01 — The company
Every network starts the same way. Hand over your name, an email, a phone number, and then you may join. That record follows you for years, through every breach and every buyer of it. We thought the trade was wrong, so we spent our time on a different question: could a network know you are a real person without ever learning who you are? It can. Face ID is the door. Behind it, there’s no record of who you are. No name, no contact detail, no face on our side. You connect. You stay yourself. What you share from there is your call.
Before
With PRUF
The first place to try it is a social network we built on it, so anyone can watch it work. Zero PII, end-to-end encrypted, closed to bots, and a walled garden of photos people took themselves. For anyone who has had enough of AI content.

03 — Next · Planned
Websites, AI agents, anything that needs a human at the door and nothing else about them. More when it ships.
