Can you promote here?
The written rules take no clear position, which is NOT permission: unclear communities enforce norms through removals instead of rulebooks. Sort by top, study which builder posts survived and how they were framed, and when in doubt ask the mods.
From the rules · Self-promotion and product links are commonly accepted in practice — post as a helpful intro/’drop your startup’ thread rather than a blunt ad.
Links
The rules clearly allow links. A plain-text mention still often outperforms a URL from a young account.
What this community rewards
Dominant post formats: showcase, discussion, question
Headline: short imperative or invite (e.g., “Drop your startup”, “What are you building?”). Write in first person, concise post body (about 50–300 words) with one clear ask. Tone: direct, helpful, traction-focused. Posts that give concrete value (metrics, offers to help, request for feedback) get upvoted; vague or rude posts get ignored or downvoted.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked August 2026. Rules change and moderators have the final say: verify at r/startup_ideas's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
