The first line is “Today we’re launching Cardinal Square, an AI-native tutoring school”, a first-person opening that the founder-account launches in the directory use most. It carries a 1:18 video against a directory median of 66 seconds. Videos between 30 and 90 seconds have a median of 537K views in the directory.
The copy runs 13 words, shorter than a launch post here, where the median is 41. There is a link in the body, which costs a post some reach and buys it a place to send people.
It went out on a Friday. Launches posted on a Friday have a median of 647K views in the directory, which makes it the strongest day.
Launching a product on X from a small account covers this: an account with 755 followers has to earn every view from outside its own following.
For the next one, read attributing signups to a launch: a save rate this high is the number to follow into the product. Giving people something to reply to is the guide for it: the conversation is what carried this one.
