xGo

The co-build method, as software. A Claude Code plugin that takes a product from raw idea to paying customers, with a strong bias toward validating before building.

Two rules
In progress

Don't build a product until someone pays.

The minimum launch is usually not code.

Every product runs through stages.

Each stage has a milestone, a measure, and a trigger that unlocks the next one.

00

Vision

Define the problem, the signal it exists, and who it's for.

01

Launch minimum

The smallest thing in front of real people. Usually not code.

02

First paid customer

Prove someone will pay. The best validation there is.

03

Validate

Repeat it. Find the pattern.

04

Build to scale

Only now automate what you validated by hand.

05

Grow

Acquire customers efficiently.

We use it on every co-build first.

xGo runs inside our own co-builds before anyone else gets it. When a piece is ready, we share it on Signal.
