What this launch shows
White Circle posted this from an account with 2K followers and reached 1106.4 times that many people. The usual multiple for under 5K followers is 161.4.
This one did 6.9 times that. It ranks 31 of 627 launches from accounts that size. Against every launch in the directory it sits at 3.4 times the median of 688K views.
Saves led. 2K people bookmarked it, 8.8 per 10,000 views against a directory median of 11.7. A bookmark is a plan to come back, and it tracks signups and demo requests more closely than a like does.
The rest: 166 replies, 126 quotes, 218 reposts. One bookmark for every 0.9 likes is a high ratio and usually means a product people intend to try.
The post opens with “Introducing Halo, the best framework for post-training of open-source models”, the same first word as 25% of launches in the directory. It carries a 42-second 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 38 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 developer marketing strategy: developers try before they read, so the post has to let them.
X analytics explained is the guide for it: what each of these numbers means, with benchmarks by account size. Every launch we track in Developer Tool is on that vertical's directory page.
