Project Overview

BCON is a sophisticated email discovery and verification tool that I developed as a free, self-hosted alternative to premium services like RocketReach. The application intelligently finds and verifies business email addresses using only a person’s name and company information, combining web scraping, email pattern analysis, and SMTP verification techniques.
