How we compared
We make CommunityMentions, so we're one of the 15, and we rank it first. Here's how we compared, so you can check it. On September 29, 2026 we read the 8 lists of agencies for B2B SaaS that Google ranks or AI engines cite for that question. Six of them rank their own publisher first. We took the 9 agencies that appear on 3 or more of those lists and have a Reddit service page, then added five that appear on one or two lists, sell Reddit programs to B2B companies and state a price on their own site: Karma Alien, Soar, GrowReddit, Verticality and Discovered Labs. Three that appear on 3 or more are left out: Accelerated Digital Media has no Reddit service page, Sociallyin states no B2B or SaaS focus, and Skale's service page doesn't mention Reddit.
We ranked on five things a B2B SaaS team buying organic Reddit presence needs, using only what each agency's own site says: it places organic comments in buyer threads for you (not ads only, and not drafts you post yourself); it publishes a price; it has no minimum term; it states a B2B or SaaS focus; and the same plan also places comments beyond Reddit, on YouTube, LinkedIn, Medium or X, where AI answers pull from too. Every agency's pricing and Reddit page was re-read on October 22, 2026. Ties go to the lower published entry price, then to the agency on more of the 8 lists. Reddit Ads aren't a criterion: if you want ads, see the last section.

The agencies, ranked
- 1. CommunityMentions, us, and the only agency here that meets all 5. We find threads where buyers ask for recommendations, AI drafts the comments, you approve the voice in Slack, and real people with established accounts post them every day on Reddit, YouTube, Medium, LinkedIn and X. $1,000 a month, month-to-month, and the sample is free. We don't run Reddit Ads, write long posts or run AMAs; the last section names who does.
- 2. SaaSy Links, which works only with B2B SaaS companies. Organic posts and comments at $650 a month (3 posts and 10 comments), $1,300 (7 and 20) or $2,000 (10 and 30), month-to-month, and it replaces any placement removed within 6 months. Reddit sits next to its SEO and link-building services.
- 3. Verticality, a Toronto digital agency whose Reddit service sells organic threads, comments and Reddit Ads to B2B SaaS, DTC and regulated brands. From $1,900 a month (up to 4 subreddits and 2 threads a week) to $5,000, month-to-month with 30 days' notice. It says it uses no bots and no bought upvotes, and posts from named accounts that disclose the relationship where a community expects it. Its own list ranks it first.
- 4. Discovered Labs, an AI-search agency for B2B companies that includes Reddit in its retainers: 10 Reddit mentions a month on its Establish plan at €6,995 a month ($7,995) on a 6-month commitment or €7,995 ($9,138) month-to-month, from aged accounts run by its own team, with 30 days' notice. Pricing page re-read October 22, 2026; it no longer lists a Reddit add-on price. Its own list of B2B SaaS Reddit agencies places it fifth.
- 5. Karma Alien, Obility's Reddit-only brand for B2B SaaS and tech: commenting in brand, keyword and competitor threads, posts written for AI search, branded subreddits and Reddit Ads. $1,850 a month for up to 20 comments, or $2,500 and $4,950 with a branded subreddit and AI-search posts; ads management is $750 a month on top, with at least $2,500 a month in ad spend that you pay Reddit directly. No minimum term on its pricing page, and LinkedIn exec posts are a separate $1,000-a-month add-on, which is why it meets 3 of 5. Obility's own list ranks Obility first and Karma Alien second.
- 6. GrowReddit, a Reddit agency for B2B SaaS that runs paid and organic together. From $2,999 a month for 20 posts and 20 comments, or from $4,999 for 50 of each, with a 3-month minimum. It says every post and comment is written by a person and posted by hand.
- 7. Growthner, which says it works only with SaaS companies. Organic posts, comments and AMAs with no lock-in contract; its Reddit page no longer shows a price (re-read October 22, 2026), and its pricing page lists AI-search plans from $2,500 a month. Reddit is one of several services, next to SEO and link building. It appears on 5 of the 8 lists, more than any other agency.
