A self-hosted lead engine: it finds authors in public sources, verifies their published professional contacts and delivers each lead exactly once.
Modus Leads is an internal tool, so there is no public link. It runs searches as background jobs, checks every contact against its source and shows how sure it is about each value.
Every email, phone, website and book carries a verification mark linked to its source page, and a live search funnel shows where candidates drop out while a search runs.
No screenshot: it’s a private tool.
So here’s how it works instead.
Full-stack, end to end: crawler, job queue, verification, database, API and the dashboard on top.
