Become a design partner

Δ DESIGN PARTNER PHASE

We are building this with a few teams. Be one.

ChangeBox is not open for self-serve sign-up. During the design partner phase there is one plan, one price, and one door: pay, sign in with the same email, and you are in with everything turned on.

DESIGN PARTNER

$500/month

Cancel any month. Your Cursor usage is billed by Cursor, not by us.

Stripe handles the card. When the payment goes through, the organization is created and a sign-in link is one click away.

WHAT YOU GET

Everything, turned on.

Every door
The Δ widget with the intake assistant, the telemetry door, MCP and the API for your agents.
Agents that ship
Cursor Cloud Agents on your repositories, under your execution policy, with independent review on every PR.
The Verifier
A browser agent that opens the live page after a deploy and checks the acceptance criteria before anyone is asked to.
Slack and Teams
One card per change, a releases stream, a sign-off log. Scaffolded for you, routed per app.
Ten apps, twenty-five people
Room for every product line and the people who run it. Roles per org and per app.
A direct line
You talk to the people building it. What you need next week is on the board this week.

THE DEAL

Four things we ask.

  1. 01You use it on a real product with real reporters, not a sandbox.
  2. 02You tell us what is wrong, bluntly, roughly weekly. A Slack Connect channel or a call, your choice.
  3. 03You let us quote the outcomes, never the specifics, once you are happy.
  4. 04You keep the price for as long as you stay.

THE FIRST HOUR

Set up before lunch.

One script tag for the widget. One environment variable if you already emit OpenTelemetry. One login in your product for the Verifier. The setup guide has the exact snippets for each stack, and a person answers when something does not fit.
