Data and enrichment
Waterfall enrichment
Waterfall enrichment queries several data providers in sequence and takes the first good result for each field, to raise match rates beyond any single source.
Why it matters
No single provider has every record, and coverage varies by region and role. Querying providers one after another fills more fields than any one source can, which lifts match rates and reduces the gaps a rep hits. For teams that need high coverage, the waterfall approach is how they get it without betting on one vendor.
How it works in practice
A waterfall runs a record through providers in a set order. For each missing field it asks the first provider, and if that comes back empty or low-confidence it asks the next, stopping at the first good answer. This repeats per field, so a single contact might get its email from one source and its phone from another. Cost is controlled by ordering cheaper or higher-hit providers first.
Common mistakes
A common mistake is running a waterfall without verifying the winning result, so you accept the first answer even if it is wrong. Another is a poor provider order that spends on expensive sources before cheaper ones would have answered. A third is chasing coverage so hard that accuracy drops.
How hubsell approaches it
hubsell focuses on verifying each contact at the point of use, so the result you get is checked when you need it rather than accepted as the first available answer from a chain of databases.
