ZoomInfo is built for firmographics, org charts, and contact records keyed on a company domain or a person's name. It has no view of what developers are doing. DataForGTM is the opposite: it starts from a GitHub identity and developer activity, and returns the person and the buying signal — as tools your AI agent can call.
ZoomInfo answers "who works at this company, and how do I reach them?" DataForGTM answers "this GitHub user is evaluating my tool — who are they, and where else is this happening?" If your GTM motion is developer-led, the entry point is a GitHub username, a starred repo, or an org's open-source activity — none of which ZoomInfo indexes. DataForGTM is honest about its scope: it does not sell org charts, phone numbers, technographics, or general B2B contact lists. For that, ZoomInfo is the right tool.
| Capability | DataForGTM | ZoomInfo |
|---|---|---|
| GitHub username → LinkedIn (person-level) | Yes, as an API | No — keys on domain / name / LinkedIn URL |
| Developer & company GitHub buying signals | Yes | No |
| Enterprise firmographics & org charts | No | Yes (its core) |
| Phone numbers & verified work emails | No | Yes |
| Technographics & intent across the web | GitHub-only, narrow | Broad |
| Agent-discoverable MCP / OpenAPI | Yes | Limited |
| Self-serve, no demo, no seat | Yes | No |
| Pricing | Prepaid, ~$0.30 per resolved hit, misses free | Annual seat-based contract |
Point any MCP-aware client or OpenAPI connector at the endpoint and authenticate with a bearer API key:
# Resolve a GitHub username → LinkedIn
curl -X POST https://dataforgtm.ai/api/v1/deanon \
-H "Authorization: Bearer $DATAFORGTM_API_KEY" \
-H "Content-Type: application/json" \
-d '{"githubUser":"torvalds"}'
# A successful resolve costs 2 credits (~$0.30). Misses are free.
If you sell into mid-market or enterprise on firmographics — company size, industry, revenue, hierarchy — and you need verified direct dials, work emails, and decision-maker contact data at scale, ZoomInfo is the stronger choice. It also covers buyer intent far beyond GitHub. DataForGTM is purpose-built for one thing: turning developer activity on GitHub into named people and intent. Many teams run both: ZoomInfo for account coverage, DataForGTM for the developer signal ZoomInfo can't see.
