Our company brain, live and growing.
Sentry AI runs its own business on its own company brain before we build one for anyone else. This is what it holds, how it is organised and how it grows, counted on 18 October 2026.
The short answer
On 18 October 2026, Sentry AI's company brain held 1,342 linked pages across 17 top-level sections, among them 26 workflow pages, 6 department pages, 108 people pages and 216 meeting pages. Every AI agent that works for the business reads it before acting. It grows through the work: each session banks what it learned, meetings and corrections are written in, and a daily check flags pages that have gone stale or contradict each other.
What it holds
Counted from the brain itself on 18 October 2026. We update these numbers with the date we counted them, rather than quoting a figure once and leaving it.

Departments
| Section | Pages | What is in it |
|---|---|---|
| Client work | 419 | One folder per engagement: a one-minute brief, the full history, research and meeting notes. |
| Knowledge | 390 | How we work: delivery doctrine, architecture, marketing, legal, finance and the rules we have settled. |
| Meetings | 216 | Notes from every call worth keeping, linked to the people and clients in them. |
| People | 108 | Who someone is, how we know them and what we have done together. |
| Company | 37 | Sentry AI's own profile, goals and standing context. |
| Workflows | 26 | Each job we run, how often, which tools it touches and which skill does it. |
| Systems | 8 | The tools the business runs on and what each one is the source of truth for. |
| Departments | 6 | Engineering, Delivery and Knowledge among them, each listing its workflows. |
The rest of the 1,342 is archive, an inbox for pages waiting to be filed, daily digests and a few smaller sections. Client pages are kept per engagement and never cross into another client's work.
Organised by department
The brain is organised the way the business works. Each of the six department pages, Engineering, Delivery and Knowledge among them, lists the workflows that department runs and how often: daily, weekly, monthly or when needed. Each workflow page names the tools it touches and the skill that does the job, and links to the decisions and people behind it.
That is the same structure we build for a client, which is the point of running our own business on it first. When we explain what a company brain is, we are describing this one.
How it grows, week by week
Nobody sits down to document the business. The brain grows because the work writes into it.
Every working session banks what it learned
When an agent finishes a piece of work, the durable part, a fact, a decision, a correction, a change to a client's situation, is written into the brain before the session ends. Nothing depends on someone remembering to write it up later.
Meetings are written up and linked
Calls worth keeping become meeting pages, linked to the people in them and the client or project they were about. The next agent to work on that client reads the meeting before it starts.
Corrections become rules
When our founder corrects an agent, the correction is written down in his words as a rule, so the next answer is different. This is how the brain gets more right, not just bigger.
A daily check keeps it honest
Every day a review pass looks for pages that have gone stale, pages nothing links to, and pages that contradict each other, and proposes fixes for a person to accept or reject.
Every agent reads the same copy
The brain syncs on a fixed schedule every six hours, so every agent, whatever it is working on, reads the same current pages.
Frequently asked questions
How big is Sentry AI's company brain?
On 18 October 2026 it held 1,342 pages across 17 top-level sections, including 26 workflow pages, 6 department pages, 108 people pages and 216 meeting pages.
Who reads it?
Every AI agent that works for Sentry AI reads it before it acts, and so does our founder. When an agent is asked how something is done here, it looks it up rather than guessing.
How does it grow?
Through the work. Each working session ends by banking what it learned. Meetings are written up and linked to the people and clients in them. Corrections are written down as rules. A daily check flags pages that have gone stale or contradict each other, and a person settles them.
Is a client's brain the same as yours?
The structure is the same: departments, workflows, systems, decisions and people, linked to each other. The content is the client's own, it is kept separate from everyone else's, and it belongs to the client.
Why show the count?
Because it is the one claim about a company brain anyone can check. We update the count on this page with the date we counted it, rather than quoting a number once and leaving it.
