Users can configure enrichment waterfalls for emails, phone numbers, company data, technographics, and custom attributes, with the system automatically deduplicating and validating results. The platform supports over 50 data sources including LinkedIn Sales Navigator, Apollo, Hunter.io, Clearbit, ZoomInfo, Lusha, RocketReach, and specialized industry databases, enabling enrichment rates of 70-90% compared to the 40-50% typical of single-source solutions.
