Book a 30-minute call →Rarely the ones named after your category. B2B software buyers spend their Reddit time in role and stage communities, asking peers what to buy, not in vendor subreddits reading announcements. The ten below are ranked by how often people in them describe the problem your product solves in their own words, which is the signal that predicts whether a comment gets replies or gets removed.

Founder cluster with high engagement on operator playbooks. Lower volume than r/Entrepreneur, higher signal.
The ones where somebody has already decided to leave and is asking what to move to. Those threads carry budget, a deadline and a named incumbent, which is why a single useful reply in one outperforms a month of posting into the category at large. Each thread below cleared the velocity, intent-vocabulary and bot-mix passes described under the shortlist methodology.

How FORKOFF runs this
The placeholder above is what the personalized render looks like once Phase D-2 wires the live Reddit API plus Claude synthesis. FORKOFF caps this at 5 engagements per quarter, per our own delivery capacity, all tracked in the audit ledger at qualified views per dollar. Our playbook on Reddit marketing for B2B founders details the thread cadence behind it.
What the shortlist returns, where the data comes from, how a switching moment is scored, and what happens on the call. These are the questions teams ask before they run a Reddit motion for the first time, answered without the hedging, including the parts of this tool that are still example output rather than a live per-domain render.
Two lists for one domain. Ten subreddits where that company's buyers already post, each with the member count and the reason it made the cut, and three threads from the past week where somebody is actively switching away from a tool in the category. The subreddit list tells you where to be. The thread list tells you what to say this week, which is the half most Reddit advice skips.
Not yet. What renders here today is a worked example against B2B SaaS targets, and it is the same shape the personalized version returns. Live per-domain generation is in active build. Until it ships, a FORKOFF strategist runs the analysis by hand against your domain on a 30 minute call, which is the same output with a person attached to it.
A category mention is somebody talking about the space. A switching moment is somebody with budget, a deadline and a complaint. The classifier scores three things: thread velocity in comments per hour, intent vocabulary in the comments such as pricing, vendor, quote and switching from, and a bot-mix exclusion pass. Threads that clear all three are the small fraction worth a same-week reply.
Reddit's official public API for the threads and subreddit metadata, scored against FORKOFF's own switching-moment classifier, which was trained on a 50,000-thread corpus. Nothing here is scraped from a logged-in session and nothing is inferred from a third-party reseller's index.
Because posting everywhere is how an account gets removed. Reddit moderation is per-subreddit and unforgiving of pattern posting, so a shortlist that a single operator can genuinely participate in beats a long list nobody works. Ten is roughly what one person can read daily and comment in credibly, which is the constraint that actually governs results.
Thirty minutes with the strategist who would run the engagement, not a sales seat. You leave with the shortlist run against your own domain and the thread angles for that week, whether or not you engage FORKOFF afterwards. FORKOFF caps delivery at five engagements per quarter, so the call is also where we say plainly if there is no capacity this cycle.

Methodology
Shortlist signals draw from Reddit's official API plus FORKOFF's switching-moment classifier, which scores thread velocity (comments/hour), commenter intent vocabulary (pricing/vendor/switch-from triggers), and bot-mix exclusion against a 50K-thread training corpus. Outputs are ranked by qualified-engagement probability per the audit-ledger methodology.
