🧠 How the algorithm works

Unlike traditional databases (Apollo, ZoomInfo, Lusha), Waterfall ICP Search doesn't return bulk, outdated data. It uses a multi-layered discovery system called the Waterfall Algorithm:

1. You define your ICPs (e.g., CEO → VP Sales → Director Marketing).
2. The API runs a ranked cascade search, starting with the highest ICP (1) and expanding to lower ones (2, 3...).
3. Each person is ranked and scored by:
   • Job title similarity
   • LinkedIn headline relevance
   • Company and location match
   • Confidence scoring
4. The API outputs ranked contacts by priority—clean, fresh, and highly relevant.

This intelligent ranking ensures your prospect lists are smaller, cleaner, and 2–3× more likely to convert.
Perfect for ABM, lead routing, CRM enrichment, and cold outreach.
