The best subreddits for business, measured by how many posts come from buyers

We built profiles for 38 communities where B2B buyers might show up. For each one we sampled recent posts on 17 and 18 October 2026 (35 on the 17th, and r/taxpros, r/marketing and r/indiehackers on the 18th). We scored every post for buying intent, meaning whether the person wants to buy a product or hire someone. The "reading as buyers" column is the share of sampled posts that did. We also read each community's posted rules and summarised what they let sellers do.

A sample of 100 to 300 recent posts is a snapshot. It isn't a census. A community's share can move a few points from month to month, and a low share in a huge community can still add up to a steady flow of requests. The full method, including how we handle quotes and vendor posts, is in how we research Reddit. Each community name below links to its full profile, with rules, sample requests and similar communities.

IT people ask each other what to buy more openly than almost any other group. r/msp tops the whole list. Owners of managed service providers compare security tools, PSA and RMM platforms and Microsoft 365 add-ons in public, and vendors are welcome as long as they say who they are and keep pitches in the weekly thread. r/sysadmin and r/cybersecurity are bigger but noisier, so replying in an existing thread works better than starting a new post.

r/taxpros is small, and the practitioners there ask about practice software, client portals and review tools. Its rules don't mention promotion. That doesn't give you licence to pitch, so answer the question asked and disclose if you sell something. r/Accounting is fourteen times the size of r/taxpros, but only 2% of its posts read as buyers because it is mostly a career community.

Store owners often ask about inventory, fulfilment and apps. Both communities ban promotion outright, and r/ecommerce also bans posts asking for services. Use them to learn which problems come up most and how merchants describe them, then reach those buyers somewhere that allows it.

Marketers and salespeople are the hardest group to sell to on Reddit. They recognise a pitch on sight, and most of these communities ban one. There are still buyers here: agency owners ask about reporting and white-label help, and r/copywriting gets requests for writers. The large general communities, r/marketing and r/sales, sit at 3%, so use them to understand the job rather than to find leads.

These are professional communities, and they don't allow promotion. HR people ask about payroll, PEOs and benefits often enough to reach 8%, but you can only answer as a peer, with no links to what you sell. If you sell into these roles, read the threads to learn their problems and the words they use, and do your selling somewhere else.

Tool communities are where people ask for an implementation partner, an integration or an add-on for software they already pay for. r/hubspot and r/zapier are small, but a seller who knows the product can answer a recommendation request there directly. r/salesforce allows product mentions if you disclose your interest and show full pricing. Copy that rule in every reply you write.

Most lists of the best subreddits for entrepreneurs and small business put these communities first, and they are the biggest here: r/Entrepreneur alone has 5,295,402 members. Only 4% to 7% of posts come from buyers. In absolute terms that still adds up to requests, but every other seller is watching the same threads. On r/smallbusiness, the business subreddit most owners know, you can only talk about what you sell in the weekly promotion thread.

Builder communities are mostly people making things rather than buying them. Founders use r/SaaS and r/indiehackers to share launches and ask for feedback, so only 2% and 1% of their posts read as buyers. They work for product feedback and badly for finding customers, even though many lists of subreddits for B2B rank them near the top.

• Follow the rules shown, then read the full list. The summaries above are short, and moderators change the rules, so check the current ones with the subreddit rules lookup before you post.
• Answer the question the person asked, with specifics, before you mention what you sell. If the answer doesn't need your product, leave it out.
• Say you work on the product whenever you mention it. Several of these communities require that disclosure, and readers trust it everywhere else.
• Where a community keeps promotion to a weekly or fortnightly thread, post there and nowhere else.
• Look at nearby communities too. The similar subreddits tool suggests smaller ones around any community on this list, and they often have fewer sellers and the same buyers.

For the full method, from finding threads to qualifying a post and writing the reply, see Reddit lead generation for B2B. The communities directory has every profile in one place.

Pick the two or three communities above that match what you sell, open their profiles, and note the requests they show. If you'd rather not check them by hand, paste your company website into HearBuyers. It suggests communities like these, reads their public posts along with X, and scores each post from 0 to 100 for buying intent. Then it drafts a reply for you to approve and post yourself. It's free for 14 days, then from $19 a month.
