Automated Lead Generation & Contact Enrichment with Hunter.io and Perplexity AI
# Who is this for?
This template is ideal for B2B founders, solopreneurs, growth marketers, SDRs, or anyone looking to scale their lead generation and enrichment with **no-code tools** to low-code tools.
Whether you're building your first lead pipeline or upgrading a manual spreadsheet, LeadAIgen automates the entire discovery, enrichment, and logging process using AI and verified email data.
---
# What problem does this solve?
Lead sourcing and enrichment are time-consuming, inconsistent, and often require multiple tools or manual scraping.
This workflow solves that by chaining AI + contact discovery, validating everything, and storing clean, structured data in Google Sheets - ready for outreach or CRM sync.
---
# What this workflow does:
- Accepts an industry/topic prompt via chat trigger or Telegram.
- Uses OpenRouter (Perplexity) to find 15 relevant companies with domains.
- Parses the results, filters duplicates based on your Google Sheet.
- Enriches each domain with up to 3 real personal emails using Hunter.io.
- If no emails found, Fallback AI tries to locate general email info.
- Updates your Google Sheet with all valid enriched leads (status: “Enriched”).
- Runs in safe batches of 10 to protect your API limits.
- Includes logic to clean data, validate JSON, and slice leads.
---
# Setup:
- Create Google Sheets, Hunter.io, and OpenRouter credentials in your n8n instance.
- Import the JSON workflow.
- Set your OpenRouter model (default = Perplexity Sonar Large).
- Connect your Google Sheet (must contain a header row with `Domain`, `Status`, etc.).
- Paste your Hunter API key into the Hunter.io node.
- (Optional) Add Telegram Bot trigger to chat with your lead generator.
