The company brain your agents read from.
You could build one by hand. The guides are everywhere. But the build was never the hard part. Patina is one home for your brand voice, personas, playbooks, and decisions, served to every agent you run and kept curated so it never goes stale.

The weekend build is the easy part
Every "build a company brain" guide gets you to the same place: documents in a store, retrieval wired up, a demo that works. Then the real job starts. Nobody prunes the pile. The positioning doc goes stale. You reverse a decision, the old one stays behind, and one agent picks up the new call while another picks up the old one. The output stops being consistent. And you're debugging your knowledge instead of using it. A company brain isn't a build. It's a discipline: something has to curate both the index and the content, or it's just a knowledge base. And knowledge bases go stale.
What lives in it
One home for the context that makes output yours:
- Brand voice: real examples plus the rules, so every draft sounds like you wrote it.
- Customer personas: your buyers in their own words.
- Playbooks: the workflows your best people figured out, written so agents can run them.
- Decisions: what's currently true, with reversals marked superseded so no agent acts on last month's call.
- Facts: the state of things your ops agents need to get right.
Every agent, one brain
You don't run one agent: you spin up many, for different tasks, in different tools. Patina serves the same curated context to all of them: a web app for your team, an API for your automations, and MCP for agents on surfaces like Claude that discover it themselves. One shared memory, not a private cache per agent, so what one agent learns, every agent inherits. Related reading: What is an agentic knowledge base?
Curated, not dumped
Patina is human-curated with a review workflow. New context gets proposed and reviewed before agents trust it. When an agent gets something wrong, you correct it once and the correction goes back into the brain, shared with every future run. That loop is what keeps the brain sharp while the wiki you built last quarter quietly rots.
Give your agents one home
It's not the model. It's what your agents know about your business.
