The Co-founder knows two kinds of things:
  • What you told it: your business profile and your documents. This always wins.
  • What it learned: facts and outcomes it picked up from your data and conversations, kept in the Vault.
When the two disagree, your version wins. The Co-founder can suggest a change to what you wrote, but never makes one on its own.

​
Business profile

Settings → Business holds two short profiles. Both reach every briefing. Two fields matter most:
  • Hard rules — never do these: “Never recommend removing the free tier.” The Co-founder won’t propose an action that breaks one.
  • Do not touch: “app name”, “MX pricing”. Stops it from suggesting changes to those.
You don’t start from a blank form. Shortly after you connect an app, the Co-founder drafts both profiles from your store listing, competitors, reviews and website. Hard rules and do-not-touch items only take effect once you confirm the draft. It never overwrites anything you wrote.

​
Documents

App Co-founder → Knowledge base is a library of Markdown documents: research, playbooks, notes for each part of your business. Start with business_context.md, the prose version of your profile: what you’re building, who it’s for, what you already tried. Unpinned documents are found and read when they’re relevant to the question or briefing. Each document keeps its revision history.

​
Keep Notion pages in sync

Under Settings → Automation → Company Brain sync, add a Notion page or a URL. The Co-founder keeps it ingested so your knowledge base stays current. Requires Notion connected in Integrations.

​
Suggestions

When the Co-founder notices something that doesn’t match what you wrote — your profile says “pre-launch” but you have 10,000 downloads — it suggests an edit. It keeps using your current version until you Apply or Reject, from the knowledge base or straight from the briefing email.

​
Memory vault

App Co-founder → Vault shows what the Co-founder learned: facts (stable things it observed, such as your brand voice) and episodes (each action it proposed and what came of it). It shows how they connect, and which ones support or contradict each other. You can also teach it in chat: “the spike last week was a YouTube sponsor” is remembered and used in later briefings.
