OpenGTM vs TargetWise

OpenGTM is an open-source, self-hosted workspace for go-to-market teams and their agents. It handles lead sourcing and enrichment, AI research with cited answers, buying-intent tracking and sending qualified records to other tools. Workbooks combine imports, formulas, HTTP columns, enrichment waterfalls, AI research and output columns, with estimated spend visible before runs. Teams can segment live audiences, monitor hiring and buying signals, and schedule refreshes and automations. Listed activation destinations include HubSpot, Salesforce, Slack, Sheets, Airtable, Instantly, Smartlead, webhooks, warehouses and consent-gated ad audiences. The workspace is also available through REST, webhooks and an auditable MCP server with scoped read and write access. The project says data remains on the user's infrastructure and external calls use provider keys selected by the user. Teams can set workbook budgets to stop paid calls at a ceiling, although provider charges may apply. The software is free under AGPL-3.0. Installation requires Git, Docker with Compose v2 and roughly 4 GB of RAM. The project is pre-1.0; public multi-tenant hosting needs further work beyond team-controlled Compose deployment.

TargetWise enriches contact and company data and offers reverse-email lookup through REST API and MCP access. Its contact waterfall checks more than 15 specialist sources for requested work-email or business-phone fields, then returns a normalized result. Responses distinguish returned fields from unresolved ones and include source provenance and retrieval time; only successful results consume credits. Company enrichment accepts identifiers such as a website, LinkedIn page, registration or VAT number, or ticker, and returns available profile data one company at a time. Unavailable company fields remain unresolved rather than being guessed. TargetWise provides implementation guides for HubSpot, Salesforce, and n8n, plus an AI-client guide for Cursor and Claude Code. The maker describes workflows in sales, marketing, HR, market research, CRM data quality, embedded products, and AI products. Contact coverage varies with geography, role, source availability, and supplied identifying context. The Free plan includes 20 work emails and five business-phone results. The Core plan costs $49 a month, with a 49 USD monthly usage balance included.
