User-owned state
Every piece of context, every skill, every memory belongs to the person who created it. We are custodians, not owners.
ABOUT
Building personal intelligence.
We are a small, focused team building a new kind of AI product -- one designed to make people more capable over time, not more dependent.
Most AI companies are racing to build the smartest model. We are building the infrastructure for people to own their own intelligence -- context that persists, skills that compound, and coordination that multiplies.
Our values.
Compound over time
We build features that get more valuable the longer someone uses them. If something does not compound, it does not ship.
Consent before action
Your agent only acts within boundaries you define. Autonomy is earned through trust, not granted by default.
Privacy as architecture
Privacy is not a feature you toggle. It is built into the system from the ground up. Your data is never used to train models.
Small groups matter
We optimize for the family, the small team, the creative partnership -- groups too small for enterprise software but too important to ignore.
Clarity over cleverness
We choose the clear explanation over the impressive demo. We build tools that make people more capable, not more impressed.
The thesis.
In a world where every app is reachable by language, assistant features commoditize overnight. The only thing that compounds is what a person owns: their memory, their standards, their network.
Joined is built on the conviction that durable, user-owned state is the defensible moat in personal AI. Not the model. Not the interface. The accumulated intelligence of a human life.
What we are building.
- Persistent memory that carries your life forward
- Skill engine that turns corrections into reusable behavior
- Coalition coordination for families and small teams
- Escalating autonomy from suggest to self-operate
- Cross-platform presence on iOS, Android, and web
