Our company brain

Every meeting and email becomes a reviewed to-⁠do, decision or dollar amount, in one record we own and every AI tool we use works from.

  1. Meetings and email

    Recordings, transcripts and email threads, as they happen.

  2. An agent reads them

    It proposes the to-⁠dos, decisions, facts and money it finds, quoting the words it found them in.

  3. One of us approves

    Nothing about money, people or decisions is filed without a yes, and every change can be undone.

  4. Our company brain

    One record we own. The AI tools we work in, our phones and our calendars all read from it.

How a meeting becomes something we can act on, with a person signing off before anything that matters is filed.

The problem

The problem

Two founders, a growing list of clients, and the facts that matter spread across recordings, inboxes and memory. What did we promise, what’s owed, who’s waiting on whom: we were answering from memory, and memory is where promises go missing.

What we built

What we built

A record of our whole company, and an agent that keeps it current. Recordings, transcripts and email go in, and nothing that matters is filed until one of us approves it.

  • A Today screen: what’s overdue, what’s waiting on us and what money is open.
  • A Review queue: every proposal beside the words it came from. Approve, edit or reject.
  • An agent that files the routine and asks before anything that matters.
  • Every change logged under the person who made it, with an Undo.
  • The AI tools we use read it and update it, on our say-⁠so.
  • An iPhone app that records a meeting straight in, and every dated promise lands in our calendars.

Where it stands

Where it stands

Live and in daily use since September 2026. It’s how we run Cornerstone, and it’s the same kind of brain we build for clients: one record they own, read by every tool they use, with a person signing off on anything that matters.
