B2B Lead Generation Pipeline
Fully automated B2B lead pipeline with AI enrichment – from data ingest to appointment booking without manual intervention.
About the Project
A sales process based entirely on manual research, manual data maintenance and manual appointment coordination. Every lead meant hours of manual work – not scalable.
The Problem
The target group (energy plant owners in Germany) is registered in the Market Master Data Register (MaStR) – but without an automated pipeline this data source is unusable. Qualification, enrichment and outreach ran completely manually.
The Solution
An n8n-based pipeline on a dedicated Hetzner VPS that taps the MaStR API, automatically enriches leads, prioritizes by purchase probability and books appointments directly via Cal.com – without manual intervention at a single step.
Features
Automatic data ingest from MaStR API – daily updates. AI-powered enrichment and qualification by industry, size and activity. Automated outreach sequences with personalized messages. Direct appointment booking via Cal.com. Self-healing logic for API errors with complete logging in EspoCRM.
Highlights
- 6 systems fully integrated – no manual handoff
- ~15 hours of manual sales work eliminated per week
- Failure rate under 2% through self-healing workflows
- Self-hosted on Hetzner VPS – GDPR compliant, no SaaS dependencies
Challenges
Reliable connection to the MaStR API with rate limiting and error handling. Building self-healing logic for automatic retry of failed steps.
Results
Fully automated pipeline running 24/7. Scalable lead generation without additional staff. Measurable reduction in manual sales work with higher data consistency.
