Adrexon One domain in. Full outreach out. Adrexon finds lookalike companies, surfaces C-suite decision-makers, resolves verified emails, and sends personalised outreach - zero manual steps between stages. Built with Python, Flask, and a 4-API chain (Apollo.io · Prospeo · Brevo). Includes a CRM collaborative workspace, suppression list, resumable runs, rate-limit resilience, and a safety checkpoint before any email fires. A production-grade B2B SaaS tool - not a demo.
