X lists for founders are a simple way to follow small groups of accounts, such as buyers, peers and creators, in a separate timeline from the main feed. Keep a few private lists, check them daily for posts worth replying to and use them to prepare launch outreach. They give you control the algorithm does not.
Most founders who treat X as a main channel hit the same problem. The For you feed is busy, the Following feed fills up and the accounts that matter most, the people who might buy, partner or share, get lost among everything else. Lists solve that by giving each group its own timeline you can check on purpose.
This play covers which lists to build, how to set them up and how to use them every day without them becoming another chore. Facts about how lists work come from X help, “How to use X Lists” (archived January 2026).
How X lists work
A list is a group of accounts you choose. Viewing the list shows a timeline with posts from only those accounts. According to X help:
- You can create your own lists and follow lists made by others.
- You do not need to follow an account to add it to a list.
- You can follow someone else’s list without following each account on it.
- New lists are public by default, which means anyone can follow them. You can switch a list to private so only you can see it.
- List names can be up to 25 characters and cannot begin with a number.
- You can pin lists so they appear next to the For you and Following timelines.
- You can see which lists you have been added to, and to remove yourself from a list you have to block its creator.
Because members can see the lists they are on, think about how a public list name reads to the people on it. A private list avoids that question entirely.
The lists worth building
Start with a few lists, each with one purpose. The right set depends on what you sell, but these cover most AI startups.
| List | Who goes on it | What you use it for |
|---|---|---|
| Buyers and users | Current users, people who signed up, people in your target role | Replies, feedback, spotting use cases |
| Peers | Founders at a similar stage or in nearby categories | Sharing notes, mutual support, cross posts |
| Creators | Accounts your audience follows and trusts | Relationship building before any ask |
| Press and analysts | Writers who cover your space | Knowing what they care about before a pitch |
| Competitors and adjacent tools | Companies and their founders | Understanding positioning and timing |
Keep each list small enough to read in a few minutes. A list with hundreds of accounts quickly turns into another noisy feed.
Setting up lists the right way
A few setup choices make lists easier to use for months.
- Make working lists private. Buyer, competitor and press lists are research tools, not public statements. Switch them to private when you create them.
- Name lists for their job. Short names like “Users” or “Creators” are easier to scan than clever ones, and they fit the 25 character limit.
- Pin the lists you use daily. Pinned lists sit next to your main timelines, so checking them becomes part of opening the app.
- Add people as you meet them. When someone replies to you, signs up or posts about your problem space, add them to the right list right away.
Using lists every day
Lists only help if they shape what you do. A light routine is enough.
Each day, open the buyers list and the creators list and look for two or three posts where you can add something real: an answer, a relevant example, a useful question. Thoughtful replies to the right accounts often do more for a small account than original posts, and the twitter reply strategy play covers how to write them.
Once a week, scan the peers and competitors lists. Note what people in your space are launching, which posts get replies and which questions keep coming up. Those notes feed your own content and positioning.
Before you write a post, check the buyers list for the words people use to describe the problem. Writing in their language helps the post land with the people you want to reach.
Using lists for launch preparation
Lists are especially useful in the weeks before a launch.
Build a launch list of people who have engaged with you before: users who replied, peers who shared your posts, creators who mentioned the problem you solve. In the days before launch, check that list for who is active and what they are talking about. On launch day, it gives you a quick view of who to thank, reply to or message directly.
This does not replace direct outreach to your users. A message to someone who asked to hear from you still matters more than a reply. But a launch list makes the outreach easier to organise and helps you notice when someone you know posts about the launch. If you are building in public on the way to launch, the build in public on X play explains how to use that time well.
Public lists as a resource
Most of your lists should stay private, but a public list can be useful when the list itself helps others. A carefully chosen list of builders, tools or educators in your niche can be shared as a resource, and people may follow it.
If you publish one, keep it accurate, keep it current and only include accounts that fit. Remember that members can see they are on it, so the name and description should be ones they would be happy to see.
Lists and communities
Lists and X Communities solve different problems. A list is your private view of a group of accounts. A Community is a shared space where members post to each other. Many founders use both: lists to follow buyers and creators, and a Community for deeper conversation. The X communities play explains when a Community is worth starting.
Keeping lists useful over time
Lists go stale. People stop posting, change roles or drift away from your space. Once a month, remove accounts that no longer fit and add new ones you have met. If a list keeps growing, split it into two with clearer purposes.
If you notice you have not opened a list in weeks, either delete it or decide what it is for. A list you never check is just clutter.
Common mistakes with X lists
- Leaving working lists public when they are meant for research.
- Adding too many accounts, which turns a list into another noisy feed.
- Building lists and never pinning them, so they never get checked.
- Treating lists as a replacement for direct outreach to users.
- Naming public lists in ways members would not like to see next to their name.
