How it works

Fifteen minutes. Three moves.

01 · ANSWER

Reply to these posts now

We scan X for posts that are about to take off in your niche: founders, dev tools, AI, marketing. You get 5–8 posts with a one-line brief on what to say, ranked by how much reach a reply gets right now. No timeline scrolling.

02 · REPRODUCE

Don't miss the trend

When a format goes viral you get it within hours: the template, what the top posts did differently, and the mistakes that kill reach. One right post at the right time is worth 300–1,500 followers.

03 · WRITE

Post this today

One post idea per day, picked from what's working this week, with the hook and the format. You write it in your words, press post, close X.

The data

One 12-word post. 2.4 million views. We measured what happened next.

On 12 September a German solo founder posted "I'm 38. Solo founder from Germany. Looking to connect with more builders & indie hackers!" We tracked 535 copies over the following five days.

2.39M
views on the original post. Its author gained 500 followers in a day.
1,764
median views for a copy. Most accounts that copied it had under 2,000 followers.
2.5K
followers in 5 hours for the best copy, a marketer in Barcelona with a photo.
5.6×
more views for women posting the same template. Photo, city and a real detail beat the bare template.

"This tweet got me 2.5K followers in 5 hours. Make it make sense."

Questions

Before you ask

Is this automation? Will it post for me?

No. Nothing touches your account. You get a list and a brief; you write the reply. Automated replies get accounts suspended and everyone can tell they're bots. The 15 minutes are yours.

Why replies and not my own posts?

A new account's posts reach its followers, which is nobody. A reply under a post with 200k views is shown to people already reading. In our dataset the reply-driven posts got 75 replies per 100 likes; that's where the follows come from.

What's in the daily playbook exactly?

Three parts. Posts to answer: 5 to 8, each with who posted, why it will grow, a one-line brief for your reply, and how long the window is open. Trends: any format taking off, with the template and how to reproduce it. Post today: one idea with hook and format. Updated every morning European time and again at noon, so open it whenever suits you.

I'm not a founder. Is it for me?

Yes if you sell to founders, developers or marketers, or want to be seen by them. Designers, devrel, agency owners and freelancers use the same lists.

How does the €499 plan work?

Week one: a 45-minute voice interview and a look at your product. Then you get 30 posts for the month in a shared doc, in batches, edited with you. You post them or schedule them. We track what worked and adjust next month.

Who's behind it
Kate

Kate, marketer and founder

I grew my own X account with replies while running a company and having no time for X. I built the finder that spots posts before they take off for myself, then friends asked for the list. The trend data on this site comes from that same tooling. Say hi: @chiefkittenme.
