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.
