Lead Generation & Contact Research Automation | n8n + Claude AI Agent Built a 90+ node workflow in n8n that takes a plain-language lead request from Slack and turns it into a verified, CRM-ready contact list, with no manual research involved.

Claude AI parses the request into a structured ideal customer profile covering company size, industry, region, and role. The workflow then searches for matching companies and contacts, verifies each email through Hunter and MX record checks, and cross-checks speciality, location, and name relevance before anything is written to the sheet.

Every record passes through multi-layer deduplication against the current batch, past results, and related company records, then is routed into Ready, Review, and Rejected tabs with a full audit trail and failure log.

Result from a real run: the client asked for 50 qualified leads. The system delivered exactly 50 Ready contacts, held back 7 for manual review, and filtered out 143 low-confidence or duplicate records automatically.
