How it compares
A launch means nothing against no one. These are the launches it is actually comparable to, and where this one sits among them.

What this launch shows
Firecrawl posted this from an account with 89K followers and reached 3.2 times that many people. Accounts of that size usually reach 20.9 times their following.
This one did not get far past the people who already followed it. It ranks 204 of 264 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1324 of 1981.
Saves led. 919 people bookmarked it, 32.3 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: 110 replies, 79 quotes, 102 reposts.
The post opens with “Introducing Alexandria”, the same first word as 25% of launches in the directory. It carries a 1:23 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 37 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 651K views in the directory, and Friday is the strongest day at 880K.
How to announce a funding round covers this: the round is the news and the post has to turn it into customers and hires. 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 Developer Tool is on that vertical's directory page.
