On X, the algorithm rewards conversation. Posts get reach when other accounts reply to them, and when you reply to other accounts, theirs do too. So the right way to grow is to climb a ladder of replies, not to publish more.
Here's the ladder, from the bottom up.
Today: reply to people slightly bigger than you
Find five accounts that have one zero more followers than you do. If you have 100, that's people with 1,000. If you have 1,000, that's people with 10,000.
Their posts get a lot of replies but not so many that yours gets buried. Your reply will be seen by people who don't know you yet. Some of them will follow you. This is the rung that grows your account fastest.
Set a reminder. Five replies before noon, every day. The whole thing should take fifteen minutes.
This week: reply to peers
Pick five accounts at roughly your size who post about the same thing you do. Reply to them like a friend. Make a joke. Add a fact. Disagree politely.
These are the people who will quote-post your stuff later. Treating them well now is how that happens. It's not networking, it's just being around.
This month: reply to the giants
Once a week, reply to someone with a hundred times your followers. Don't try to be clever. Add the one detail they left out. The reply gets seen by their audience for an hour or two and that's a real spike.
Don't do this every day. Reply guys get muted. Doing it once a week and only when you have something to add keeps you welcome.
What to actually say
Replies that work are short, specific, and add something. They're not "great post" or "this." They're "this is also why X happens, in case anyone's wondering."
If your reply could be a tweet on its own, it's a good reply. If it could only exist as a reply, it's not.
Why this beats posting more
Most founders try to grow by posting more. Posting into a small audience just trains you to write to a small audience. Replying puts you in front of bigger ones. Then when you post, more of them are watching.
Climb the ladder. Then post.
