01r/SaaS704k members
SaaS founders and operators
The audience already thinks in pricing, activation, churn, launch, and distribution tradeoffs.
What to post
Specific pricing/onboarding/retention questions with numbers; founder lessons explaining what changed.
What to avoid
Launch links, free audits, customer research asks, generic AI advice.
Key rule
Posts need a clear SaaS angle, not generic entrepreneurship or broad business news.
02r/microsaas193k members
Micro-SaaS builders and small software teams
Useful for smaller software bets where founders want practical constraints.
What to post
Narrow workflow problems for tiny software; pricing/niche feedback without links.
What to avoid
Treating community as free beta list or one-line idea validation.
Key rule
Posts should stay focused on micro-SaaS products and small software businesses.

Startup founders and operators
Helps when the SaaS question is more about company building, early traction, fundraising, or market choice.

Bootstrapped founders and indie hackers
Better fit for bootstrapped SaaS founders who want candid product and revenue discussion.

Growth marketers and startup operators
Works when the SaaS angle is an experiment, channel, or repeatable growth system.

Framing spam, scraping, automation, or hidden promotion as growth.

Product managers and product founders
Valuable when the SaaS founder problem is product strategy, discovery, roadmap, or prioritization.
