What is Waterfall

Waterfall is a data enrichment API built for GTM and revenue teams to get accurate contact info from 30+ data sources in one place. It’s designed to track job changes, find verified emails and mobile numbers, and deliver clean, real-time profiles. Users save time and cost by avoiding multiple vendors, complex contracts, and outdated data. The tool shines when you need reliable, global contact coverage, such as finding decision-makers or monitoring customers in new roles. You start seeing fresh, verified data immediately, with scalable usage and no commitments. It’s great for prospecting, lead scoring, and customer tracking. Waterfall fits into the GTM stack as a unified, scalable enrichment layer with high uptime and flexible API limits. It complements CRMs and outreach tools but isn’t meant for direct email marketing or CRM itself. It’s focused on clean data, not managing campaigns or storing contacts long-term.
