Can I mention my own product in a post if it relates to space?
No. The rule against advertising and promotion covers any kind, and a space connection does not change that.

Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.
Rule summary
- No Hate Speech: No hate speech allowed whatsoever.
- Be Respectful: No arguing or insulting anyone.
- No Advertising: We do not allow advertising or promotion of any kind.
- No Low Quality Posts: All low quality and low effort posts should stay in the Daily Discussion Thread.
- No Posts Of Stock Charts: Posts of stock charts should only be in the Daily Discussion Thread.
- Posts Should Be Related To Rocket Lab: Posts should be related to Rocket Lab.
Works well
- A thoughtful text post about Rocket Lab news, launches, or business developments, written in your own words and clearly on topic.
- A question about Rocket Lab's technology or missions that invites discussion rather than pitching anything.
- A short, low effort thought or a stock chart posted inside the Daily Discussion Thread instead of as its own post.
- A genuine observation about the company that gives members something to talk about, with no link to your own product or service.
Avoid
- Posting a link or a pitch for your product, service, or newsletter, which breaks the no advertising rule outright.
- Posting a stock chart as its own post instead of putting it in the Daily Discussion Thread.
- Dropping a low effort one liner on the main feed when it belongs in the Daily Discussion Thread.
- Posting about the space industry in general with no clear connection to Rocket Lab.
- Getting into insults or arguments in the comments, which breaks the respect rule.
- Any form of hate speech, which is banned with no exceptions.
What r/RKLB Is For
This is a community about Rocket Lab, the company behind the ticker RKLB. The description is short and to the point, and the rules back that up with a rule that says posts should be related to Rocket Lab. So the room is for people who follow the company, its missions, and its stock. The rules also point to a Daily Discussion Thread, which tells me the regulars keep quick takes and chart talk in one place and want the main feed to hold real posts. If you show up here, you are a guest in a company focused community, not a marketplace.
Rules That Matter Before Posting
The rule that decides everything for a founder is “No Advertising”, which says they do not allow advertising or promotion of any kind. That is about as strict as promotion rules get, so any post that smells like marketing is gone. “Posts Should Be Related To Rocket Lab” matters next, because even a well written post gets removed if it drifts off topic. “No Low Quality Posts” pushes anything low effort into the Daily Discussion Thread. “No Posts Of Stock Charts” does the same for charts, which matters if you were thinking of posting a chart to make a point. “Be Respectful” and “No Hate Speech” round it out, and they apply to how you argue in the comments too.
What To Post
A good post here is directly about Rocket Lab and gives people something real to discuss. Write it as a full post with some thought behind it, not a quick one liner, because anything low effort belongs in the Daily Discussion Thread instead. If what you have is a quick thought, a chart, or a half formed idea, put it in the Daily Discussion Thread and save the main feed for posts with more substance. If you are a founder, the honest play is to participate as a member first. Talk about the company, ask questions, and build a reputation before you ever think about mentioning what you do. And when you do speak about your own work, keep it out of the promotional lane entirely, because this community has drawn a hard line there.
What To Avoid
The fastest way to get removed is advertising or promotion of any kind, so leave your product, your link, and your pitch at the door. Do not post stock charts as their own posts, because those are only allowed in the Daily Discussion Thread. Do not post anything low effort or low quality on the main feed, same reason. Do not post about anything unrelated to Rocket Lab, because off topic posts get removed. And keep it civil, because arguing or insulting people breaks the respect rule and hate speech is banned completely.

Common questions about r/RKLB
Where do stock charts go?
Only in the Daily Discussion Thread. A chart posted on its own on the main feed breaks the stock chart rule.
I have a quick take that is not a full post. Where does it go?
The Daily Discussion Thread. The low quality rule sends all low effort posts there.
Can I post about the broader space industry?
Only if it ties back to Rocket Lab. The rules say posts should be related to Rocket Lab.
What happens if I get into an argument in the comments?
Arguing or insulting anyone breaks the respect rule, so keep disagreements calm or step away.
