One sealed brain per client
The company brain built for agencies.
Every client gets its own brain: separate storage, its own encryption key and its own agent in Slack. The agent writes in the client's voice, and every draft waits for a person to approve it. Nothing goes out on its own.
Design-partner stage · Dedicated storage in AWS Frankfurt · Claude, or your client's choice of model
How it works
Ask. It drafts. A person decides.
Your account managers work in Slack. Nobody needs a terminal.
- 01
Ask in Slack
Each client's brain has its own Slack app. Mention it and ask for what you need.
- 02
It drafts, and flags what it can't back up
Every draft comes with its angle, its sources and the gaps it found. Nothing is invented to fill them.
- 03One-click approval in development
A person decides
Every draft waits in the queue with a fingerprint of its exact bytes. The agent can't post, and tools stay read-only until you say so.
Built for agencies
You hold other companies' brands. Your AI should act like it.
Every request lands in its own client's brain, and nothing crosses between them.
Separate storage bucket and encryption key per client, in AWS Frankfurt (eu-central-1). Send your client our security page →
Enforced, not asked
We don't ask the model to behave. It never sees the key.
Most AI tools ask the model to follow the rules. We limit what the agent can reach instead.
How we enforce each one →
- D-1Enforced
A jailbroken agent still can't phone home.
- D-2Enforced
Tool tokens never enter the model's context.
- D-3In development
Nothing publishes without a signed approval.
- D-4Enforced
One client's credentials can't open another's brain.
What's in Brainstead
Nine parts. One rule: clients stay apart, and a person decides.
Some of it runs today. The rest is in development for public launch.

Use a client's brain from your other AI tools, with the same rules.
Run end to end on a real client's brain: an on-brand draft from Slack, tools that stayed read-only, and a write switch that was refused, allowed and refused again.

We're working with a small group of agencies as design partners. Priced per client brain, not per seat.
Is it ready?
It has run a real client's brain end to end. It's at design-partner stage: signed approvals, roles and single sign-on are the next builds.
Where does our data live?
In AWS Frankfurt (eu-central-1), on dedicated infrastructure: each client gets its own storage bucket and encryption key.
Which AI model does it use?
Claude by default, through Anthropic's API, or another frontier model your client chooses, on their own subscription or API key.
Thanks. We've got your request.