- 8. OutreachBloom, which sells Reddit marketing next to AI SEO and B2B outbound and says it's built for B2B SaaS and services companies. $1,900 a month for 50 community engagements (pricing page re-read October 7, 2026), drafted daily for you to post from your branded account; its AI SEO plan, $4,900 a month on its November 9, 2026 pricing page, adds content and citation work.
- 9. Foundation, which calls itself the AI visibility agency for B2B tech and SaaS. It runs organic and paid Reddit: subreddit analysis, content plans, community engagement, AMAs and Reddit advertising. No price on its service page; its own list puts it at custom pricing from about $1,000.
- 10. Growth Marketing Pro, a growth agency with a B2B SaaS practice that added an organic Reddit program to its search work and also runs Reddit Ads. No published price.
- 11. Infrasity, a developer-marketing agency for B2B SaaS and developer tools. With your approval it posts comments and threads from high-karma accounts, and runs Reddit Ads if they suit you. No published price; its Reddit page states a 3- to 6-month minimum, and it says it isn't a fit for non-technical audiences.
- 12. Single Grain, a full-service agency that describes itself as a B2B SaaS marketing agency. Reddit posts, comments and AMAs, Reddit advertising and community management, priced by custom proposal.
- 13. Soar, a Reddit-first agency up since 2017 that works to rank threads for a category's buying searches, then layers Reddit Ads on the threads already doing well. It has no pricing page and asks you to request a proposal; its own blog lists it at $5,000 to $15,000 a month. Its Reddit page also links to a separate service that sells Reddit upvotes.
- 14. Taktical Digital, a performance agency with a SaaS practice whose Reddit service leads with ads: strategy, monthly creative and tracking, plus AMAs and organic engagement. No published price. Its site says it's now a MediaMint company.
- 15. InterTeam, a B2B advertising agency for SaaS and a certified Reddit Ads partner. It runs Reddit Ads, its site lists no organic Reddit service, and its own blog states a $5,000 minimum project size.
Where B2B software comments land
We run daily comments for B2B software companies, and our delivery data says where to look first. Of the 8,047 Reddit comments we verified for 22 B2B software client brands between January 28 and September 28, 2026, 5.7% landed in founder and startup subreddits like r/SaaS and r/startups, and 88% in 1,565 topic subreddits led by r/AI_Agents (489 comments), r/LocalLLM (165) and r/GithubCopilot (163). r/SaaS came sixth, with 147.
Ask any agency on this list which subreddits it would work for your product. If the answer is r/SaaS and r/startups, it's aiming at subreddits that got 5.7% of our B2B software comments. The full table is on Reddit marketing for SaaS.
Questions to ask before you sign
- Which subreddits would you work for my product, and why those?
- Organic, Reddit Ads or both? If ads, is the ad spend inside your fee or on top of it?
- Do I get a link to every comment and thread, and how do you count the ones moderators remove?
- Who writes the comments, and whose accounts post them: yours, a network's, or mine?
- What's the minimum term, and what happens to my accounts and threads if I stop?
When another agency fits better
- Reddit Ads. Karma Alien, GrowReddit, Soar, Verticality, Foundation, Taktical, Growth Marketing Pro, Infrasity, Single Grain and InterTeam run paid Reddit campaigns. We don't.
- Strategy, long posts and AMAs. Soar, Foundation, Single Grain and Growthner plan campaigns and run AMAs, and GrowReddit ships 20 posts a month on its entry plan. We place comments.
- Branded subreddits. Karma Alien sets up and manages branded subreddits. We don't.
- Comments written by people. GrowReddit says a person writes every post and comment. Ours are AI-drafted, and you approve the voice and filters in Slack before anything posts.
- Replacement guarantees. SaaSy Links replaces any placement removed within 6 months. Our daily report counts comments removed before our same-day check; since October 6, 2026 a later removal shows as removed on the client dashboard and drops out of the weekly and monthly reports, it steers which subreddits we work, and our published terms don't include replacements.
