What this launch shows

From an account with 2K followers, this reached 37.3 times the account's own following. The median for under 5K followers is 161.4 times, so this one stayed closer to home than most.

It ranks 431 of 627 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1637 of 1981.

Replies led. 60 of them, 8.1 per 10,000 views against a median of 2.3.

The post started a conversation, and the ranking model pays for conversation with reach in the hours after. Bookmarks came in at 204, reposts at 27.

The first line is “We’re excited to launch Instance – a success detector for robot rollouts”, a first-person opening that the founder-account launches in the directory use most. It carries a 1:13 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 49 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 2K 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 Robotics is on that vertical's directory page.
