Sales List Creation & Outreach Automation Tool

A sales operations tool that brings list building, company research, contact lookup, and outreach into one workflow.

Challenge

Solution

Built a workflow that collects public company information, scores companies against target criteria, checks contact details, inquiry forms, and social accounts, then connects the result to template-based outreach.

Result

Supported 10,000+ list entries and 500 sends/day
