Chief Growth Officer, AuthorityTech

About
The growth seat
This site is my personal writing home — operator notes on AI visibility, the Invisible Shortlist, and what actually shows up when a buyer asks an engine to name a vendor. I lead growth, revenue, client acquisition, and go-to-market execution at AuthorityTech. Jaxon Parrott coined Machine Relations in 2024; I write from the growth seat about how that discipline shows up in live B2B buying queries.
What I publish here
I previously rose from an entry-level seat to VP at AT&T, generating over $50M in revenue. That is why the essays stay close to pipeline, shortlists, and citation sources instead of generic marketing advice. Use /about, /contact, and /privacy when you need the person-level pages. AuthorityTech commercial work lives on authoritytech.io. Category definitions live on machinerelations.ai.

All →The Training Software Site AI Cites More Than Forbes
A pitch list for learning and training software, built from all six published buyer shapes, and the source-class label that hides the strongest target from anyone who filters on it.
Citation Growth Does Not Mean Sales Gets Named
Machine Relations Index data on 14,447 AI citations show why naming rate, not citation count, is what a sales team can act on.
Healthcare Software's Top Cited Source Isn't Press
In the Machine Relations Index's Healthcare Services segment, the top-citing 'editorial publication' domain is an EHR vendor's own site. Here's the pitch list the data actually supports.
Two Publications With the Same AI Citation Rate Are Not the Same Buy
Of the 99 publications the Machine Relations Index scores, the median one is in the cited set on 24 of 130 observed days.
How to use this site
Read this as a personal operator notebook, not an agency landing page and not the Machine Relations glossary.
