Single-source pure player
An enrichment provider that relies only on its own proprietary database, without aggregating other sources.
A pure player builds and runs its own database. The upside: consistency and control over the data. The downside: its blind spots are structural — contacts absent from its base will never be found, no matter how many queries you send.
Against a pure player, a waterfall approach multiplies coverage odds by querying several bases. For a niche market or a poorly covered country, the coverage-rate gap can be substantial.
