The enrichment waterfall queries one provider after another for each requested data point, tracking per-source hit rates so sales and RevOps teams maximize work email, personal email, and mobile coverage across large contact lists.
The same engine runs through CSV uploads, bulk search lists, and an API, and agency licensing embeds it inside client programs. The official product page describes the sequence as covering twenty or more providers with triple email verification, carrier-checked mobiles, and pay-per-verified-find pricing, and positions the approach against single-database tools that report lower find rates.
