How to market on r/buildinpublic without getting banned
Founders building products in the open and sharing progress, metrics, and lessons. Indie founders and makers who document their journey publicly — a self-selected, supportive audience that actively wants to follow builders and the tools they use. Here's how to show up there the right way — and how FounderReply helps you do it on your own account, through Reddit's official API, with a human approving every word.
Your own account · official Reddit API · human-approved · no scraping, no bots
Open — sharing your product is on-topic. Member counts are indicative and change over time.
The rules that matter on r/buildinpublic
Sharing your product IS the format here — progress updates, launches, and behind-the-scenes are on-topic. The bar is that it must be a genuine build-in-public update, not a recycled ad.
- ✓Post genuine progress: what you shipped, what you learned, what broke.
- ✓Show real numbers (MRR, signups, churn) rather than vague hype.
- ✓Disclose it is your product — that is assumed here, but be explicit.
- ✓Engage with comments; drive-by self-promotion still reads as spam.
Subreddit rules change — always read the current sidebar rules before posting. This is guidance, not a guarantee.
How to actually win on r/buildinpublic
This community rewards transparency over polish. Post the honest arc of building your product — the wins and the setbacks — and let people follow along. Build-in-public audiences convert because they become invested in the journey before they ever see a pitch.
We don't do the things that get you banned
Reddit's 2025 spam crackdown removed roughly 70% of automated posting accounts, and tools that auto-post or operate "managed" accounts are exactly what it targets. FounderReply takes the opposite approach by design.
Your own account, official API
It acts as you through Reddit’s official API — never a scraper, fake persona, or rented account.
Human approval by default
Every draft waits in your queue. Growth comments on others’ threads are hard-capped to require approval.
Value-first, 90/10 by design
It surfaces threads where you can genuinely help and drafts useful contributions — promotion stays the exception.
ToS guardrails enforced
Per-platform automation caps mean the agent can never be set looser than Reddit’s policy allows.
r/buildinpublic marketing — FAQ
- Can I promote my product on r/buildinpublic?
- Sharing your product IS the format here — progress updates, launches, and behind-the-scenes are on-topic. The bar is that it must be a genuine build-in-public update, not a recycled ad. The safest approach: This community rewards transparency over polish. Post the honest arc of building your product — the wins and the setbacks — and let people follow along. Build-in-public audiences convert because they become invested in the journey before they ever see a pitch.
- Will I get banned for marketing on r/buildinpublic?
- You get banned for spamming, not for participating. The fast ways to get removed or shadowbanned are posting promotional content outside the allowed threads, using new or multiple accounts to push links, and posting at bot-like intervals. FounderReply does none of those: it acts on your own connected account through Reddit's official API, drafts genuinely useful contributions, and keeps a human approval step on by default — so what goes out is something you'd be comfortable posting yourself.
- Does FounderReply auto-post to r/buildinpublic?
- No — not unless you explicitly allow it, and even then growth comments on other people's threads are hard-capped to require approval. By default every draft waits in your queue for a one-tap yes. We never operate fake or "managed" accounts on your behalf; it is always your account, via the official API.
- What's the 90/10 rule on Reddit?
- Reddit's widely-cited self-promotion norm is that no more than ~10% of your activity should be promotional — the other 90% should be genuine participation. FounderReply is built around that ratio: it surfaces threads where you can genuinely help and drafts value-first contributions, so your promotional mentions stay the exception, not the pattern.
