A source-backed Rankhog guide to r/roastmystartup: public rules, community context, posting fit, and startup-promotion risk before you publish.
By Anthony Riera, founder and operator of Rankhog.
Subreddit guides combine public Reddit source URLs, captured rules, visible verification dates, and Rankhog's account-safety workflow.
Current public stats
Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.
Reddit describes r/roastmystartup this way: Post your start-up (or start-up idea) for other entrepreneurs to roast it. We won't hold back punches.
For Rankhog planning, treat it as a place for product critique, launch feedback, testers, and early-user learning. Use the source description and the visible rule list before deciding whether a startup post belongs there.
The fetched old Reddit rules include "No ProductHunt Links, Vercel Links, just a Link or free subdomains", "No Reporting People for BS", "Lack Of Effort or not Roast", "AI Slop". The rule to read twice is "No ProductHunt Links, Vercel Links, just a Link or free subdomains". It is the clearest source-backed warning against turning the subreddit into a launch, link, or sales channel.
A strong post gives the community something to answer, inspect, or learn from before it asks for attention. Bring the audience, stage, constraint, what you tried, and the exact question.
Good fits include:
Do not use r/roastmystartup as a cold launch channel. The safest draft should still make sense if the company name, product URL, and call to action are removed.
Watch for:
Use this page as a pre-flight check. If the rule note and the community description do not support the post, choose another subreddit or turn the idea into a comment, lesson, or question first.
