Before and after

What changed

Before

A SDR sees a job posting on LinkedIn. Forty minutes later they have a name, a maybe-email, no phone, no opener, no CRM record. By the time they get to the call, the hiring manager has talked to four other vendors.

After

The job posting hits the pipeline at 8:00 AM. By 8:47 the hiring manager's verified mobile is in your HubSpot with a 12 hour task. Your Slack lit up with the name, the number, and a one line opener tuned to the role. You call at 9:02.

How it works

The breakdown, gate by gate

Parse the job URL

The agent reads the role and the company directly from the job posting. No copy paste, no manual classification.

Qualify against your ICP

The 7 gate qualifier from your framework runs against the company. If it fails, the chain stops and nothing gets pushed.

Yalc framework

Resolve the right executive

For the role on the posting, the agent picks the exec who owns hiring. Different roles, different personas, different inputs.

Verify the mobile

FullEnrich returns the verified phone number. If FullEnrich returns nothing, the chain skips push and DMs you why.

Push to CRM

HubSpot gets the contact, the note quoting the job posting, and a 12 hour cold call task on the right rep's queue.

Slack DM with the opener

One DM, three lines. Name. Number. Opener that references the role and the company by name.
