking to make products or searching one.
I'm Irbaaz, I have been in SaaS industry for few years, sharing my learnings for young people.
If you are new, start by taking small steps daily, treat it like marathon.
Start by small helpful posts on different platform, form connections through comments and dms and start networking daily.
Do heavy research on ideas before spraying and praying. Do not follow the crowd who build first and market later. It only works out for ideas that has been validated heavily.
Talk to others and try to form some bond, try to build small group you stay accountable to, if it's users more better.
You can believe in virality and try your luck with short forms but don't depend on it but never give up before trying it out who knows luck might be on your side.
Gather resources, learns best practice, keep trying out different channels.
Never forget to have fun while you grow.
