Data Enrichment Pipeline

When to Use

Use when building or maintaining prospect data enrichment workflows.

Enrichment Layers

Layer 1: Company Data

  • Company name → domain resolution
  • Firmographics: industry, size, revenue, location
  • Technographics: tech stack, tools used
  • Funding data: round, amount, investors

Layer 2: Contact Data

  • Name + company → email discovery
  • Email verification (SMTP check)
  • LinkedIn profile URL
  • Phone number (optional)

Layer 3: Intent & Signals

  • Recent news and press releases
  • Job postings (hiring signals)
  • Technology changes
  • Social media activity

Waterfall Strategy

Try sources in order, stop at first match:

  1. Apollo.io (best for B2B contacts)
  2. LinkedIn API (via Unipile)
  3. Direct HTTP scraping (company websites)
  4. Manual research queue

Data Quality Rules

  • Email must pass SMTP verification
  • Company domain must resolve
  • Deduplicate on email + company
  • Flag stale records (>90 days since enrichment)
  • Track source reliability scores
