Cascading enrichment across multiple data sources
Last reviewed: March 2026
The Waterfall Enrichment API (Cascading ICP Search) finds people at a company by searching multiple data sources in sequence. You define your ideal customer profile criteria (job title, seniority, department) and a target company domain. The API cascades through data providers until it finds matching contacts, maximizing coverage and match rates.
Features
Multi-Source Cascade
Searches across multiple data providers in sequence, falling through to the next source if the first doesn't match.
ICP-Based Filtering
Define your ideal customer profile with title keywords, seniority levels, and department filters.
Maximum Coverage
The cascading approach ensures higher match rates than any single data source alone.
Company Domain Input
Just provide a company domain - no need to know LinkedIn URLs or other identifiers.
Structured Contact Data
Returns verified contact details including name, title, email, and LinkedIn for each match.
AI Agent Integration
Designed for AI agent workflows - let Claude, ChatGPT, or custom agents find the right contacts automatically.

Frequently Asked Questions
Waterfall enrichment is a data enrichment strategy where multiple data providers are queried in sequence (a 'waterfall'). If the first provider doesn't have the data, the system automatically tries the next one. This cascading approach maximizes match rates and data coverage.
Lead Finder searches a single database with broad filters (industry, location, etc.) to find leads you don't know about yet. Waterfall Enrichment targets a specific company you already know and finds the best-matching contacts there by cascading across multiple data sources.
You can specify: target company domain, job title keywords (e.g., 'VP Sales', 'Head of Engineering'), seniority levels (C-level, VP, Director, Manager), and department (Sales, Engineering, Marketing, etc.).
The number of results depends on the company size and how specific your ICP criteria are. Broader criteria return more results. The API returns the best matches across all data sources searched.
