The spreadsheet that lives in your IDE.
Describe your target list. GTM Studio fills every column, saves locally, and opens Claude Code when judgment beats a formula.
A spreadsheet where every column runs.
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.
Any column, any type
Input, sandboxed function, LLM prompt, or live enrichment call - one row, four ways to compute a cell.
A real engine underneath
Every sheet still runs sourcing, enrich, segment, copy, and launch. A pipeline that executes, not a picture of one.
Terminal on tap
An embedded Claude Code terminal sits inside the sheet, so you never leave the workbook to think through a hard cell.
CLI-first, by decision
legion gtm-studio on your PATH is the real agent seam - no hidden API to reverse-engineer.
Reads from the brain
Grounded in the GTM MCP - 1,626 campaigns of proven pattern, so its judgment starts from real outcomes, not a cold model.
Cost and state, always visible
Nothing runs in a black box. Spend and progress surface live, so you know what a sheet cost before it's done.
Watch the columns fill, one at a time.
Every GTM Studio sheet is a live workbook. Each column fills as it runs, and the result saves locally the moment it lands.
A live look at GTM Studio - open a column's menu, run it, and watch the enrichment land across 43,210 rows.
One description in. A saved, legible sheet out.
Describe the list
Say what you want in plain language - the ICP, the signal, the size band. GTM Studio turns it into a sheet plan.
It fills in, column by column
Source to launch, each column computed and its result feeding the next. No blank spreadsheet, no manual lookups - it just fills.
Drop in when a cell needs you
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.
Everything saves locally
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.
Every product GTM Studio plugs into.
Describe the list. Let GTM Studio fill the sheet.
GTM Studio ships with every founding seat, alongside the brain, the CLI, and a new production system every month.
