Waterfall B2B enrichment that maximizes the contact match rate, especially on mobile numbers, at the cost of variable pricing.

FullEnrich is a B2B contact enrichment tool built on the "waterfall" method: instead of querying a single data source, it combines several and keeps the best result, which noticeably raises the match rate for found contact details. Built by a French team, it targets sales and growth teams.
You provide a name and a company, and FullEnrich finds the professional email, personal email and mobile number by querying dozens of providers in a waterfall. Payment works on a usage basis, in credits, with a cost per data type (one credit for a work email, more for a mobile number). It integrates with CRMs and prospecting tools like Lemlist.
Against a classic single-source enrichment provider, FullEnrich's waterfall raises the success rate, especially on mobile numbers, harder to obtain. It comes close to Pharow's approach, but focuses on pure enrichment rather than list targeting.
The credit-based model makes cost variable and sometimes hard to predict at large volumes. Quality depends on the underlying providers, and as with any enrichment, some contacts remain unfindable. It needs to be paired with a sending tool to run campaigns.
