How to build a community on X from your first 20 members
Short answer
Start with about 20 people who already post about your topic. Find them with X search, add them to a public List, invite them by reply with a clear reason to join, give the group one hashtag and one regular weekly thing to do, and post the List and tag in a pinned post so newcomers can find you.
- Twenty active members are enough to make a feed worth reading.
- Find people by what they post, not by follower count.
- A weekly ritual, such as a thread or a hashtag chat, matters more than a launch announcement.
- Ask before adding someone to a public List that names a group.
Since X closed Communities in May 2026, there is no button that creates a group. A community on X is now something you assemble: a List of members, a hashtag and a few saved searches. That sounds like more work, and for the first few weeks it is. The upside is that nobody can switch it off. This guide covers the hardest part, the first 20 members, and the habits that keep them posting.
Who should your first members be?
Your first members should be people who already post about the topic at least weekly, whatever their follower count.
Follower counts tell you little about whether someone will take part. A designer with 300 followers who posts work-in-progress every few days is worth more to a new group than a well-known name who posts twice a month. Look for:
- People who reply to others on the topic, not only broadcast.
- Accounts with a mix of their own posts and conversations.
- A range of experience, so beginners have someone to ask and experienced people have someone to help.
Write the group's purpose in one sentence before you start looking. "UK hobby beekeepers sharing hive photos and questions" tells you who fits and who doesn't.
How do you find them on X?
Search for the words and hashtags people in your niche actually use, and read the Latest tab, not Top.
X search operators make this faster. A few patterns that work:
| Search | Finds |
|---|---|
beekeeping (hive OR apiary) -giveaway |
Posts on the topic, minus promotional noise |
#beekeeping filter:media |
Posts with photos under the tag |
"my hive" lang:en |
First-person posts, often from hobbyists |
beekeeping min_replies:3 |
Posts that started a conversation |
Spend twenty minutes a day for a week. Each time you find someone who fits, note the handle. Our guide to X search operators for community feeds explains each operator in more detail. Once you have a handful of names and a tag in mind, the knot builder turns them into saved searches you can reopen every day.
How do you invite people without being spammy?
Reply to something specific they posted, say what the group is and ask whether they'd like to be on the List.
An example:
Loved the photo of the swarm catch. I'm starting a List of hobby beekeepers who share hive updates, with #HiveNotes for questions. Happy to add you if you'd like.
Ask first. Being added to a public List with a group name is visible to the person, and some people don't want to be labeled. Skip copy-paste messages and mass mentions, which look like spam to readers and can run into X's rules on unsolicited mentions.
What makes people come back after week one?
A regular, low-effort activity at a fixed time gives members a reason to open the List.
Pick one and run it every week:
- A weekly thread. "Show your hive this week," posted every Sunday morning.
- A hashtag chat. Five questions over an hour, same day and time. The chat planner shows the time in several time zones and drafts the question posts.
- A newcomer round. Once a week, quote-post two new members and say what they post about.
Consistency matters more than size. A thread that gets six replies every Sunday builds a group. A big launch post that gets forty likes and is never followed up does not.
How do you make the group findable?
Pin a post that names the group, links the List and gives the hashtag, and put the tag in your bio.
Newcomers will arrive through the hashtag long before anyone adds them to the List. Your pinned post is the front door: what the group is, how to join, the weekly ritual and the List link. Ask early members to pin the List as a tab on Home, which is the nearest thing to "joining" a group on X now. The guide to using X Lists as a community feed covers pinning and List limits.
When should you widen the List?
Widen it when the weekly activity reliably gets replies from people who aren't on the List yet.
That is the sign the group has a pull of its own. Add those people, check that the List still reads well, and consider splitting it into a core List and a wider one once it passes a few hundred accounts. Write down the few rules you enforce, such as what gets someone taken off the List, before you need them. Our moderation guide has a starting template.
Checklist
- Write the group's purpose in one sentence
- Find 20 people who post on the topic weekly
- Choose and search the hashtag
- Ask each person before adding them to the List
- Pin a post with the List link and the tag
- Run one weekly activity at a fixed time for eight weeks
Questions
Why start with 20 members and not 200?
A List of 20 people who post often reads like a conversation. A List of 200 strangers reads like a busy timeline nobody owns. Start small, get the habit going, then widen the List.
Should I invite people by direct message?
A public reply to something they posted is usually better. It shows you read their work, it's visible to others, and it doesn't land in a message request folder they may never check.
Do I need a big account to start a community?
No. What matters is that you post regularly in the group yourself and reply to members. Organizers with small accounts often do better, because members can see the group is about the topic.
How long before a new community feels alive?
Give it six to eight weeks of a regular weekly activity. Most groups feel quiet for the first month even when they are working.
