The hard problem isn’t a bigger model. It’s a system that becomes one person.
We’re a small team solving one of the most interesting problems in AI: making intelligence personal, durable, and owned by the people who create it.
Every major AI lab is building general intelligence. We’re building a personal agent you actually own — designed around durable, user-owned state, not transient conversations.
No one has built a system that compounds into a single person. The architecture is unsolved — that’s the job, and it’s a better one than making a model 3% smarter.
