Picking subreddits for lead generation · how to use

The shape that works: 2 general, 3–5 niche, 1–2 adjacent.

Most founders pick subreddits wrong. They jump to the largest community in their space — r/Entrepreneur, r/marketing — and get buried under 800k subscribers and a wall of "just shipped my SaaS" posts. The good leads are deeper.

Pick 6 to 8 subreddits in three tiers:

  • 2 general subs for accidental discovery (r/SaaS, r/Entrepreneur, r/startups).
  • 3 to 5 niche subs where your target customer self-selected (r/indiehackers, r/SideProject, r/EntrepreneurRideAlong for SaaS — your equivalent for whatever you sell).
  • 1 or 2 adjacent subs where your customer hangs out for a different reason.

Use this subreddit finder to find candidates — search the problem your product solves, then check subscriber count and activity. A 200k-subscriber sub with 5k online is usually more useful than a 900k sub with 12k online: better signal-to-noise.

Already know you sell B2B? Skip the search and start from our curated directory of the best subreddits for B2B lead generation, grouped by category — SaaS, marketing, e-commerce, freelancing, and more.

Frequently asked questions

What is a subreddit finder?

A subreddit finder is a tool that takes a keyword or topic and returns the Reddit communities (subreddits) most relevant to it. Instead of guessing subreddit names or browsing Reddit manually, you search a term and get a ranked list with subscriber counts and activity, so you can quickly see where a given audience actually gathers.

Is this subreddit finder free?

Yes. The LeadsRadar subreddit finder is completely free with no signup, no card, and no usage limit. It queries Reddit's public community index and returns up to 25 matching subreddits per search.

How does the subreddit finder work?

Type any keyword — a product category, an audience, a problem, or an interest. The tool searches Reddit's community index and returns the 25 most relevant subreddits, sorted by subscriber count, each with its description and live online-user count so you can judge how active it is.

How do I find the best subreddit for my niche?

Search the problem your product solves rather than your product category — you'll surface the communities where buyers describe pain, not just where competitors market. Then weigh subscriber count against activity: a 200k-subscriber sub with 5k online usually beats a 900k sub with 12k online on signal-to-noise.

How many subreddits should I target for lead generation?

Six to eight: two general subs for accidental discovery, three to five niche subs where your customer self-selected, and one or two adjacent subs. More than that and the noise drowns the signal. Our curated B2B subreddit directory groups them by category to make this faster.
