Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.
Rule summary
- Share startup ideas and discussion: Posts should center on a startup idea, improvement, expansion, combination, or implementation.
- Invite useful critique: The strongest posts ask for feedback on a specific assumption, market, user, or execution path.
- Add enough context to evaluate the idea: Explain the customer, problem, current alternative, and why the idea may be timely.
- Avoid pure promotion: A link or pitch without an idea discussion is less aligned with the subreddit.
Works well
- Clear problem statements and target users.
- Idea critiques that ask about market, distribution, pricing, or feasibility.
- Expansions on other startup ideas with thoughtful reasoning.
- Early validation lessons without pretending the idea is already proven.
Avoid
- Landing-page copy disguised as an idea.
- Asking people to build the idea for you.
- Investment pitches or DM funnels.
- Vague ideas with no customer, problem, or differentiator.
What r/Startup_Ideas Is For
r/Startup_Ideas is for sharing and improving early startup ideas. For founders, it can be useful when the post is truly about the idea rather than an attempt to collect users.
What Works On r/Startup_Ideas
Strong posts define the user, pain, current workaround, possible solution, and the question you want the community to critique.
What To Avoid
Avoid pitching a finished product, requesting DMs, or making the audience do all the thinking. Idea quality depends on context.
