Matt Zimak Case studies A company brain

A company brain, updated by every meeting.

Everything a company knows, in one GitHub repo that people and AI agents read alike: strategy, decisions, customers, suppliers, people. After every meeting the new facts go in with their source, and a change to strategy, decisions or finance waits for a person to approve it in Slack. Fed by every meeting of a family business group since July 2026; four more companies run on the same structure.

Who is this for?

What problem does it solve?

What a company knows lives in meetings, chats and a few people's heads. A new hire, an adviser or an AI agent starts from zero, and a decision made in March gets argued again in June. A wiki helps until nobody updates it.

What it does.

One repo per company
Strategy, products, brand, goals, customers, suppliers, people and decisions, one file per thing, in plain text that people and agents read alike.
Fed by every meeting
Fireflies records the meeting. n8n files the transcript in the repo and pulls out the facts, each with the sentence it came from.
A curator every night
A Claude agent folds the new facts into the right files: dated timeline entries, meeting notes, new contacts and suppliers as drafts, each citing its meeting. Once a week it writes a short brief per company.
A person for what matters
A change to strategy, a decision, the goals or finance becomes a pull request and a card in Slack, in the team's language, with Approve and Reject. Approve merges it; nothing core changes without it.
Any agent
Ask it in a Claude chat, edit it with Claude Code, or point Cursor, Codex or any other agent at the repo. It is plain files in Git, so no tool owns it.

How it was built.

  1. May to June 2026

    The first brains, one GitHub repo per company on one structure: a design studio group, my own three companies, then a family business group.

  2. 7 July

    Meetings start feeding it: the n8n fact tap, the nightly curator and the approval card in Slack.

  3. August

    A weekly check for broken links, duplicates and contradictions.

  4. September

    The meeting loop published as an open-source template, next to the repo template.

  5. By October

    149 meetings folded in, a weekly brief per company, and the transcripts searchable in the CEO's terminal.

The rules it runs by.

Every fact cites its meeting
No source, no write.
Timelines only grow
An entry is never edited or deleted. A correction is a new dated entry.
Decisions stay as decided
A merged decision record is never rewritten, not even through a pull request.
Nothing invented
A missing number, date or name stays missing. An uncertain fact is flagged and goes to a person.
Private stays private
Pay, health and family topics from a meeting are noted as a sensitive topic, never quoted.
Checked every week
A separate pass looks for broken links, duplicates and contradictions.

What the owners have now.

One place for what is true
Timelines, contacts, suppliers and meeting notes per company, current to last night's meetings.
Context for every agent
A Claude chat, Claude Code or any other agent starts from the company's real facts.
A weekly brief
Each company gets a short summary of its week, written from its meetings.
Control
Core files change only on Approve. Everything else carries its source and can be undone in Git.

The same brain, five times.

The same structure runs for a design studio group and for my own three companies: Agentmatik, Deep Noise and Museverse. The repo template and the meeting loop are open source on GitHub, as template-intelligence and brain-curation-loop. The meeting transcripts also feed the CEO's terminal.

Fifteen minutes on what your company knows, where it lives today, and which meetings should feed it first.
