# OpenGTM

> Self-hosted Clay alternative

Open-source lead sourcing, enrichment waterfalls, AI research, buying signals, and activation — in one self-hosted workspace. Unlike a hosted credit black box, OpenGTM shows the estimated bill before a run; your data stays on your machine and third-party calls use keys you choose.

## Built for

GTM engineers and sales teams that want Clay-style enrichment workbooks without hosted credits, data egress, or surprise invoices.

## Product thesis

Your GTM data engine. Your keys. Your infrastructure.

## Capabilities

- **Clay-style workbooks:** Formulas, HTTP columns, cost-ordered enrichment waterfalls, AI transforms, web research, and conditional logic — from a market, a list, or a workbook.
- **Bring your own keys:** BYOK enrichment across email, phone, firmographic, technographic, hiring, social, and identity providers, with spend ceilings instead of credit burn.
- **Signals in, activation out:** Audience loops with scheduled refresh and entry/exit events feed automations that send qualified records to HubSpot, Salesforce, Slack, Sheets, Airtable, Instantly, Smartlead, webhooks, and warehouses.
- **Agent-ready platform:** REST, webhooks, and a tenant-scoped, auditable MCP server with real read/write tools; PostgreSQL RLS, scoped tokens, idempotency, OIDC, SCIM, and observable workers underneath.

## Evidence

- BYOK keys, not credits
