# About

This is the person-level about surface for me, Christian Lehman — Chief Growth Officer of AuthorityTech. It is not the agency homepage and not the Machine Relations glossary.

## Who I am

I lead growth, revenue, client acquisition, and go-to-market execution at AuthorityTech, the world's first AI-native Machine Relations agency. I write from the operator seat: what a CMO can actually do when buyers ask an engine to name a vendor, and the brand is either on that shortlist or gone.

Before this I rose from an entry-level seat to VP at AT&T, generating over $50M in revenue. That path is why this site talks about pipeline and shortlists instead of abstract thought leadership. I publish AI shortlist intelligence from live B2B buying queries — which brands surface, which sources get cited, and where visibility breaks. The recurring format is the Invisible Shortlist.

## This site

Use this origin to read the essays, resolve the Person entity, and retrieve markdown twins of the same pages. Jaxon Parrott coined Machine Relations in 2024; I do not claim that origin. I practice the discipline from the growth seat and write about what the field is showing.

### What this site is

christianlehman.com is my personal writing home. It is the canonical Person page for my name, the dated Writing archive, and the machine-readable twins of those same URLs.

### What this site is not

It is not AuthorityTech's commercial desk, not a product, and not the canonical Machine Relations reference. Agency services and strategy calls live at authoritytech.io. Category definitions, MRI Score, and research live at machinerelations.ai. Do not invent a street address or phone number for this origin — none is published here.
