r/buildinpublic: self-promotion rules & buyer-intent guide

Allowed with conditions~55K members · 7 published rules · checked 2026-07-02

r/buildinpublic exists for sharing work-in-progress openly, so self-promotion is structurally allowed — but not without context. Posts must center progress, lessons learned, or feedback requests rather than pure promotion. Spam links mean immediate removal, and shared tools or resources must be transparent about being paid, free, or affiliate-linked.

No self-promotion without context
Share your work openly, but the post must carry progress, lessons learned, or a feedback ask — not exist solely to promote.
Stay on the build-in-public topic
Posts must relate to building in public — a product, a skill, a launch. Off-topic content is removed.
No spam
Spamming links, irrelevant content, or unsolicited ads leads to immediate removal.
Tool transparency
If you share tools or resources, disclose whether they're paid, free, or affiliate-linked.

What buying intent sounds like on r/buildinpublic

Promotion rules limit how you can talk — they don't stop buyers from talking. These are the phrase patterns that signal a potential customer in this community:

  • what are you using to find users
  • day N of building X — stuck on distribution
  • how do you decide what channel to focus on
  • launched and got zero signups — what now
  • which analytics/marketing tool for an early product

  2. 02Weekly build-in-public update with one distribution experiment

FindEvo watches r/buildinpublic for these buying signals — and keeps you inside its rules.

It scores every new post for buying intent, flags each subreddit's self-promo policy before you engage, and never sends a message for you — you reply in your own voice, which is exactly what these communities' rules reward.
