GTM Vault · The Stack Index

Seven layers take instrumentation. One never will.

The Stack Index is every GTM tool operators named on GTM Vault, placed on the layer of revenue architecture it serves. Sequencing, the decision about what gets built first, takes no instrumentation, because nobody sells it.

01Find the layer where your revenue system is breaking. Run the audit, eight questions.

02See which tools operators run there, and what each one did.

03Get the build order for your company in Build Your Stack.

The Eight Layers, and what reports to each

Build order runs from the ground up. Hover or tap a layer to see what reports to it and which tools operators run there. The dashed row is the argument.

What it shows. Instrumentation piles into Motion and Distribution, then the AI Layer. Pricing and Metrics are nearly bare. Sequencing is empty by definition, and every layer above it is built in the order it decides.

Sequencing

What gets built and scaled, in what order.

Nothing reports here, and nothing will.

Every other layer can be instrumented because it has a function a product can perform. Sequencing is the decision about which of those functions to build first. It is made by a person with the whole system in view, and it is the reason two companies with identical stacks get opposite results.

A vendor that claims to handle sequencing is describing workflow order inside its own tool. That is orchestration, and it reports to Functional Coherence.

03

Pricing

Not a number. A structural decision that reshapes qualification, motion and margin.
