The Cascade Logic

How Waterfall Enrichment Works

Our proprietary cascade algorithm queries sources sequentially until it finds the best match, validates responses, and returns a complete record.

Smart Provider Search

We check multiple data providers in order until we find your contact information.

  • Providers queried in optimized sequence
  • Stops at first high-confidence match
  • Automatic timeout handling and retry logic
  • Source health monitoring and failover

Response Validation

Each response is validated for accuracy, freshness, and completeness.

  • Email syntax and deliverability check
  • Phone number format validation
  • Company data cross-referencing
  • Data freshness scoring (last updated)

Best-Match Merge

Our algorithm selects the highest-quality data point for each field.

  • Field-by-field quality comparison
  • Confidence scoring per data point
  • Source priority weighting
  • Conflict resolution rules

Golden Record Output

One complete, verified record with 25+ data points returned.

  • Full contact information (email, phone, social)
  • Company firmographics (size, revenue, industry)
  • Job details (title, department, seniority)
  • Metadata (sources used, confidence scores)
