It starts “Today, we’re introducing Mercury 2.5, the most capable diffusion LLM on the market”, a first-person opening that the founder-account launches in the directory use most. It carries a 43-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 Tuesday. Launches posted on a Tuesday have a median of 651K 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.
