# gtm-sdk: Go-To-Market SDK and CLI for Modal
> Layered Python SDK and Typer CLI for account research, enrichment, CRM sync, and outreach workflows, deployed as Modal serverless functions.
**gtm-sdk** is a layered Go-To-Market toolkit: a thin Typer CLI on top of workflow
orchestration on top of single-SDK adapters. It deploys as Modal serverless functions
and is consumable as an editable Python package.
## Architecture
The repo enforces a strict layering:
| Layer | Directory | Role |
| ------------- | ----------- | --------------------------------------------------------------------------------------------------------------- |
| CLI | `cli/` | Thin command surface. Parse flags, preflight, call `src/`, render output. No business logic. |
| Orchestration | `src/` | Multi-step workflows chaining adapters. Modal `@app.function` / `@modal.fastapi_endpoint` decorators live here. |
| Adapters | `libs/` | One folder per external service (Attio, Apollo, Cal.com, Fathom, …). No cross-lib imports. |
| Data products | `data-gen/` | Independent, composable data generation and enrichment pipelines. |
| Webhooks | `webhooks/` | Standalone Modal webhook handlers, deployed individually. |
