Traditional B2B outreach is dying under the weight of "spray and pray" volume. ZeroGTM is a precision-engineered, signal-driven engine that transitions your GTM motion from manual labor to Agentic AI Orchestration.
Designed for the modern GTM Engineer, ZeroGTM turns Google Maps into a high-intent lead goldmine, enriched with deep research, and managed entirely from a mobile-first interface.
The 12-tool sales stack has become an operational liability. Between $100k/year human SDRs and "black-box" AI platforms charging $2k/month, the unit economics of scale are broken.
- Saturation: Cold email is flooded; only hyper-personalized, signal-led outreach wins.
- Privacy: Sending your lead data to 3rd party clouds introduces "sync states" and security risks.
- Cost: Task-based automation (Zapier) becomes cost-prohibitive at scale.
ZeroGTM is a local-first, self-hosted alternative to legacy outreach platforms. It treats Infrastructure as Code, utilizing n8n for execution-based orchestration to give you 100% control over your data and deliverability.
- Map Scrape - Hyper-local lead extraction via RapidAPI (Google Maps).
- Contact Mining - Deep-crawl socials, phones, and emails via OpenWeb Ninja.
- DM Identification - Agentic scraping of "About" pages to find true Decision Makers.
- Identity Verification - Precision email discovery via Anymail Finder.
- Data Sanitization - Automated HTTP 200 validation & casualization (removing "Inc/LLC").
| Cost Category | Human SDR (Annual) | OpenSDR (Annual) | Variance |
|---|---|---|---|
| Compensation | $60,000 | $0 | -100% |
| Tech Stack | $3,000 | $6,000 (APIs/Compute) | +100% |
| Management | $12,000 | $2,000 (Ops/Eng) | -83% |
| Total Cost | $98,000 | $28,000 | 71% Savings |
In 2026, "Speed to Lead" happens on a smartphone. ZeroGTM is designed with a Workflow-Simplification UX:
- Thumb-Friendly UI: Swipe to approve leads or trigger AI sequences.
- Offline-First: View your pipeline and research leads without an active connection.
- Push-to-Action: Get real-time intent signals (e.g., "Lead mentioned competitor on Reddit") delivered via mobile alerts.
- Orchestration: n8n (Execution-based for unlimited scale).
- Logic: Python/JavaScript custom nodes for proprietary data manipulation.
- Database: PostgreSQL (Self-hosted) for full data provenance.
- AI: LangChain + Local LLM support (Ollama) for hyper-personalized opening lines.

Hiring for GTM Engineers peaks in January and July. ZeroGTM is built to align with these Q1/Q3 budget resets, providing a plug-and-play system for organizations moving away from volume-based motions toward signal-driven precision.
We are looking for GTM Engineers to help build:
- Reddit "Goldmine" Listeners: Automated intent scraping from niche subreddits.
- Local-First Sync: Enhanced offline capabilities for field sales.
- International Parity: Better localized AI summaries for non-US markets.
