What this launch shows
Rex posted this from an account with 233 followers and reached 193.2 times that many people. Accounts of that size usually reach 161.4 times their following, so this is in the normal range.

A bookmark is a plan to come back, and it tracks signups and demo requests more closely than a like does. The rest: 32 replies, 2 quotes, 8 reposts.
The post opens with “Today we're launching Rex (YC S26)”, a first-person opening that the founder-account launches in the directory use most. It carries a 1:17 video against a directory median of 65 seconds. Videos between 30 and 90 seconds have a median of 603K views in the directory.
The copy runs 39 words, about the usual length for 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 Monday. Launches posted on a Monday have a median of 618K views in the directory, and Friday is the strongest day at 880K.
Launching a product on X from a small account covers this: an account with 233 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. Every launch we track in Enterprise AI is on that vertical's directory page.
