What this launch shows
From an account with 15K followers, this reached 30.7 times the account's own following. The median for 5K to 25K followers is 50.8 times, so this one stayed closer to home than most.
It ranks 274 of 479 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1201 of 1981.
Saves led. 7K people bookmarked it, 152.3 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: 193 replies, 54 quotes, 327 reposts. One bookmark for every 0.7 likes is a high ratio and usually means a product people intend to try.
The first line is “Introducing jevgrep - a research agent CLI powered by jev from @typesafeai that reduces your coding agent cost…”, the same first word as 25% of launches in the directory.
It carries a 31-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 44 words, about the usual length for a launch post here, where the median is 41. The body carries a link, so the post had somewhere to send the reader and paid a little reach for it.
It went out on a Sunday. Launches posted on a Sunday have a median of 526K views in the directory, and Friday is the strongest day at 880K.
Attributing signups to a launch covers this: a save rate this high is the number to follow into the product. For the next one, read giving people something to reply to: the conversation is what carried this one.
Developer marketing strategy is the guide for it: developers try before they read, so the post has to let them. Every launch we track in Developer Tool is on that vertical's directory page.
