What Is Waterfall Enrichment?

Waterfall enrichment is a data enrichment method that runs each contact record through a defined sequence of data sources until all required fields are populated. If the first source lacks a field (like a mobile number or LinkedIn URL), the next source is automatically tried — continuing down the “waterfall” until the field is filled or all sources are exhausted.

How waterfall enrichment works

  1. 1.A contact record enters the enrichment pipeline with some fields missing — typically email, phone, or firmographic data.
  2. 2.The system tries source 1 (e.g., Apollo). If the field is populated, it moves on. If not, it falls through to source 2.
  3. 3.Source 2 is tried (e.g., Clay’s waterfall network). If the field is found, the record is updated. If not, source 3.
  4. 4.This continues until all required fields are populated or the source list is exhausted.
  5. 5.The enriched record — now complete — is scored against your ICP and routed into sequences or CRM.

Why waterfall enrichment matters for outbound

Single-source enrichment produces fill rates of 40–60% on a typical B2B list. Waterfall enrichment regularly achieves 80–90% fill rates because no single data provider has complete coverage. The difference matters because incomplete records mean wasted outreach — you’re paying to contact people whose information is wrong or missing.

How Suprflo uses waterfall enrichment

Suprflo runs waterfall enrichment from 50+ data sources as the first stage of your GTM pipeline. Every contact is enriched, deduped, and scored 1–10 against your ICP before a single outreach step runs. Enrichment isn’t a side project or a CSV export — it’s the foundation of an engineered pipeline.
