Train your agents on real CEO brains.

Cognition Personas is a marketplace of digital brain models built from real founders and operators — their decisions, reasoning patterns, knowledge graphs, and how they think under pressure. Query a persona via API to test whether your agent actually serves a real human user, not a hypothetical one.

What you get

Three primitives. One marketplace.

Query a brain via API

POST a context + question to /api/v1/personas/query. Get back what the persona would say, what they'd remember, and the decay/confidence on each fact. Stable schema, JSON in / JSON out.

Test agents against real personas

Wire your agent's responses through a battery of real CEO brains. Where does it serve? Where does it miss? Get fit scores per persona-segment, not just toy benchmarks.

Train on a thinking model, not a dataset

A persona isn't a static text dump. It's an evolving model of how a specific person decides, what they forget, what they re-litigate. Use it as the ground truth your agent has to satisfy.

We're a research lab. CLO is what we ship today. Personas is what we're building next — the substrate underneath both is a memory model for organizations and the people inside them.
