Common questions about finding and posting in SaaS subreddits.
r/SaaS and r/Indiehackers consistently produce the highest-quality signups because the audience is self-selecting. These are people who buy and use SaaS tools professionally. r/Entrepreneur has higher volume but lower conversion. The best strategy is to post in all three with adapted framing for each community.
Yes, but not within the same month and never with the same content. Monthly update posts ("3 months since launch: here is what happened") are a legitimate way to post regularly without being seen as spam. Space posts at least 30 days apart and always add new information.
r/SaaS itself does not have a high karma requirement, but Reddit's spam filters flag link posts from new or low-karma accounts. Having at least 100 combined karma and a 30-day-old account significantly improves your post survival rate.
r/SaaS explicitly allows self-promotion posts more freely on weekends. For r/Entrepreneur and r/startups, Tuesday through Thursday mornings (US Eastern time) tend to have the highest engagement. Use the Best Time to Post on Reddit guide for specific timing data.
