I’ve spent the last decade refining paid growth loops and creative feedback systems for subscription apps valued between $500M and $5B. What I learned is that there is a massive gap between a "media buyer" and a "growth architect". Anyone can spend ad dollars, but scaling with the best returns requires a proven architecture where creative strategy, marketing levers, and data infrastructure operate as one compounding engine.

I developed this framework as Head of UA at Hopper, where my creative testing methodology produced 50+ ads hitting over 6-figures in spend each and fueled a scale to $4M/mo.

I now install this same architecture in early-stage apps to bridge the gap between early traction and a controllable, scalable growth engine.

FAQS

Questions? Answers!

Quick answers to common questions.

How is this different from a standard agency?

Most agencies are "button pushers" who execute without strategy. I function as a Growth Owner, managing your strategy, systems, and measurement end-to-end. You aren't just buying ads; you’re buying a partner who owns the results so you can focus on the product.

What is your approach to ad creative?

I don’t make the ads; I build the feedback loop that scales them. I own the creative operations—sourcing elite designers, managing the testing process, and providing iterative analytics that turn data into winning concepts. By factoring creative production costs directly into your ROAS, I ensure your investment is a transparent growth lever rather than a "black box" expense.

What is your pricing structure?

I use a hybrid model: a fixed retainer that transitions into a percentage of ad spend once we hit scale. This structure covers the initial systems-building and then shifts to replace the base fee entirely as we grow.

How do you manage your bandwidth?

I intentionally limit my client base to a handful of apps to ensure I can deeply own your growth problems— it's the only way to properly scale. While I use tools and an assistant for low-level operational tasks, I personally own the strategy and make every major decision. You get a systemized process with the high-level accountability of a dedicated partner.
