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
