GTM Studio is a desktop GTM workbook - describe the target list you want in plain language and it fills in column by column, saving locally as it goes. Any column can still be a value, a sandboxed function, an LLM prompt, or a live enrichment call - drop into an embedded Claude Code terminal the moment a cell needs judgment instead of a formula.
A normal spreadsheet only holds what you type into it. GTM Studio is a GTM workbook - any column can be a value, a sandboxed function, an LLM prompt, or a live enrichment call, and the whole sheet still runs sourcing through launch underneath.
Input, sandboxed function, LLM prompt, or live enrichment call - one row, four ways to compute a cell.
Every sheet still runs sourcing, enrich, segment, copy, and launch. Not a slide - a pipeline that actually executes.
An embedded Claude Code terminal sits inside the sheet, so you never leave the workbook to think through a hard cell.
legion gtm-studio on your PATH is the real agent seam - no hidden API to reverse-engineer, no black box in between.
Grounded in the GTM MCP - 1,626 campaigns of proven pattern, so its judgment starts where a decade of outcomes left off.
Nothing runs in a black box. Spend and progress surface live, so you know what a sheet cost before it's done.
Every GTM Studio sheet is a live workbook. Each column fills as it runs, and the result saves locally the moment it lands.
Say what you want in plain language - the ICP, the signal, the size band. GTM Studio turns it into a sheet plan.
Source to launch, each column computed and its result feeding the next. No blank spreadsheet, no manual lookups - it just fills.
Any column can be a value, a function, an AI prompt, or a live enrichment call - an embedded terminal sits right there the moment one needs judgment.
Every result writes to the sheet as it fills - no dashboard to check, no cloud copy to lose track of. Open the file, it's all there.
GTM Studio ships with every founding seat, alongside the brain, the CLI, and a new production system every month.
