What problem does it solve? Building a B2B prospect list requires querying multiple contact databases with different APIs, filter schemas, and pricing models, and a wrong filter or provider choice wastes paid credits on empty or irrelevant results. ## Core Features & Use Cases - Company Mode: Finds contacts with specific roles at companies from an existing list, using a segment-routed waterfall across FullEnrich Finder, BetterContact Lead Finder, and Pipe0 searches (amplemarket, crustdata, parallel). - Persona Mode: Builds prospect lists without a company list using Parallel FindAll and structured Pipe0 persona filters, with mandatory title and region anchors to prevent unbounded billed searches. - Cost-Controlled Execution Protocol: Enforces sandbox validation, a 15-record test batch with user review, incremental CSV saving, and deduplication by LinkedIn URL before any full run. - Use Case: Given a CSV of 80 DACH e-commerce companies and a target role list, run the finder waterfall to recover contacts with LinkedIn profile URLs, then write the consolidated result to csv/intermediate/contacts_found.csv ready for enrichment. ## Quick Start Find marketing decision-makers at the companies in my target list and save their LinkedIn profiles to a CSV.
