You own it

Plain files. Yours forever.

The memory is a vault of linked notes (the same format as Obsidian) on your own server. Models come and go every few months; your company’s memory doesn’t go with them.

  • Company and personal vaults kept separate
  • Every note links to people, decisions and documents
  • Synced to the server the agents run on
  • Backed up, versioned, exportable

What the system did

Nothing yet. Send a message on the phone and the actions show up here as they happen.

Day one

It starts with 30 questions.

Before we connect a single tool, we interview the founder. The answers become the foundation every agent works from.

  1. 01What are the three numbers you look at first every morning?
  2. 02Which decisions can a manager make without you, and up to what amount?
  3. 03Who are your 10 most important clients, and what does each one care about?
  4. 04What does a perfect week look like for the business?
  5. 05Which tasks do you still do that you wish someone else did?
  6. 06What mistakes has the business made that must never happen again?
  7. 07How do you price a job, and when do you give a discount?
  8. 08What tone do you use with clients on WhatsApp versus email?
  9. + 22 more, tailored to your industry

Why not just ChatGPT?
