Six years of email. One afternoon to find every warm lead buried in it.
A B2B recruiting client's sales team was cold-emailing strangers while real relationships sat forgotten in their own inboxes. We built a tool that scans full Gmail history, has Claude classify every contact, enriches the real ones and syncs warm leads into the CRM.

Warm outreach beats cold. Nobody has time to find it.
A sales team can feel which relationships are warm, but can't list them across six years and two mailboxes, so it buys a cold list instead.
A small pipeline, built to run unattended.
Read-only Gmail access, one pass through every thread, a five-way classification (customer, prospect, vendor, personal, noise), enrichment for the real ones, and a de-duplicated sync into the CRM.
Output only. Nothing sends without a person.
The tool finds and prepares. Every outreach still goes through a real person, starting from people who already know the brand.
