Marketing Operations Manager
AI Search Optimization (AEO / GEO)
Revenue Operations + Paid Search

David Hendrix

I’m a marketing operations manager with 10 years of experience across marketing, sales, and revenue operations. I manage a $2M budget, lead a team across organic and paid channels, and build the reporting that connects marketing performance to revenue.

My background in physics and mathematics at Clemson University — and leadership training in the U.S. Naval Nuclear Program — shaped how I work: analyze the system, find the leverage, and execute with discipline.

My Experience

Marketing operations that connect strategy, spend, and revenue.

At Gummicube, an Airship company and the leading App Store Optimization agency, I was promoted to Marketing Operations Manager during a $200M acquisition. I manage direct reports across organic (SEO/AIO) and paid channels, own revenue operations and forecasting, and deliver executive reporting to Airship leadership.

Before that, I spent years as a webmaster, technical SEO specialist, and Google Ads manager — including consulting and teaching for small business development centers. That range, from hands-on implementation to budget ownership, is what lets me translate between the technical work and the revenue conversation.
