FullEnrich

FullEnrich is a waterfall enrichment platform that queries many data providers in sequence to find verified B2B emails and phone numbers, charging only for successful lookups.

FullEnrich solves the accuracy problem of single-source contact data by using a waterfall model. It queries providers like Apollo, Hunter, Dropcontact, Snov.io, Clearbit, Kaspr, and Prospeo in an algorithmically ordered sequence, so each provider fills the gaps of the previous one, driving match rates of 80% or higher on typical lists. The credit model means teams only spend when a lookup succeeds, which is more efficient than paying flat fees to several separate data vendors. This consolidation can replace multiple subscriptions with one enrichment layer. FullEnrich is aimed at sales teams, RevOps, and outbound agencies who need reliable email and phone data for prospecting and often plug it into tools like Clay, CRMs, or sequencers. It competes with BetterContact and single-source providers, differentiating on multi-provider hit rates and pay-for-success pricing.
