Niche subreddit is a small-to-mid-size Reddit community organized around a specific topic, profession, or problem, like r/SaaS or r/podcasting, as opposed to massive general-interest subreddits.
Why it matters
Niche subreddits are where buying decisions actually happen. Their members are self-selected practitioners, so "what tool do you use for X" threads there carry real commercial intent, and because the discussions are specific and expert-dense, they're disproportionately what Google surfaces and AI engines cite when answering category questions. For a SaaS founder, five relevant niche subreddits beat one giant one: less noise, mods you can build a relationship with, and threads that stay findable for years. The tradeoff is stricter norms, small communities detect and punish drive-by promotion instantly.
How to use it
