How Physical Superintelligence announced a $58M raise on X

What this launch shows

Physical Superintelligence posted this from an account with 69K followers and reached 9 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 169 of 264 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1042 of 1981.

Replies led. 265 of them, 4.3 per 10,000 views against a median of 2.3. The post started a conversation, and the ranking model pays for conversation with reach in the hours after.

Bookmarks came in at 604, reposts at 277. One bookmark for every 4.4 likes is a low ratio for a launch, and reads as entertainment more than intent.

The post opens with “I'm delighted to share that Physical Superintelligence PBC (PSI), which I co-founded with @matthew_pines and @AKlokus, has raised…”, a first-person opening that the founder-account launches in the directory use most.

It carries a 1:35 video against a directory median of 65 seconds. Videos over 90 seconds have a median of 651K views in the directory.

The copy runs 40 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.

How to announce a funding round covers this: the round is the news and the post has to turn it into customers and hires.
