A sales agency needed a steady supply of verified B2B decision-maker contacts — specifically C-suite and VP-level leads with working email addresses. Manual research was taking their team 30+ hours per week.

The Automation Pipeline

I built a multi-source lead extraction system that pulls from LinkedIn Sales Navigator, industry directories, and company websites. Each lead goes through a 4-step enrichment and verification process:

  1. Discovery — Playwright-based LinkedIn scraper extracts profiles matching target criteria (title, company size, industry, location)
  2. Enrichment — Company website scraper pulls email patterns and contact pages
  3. Email Generation — Pattern-matching engine generates likely email addresses based on company format
  4. Verification — Hunter.io + NeverBounce API integration validates deliverability in real time

Results

The pipeline delivers 1,500–2,000 verified leads per day with 95%+ email deliverability. The client's outreach team went from spending 30 hrs/week on manual research to 2 hrs/week on review and approval.
