The science behind your real circle.
In the 1990s, British anthropologist Robin Dunbar discovered something fascinating: the human brain can only maintain about 150 stable relationships. Beyond that, connections become superficial.
Social media ignored this. They optimized for billions of "connections" — and gave us loneliness, comparison, and algorithmic noise instead of real community.
D150 is built around the science. We cap your network at 150 real, verified humans. Every post you see is from someone you actually know. Every interaction is meaningful. That's it.
