What this launch shows

The post went out from an account with 676 followers. It was seen 62.6 times over. For under 5K followers the usual multiple is 152.2, so the ranking model showed this to fewer strangers than it shows most launches.

It ranks 575 of 743 launches from accounts that size. Against every launch in the directory it is below the median of 603K views, at rank 1993 of 2314.

Replies led. 37 of them, 8.7 per 10,000 views against a median of 2.5.

The post started a conversation, and the ranking model pays for conversation with reach in the hours after. Bookmarks came in at 80, reposts at 17.

It starts “Introducing Cortex Harness, a platform for running AI models on real robots with remote human guidance”, the same first word as 25% of launches in the directory.

It carries a 1:00 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 45 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 Tuesday. Launches posted on a Tuesday have a median of 595K views in the directory, and Friday is the strongest day at 647K.

Launching a product on X from a small account covers this: an account with 676 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.
