Chief Growth Officer, AuthorityTech

I help companies become visible to AI. Chief Growth Officer at AuthorityTech — the world's first AI-native Machine Relations agency. Revenue operator, B2B growth strategist, and practitioner of Machine Relations: the discipline of making brands visible to the AI engines your buyers use to make decisions.


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.

How to use this site

Read this as a personal operator notebook, not an agency landing page and not the Machine Relations glossary.

The essays

The Writing section is the dated archive. Each piece is a CMO-facing note on AI visibility, shortlists, and citation sources. Open any title as HTML or as a markdown twin at the same path plus .md.
