Waterfall enrichment

The fact that no single data provider has the best coverage on every field. Waterfall enrichment calls providers in priority order. Accepting the first match. To maximize fill rate while minimizing cost per filled record.

3 to 5. Beyond 5, the marginal lift on fill rate drops below the cost of the additional call. The right 3 vendors usually cover 90+ percent of accounts.

Either lower fill rate (single provider misses the long tail) or higher cost (calling all providers for every record). Waterfall optimizes both axes. Call providers in order, stop at the first hit.

Contact data (email, phone). Different providers have different coverage strengths. Firmographics benefit less because most providers source from similar root data. Technographics benefit a lot because each provider observes different parts of the web.

Yes. Multi-source enrichment is a core capability, accessible through the web app for individual records and through the CLI for batch operations or scheduled runs.
