Why 150
The number your brain already keeps.
Anthropologist Robin Dunbar found that people tend to keep about 150 meaningful relationships, in layers of roughly 5, 15, 50 and 150. 100fifty is built around those layers instead of fighting them.
Who you'd invite to a big party, and who'd be glad to see you there.
How it works
Social, minus the parts that made it worse.
A feed that ends
Posts arrive in the order they were shared. Catch up on everyone, then get on with your day.

My group chats had quietly become the only place my real friends were, and they were drowning in everything else.
Dunbar put the number of people we can truly keep up with at about 150. 100fifty is a home for exactly those people, and nothing more.
FAQ
Good questions.
Why only 150 friends?
Because that's roughly how many relationships people can keep up with. A smaller network means a feed of people you actually care about, and fewer reasons to perform for an audience.
What happens when I reach 150?
To add someone new you either make room or keep them on a waiting list. Nobody is told when they're moved; it's your circle.
How does 100fifty make money?
From members, never from advertisers.
Who can see my posts?
Only the circle you share each post with. There are no public profiles, and nothing you post is used to target you or sold to anyone.
Can I leave and take my stuff?
Yes. Export everything as a download, or delete your account and all your posts in one step.
