Backpack.The world model behind your business.

Backpack organizes your business's data from your team's messages. Your people, your apps and your AI agents work from it with better information to make better decisions.

The world model at work

What your team already writes becomes your world model.

What changes is who does the filing. Your team writes one line; AI finds the right records, changes them and keeps the history, and an agent brings anything it's not sure about to a person.

How it works

Send it in. Backpack files it.
A person checks it.

The AI makes mistakes, so it asks when it doesn't know. A wrong change is put right in one place, and the old value stays in the history.

Send. A message in Claude, Slack, WhatsApp or your custom app. Voice notes, photos and meeting notes work too. No forms.

File. It finds the cooling system, the cold room and the contractor, adds the reading to the system's history as an alarm, and sets a task for the contractor today.

Check. An agent reviews recent changes in bulk and brings anything doubtful to a person.

An example

Everything in your business has a page.

Every system, site, supplier and customer has its own page with its whole story: each reading, visit, cost and change, and the message behind it. Below is the cooling system of a warehouse at Dune Logistics, a made-up company. A real page, from our farm, is on the Living Lab.

Backpack runs on Backpack

We build Backpack with Backpack.

Our requirements and tasks live in Backpack, each linked to the world model of our own business, so the plan and the work stay connected. Meetings become requirements and tasks, and every code push moves the plan so it stays current. Anyone, a person or an agent, can see why it changed: 4,478 changes since August 2026.

  1. 1Agree

    What we agree in a meeting becomes requirements and tasks, straight from the transcript.

  2. 2Build

    Developers and their AI agents build from the latest requirements and tasks.

  3. 3Ship

    The AI reads each code push, closes its task and updates its requirement.

  4. 4Run

    People run the new process on real work and test it.

  5. 5Learn

    What they find becomes the next requirement.

Then back to Agree. Every change keeps its reason.

Your plan keeps up with the work.

Finish something, and Backpack moves the goal it belongs to. This is the goal for this website, moved by the code that built it.

For your apps and agents

How to work with Backpack.

Backpack is the operating system your business runs on. Your business uses apps and agents: ready-made ones from Backpack, your own, or both. They all run on the same foundation: your world model.

Keep your own screens and your own code. Your app and your AI agents reach the world model through MCP and an API, with a key you make for your world: search it, ask it questions, send it what happened. Backpack keeps the model current and the reason for every change; you build whatever you want on top.

It always knows it's really you: people sign in with Google, your app uses a key you made, and in a chat group it knows who sent each message.

Set up for you

We set it up for how you work.

On a call, describe your business and watch its world model take shape. Then we set it up with you: your world, your WhatsApp group or Slack, your team and a first process. We run it next to what you use today until you trust it. That's how we moved the farm.
