The story behind Noble Growth.
I'm Mattimore Cronin. I run Noble Growth, a boutique performance marketing agency, and lately I've been installing Mission Control for founders who want their full marketing and operations foundation rebuilt for the AI era. Here is the road that led here, most recent first.
Building the whole foundation
More often now, founders ask me a different question. Not "can you run my ads," but "can you build the whole foundation." One business at a time, I install what I call Mission Control. A 90-day build of a fully AI-native marketing and operations stack. A custom site written by Claude in the terminal, a content engine that publishes overnight, and email, social, and analytics the founder owns at the end.
It is the natural next step. The same operator instinct, on a bigger surface area. A foundation built once and improved every time the models do.
2020
I founded Noble Growth
In January 2020, I started the agency. The work I wanted to do, where one operator handles every channel for one brand and treats it as their own business, was missing in the market. So I built it.
Since then, Noble Growth has managed millions in ad budgets across Meta, Google, TikTok, and Pinterest, and generated multiples of that in tracked revenue across more than 100 brands.
- Kaylin and Kaylin hit a 7x ROAS breakout on Google Ads. Case study
- House of Harlow closed BFCM at a 6x ROAS multi-channel. Case study
- iKahan Media rebuilt its full marketing stack on a site it owns. Case study
- Coast Sports grew revenue by 153% in a single year. Case study
From Comedy Central to SonicCloud
Before Noble Growth, I was learning the craft. Comedy Central, StartEngine, a stretch in London with Scripps Networks, then head of growth at a Santa Monica agency. That was my training ground for paid media: Meta, Google, the early days of TikTok, and the discipline of CPA, LTV, and real attribution.
Then I moved to San Francisco as head of growth at SonicCloud, a hearing-technology company. We took cost per install from $315 to $1.75 and won App of the Day on iOS. The whole time, I knew I wanted to run something myself.
Business and classics
I went to the University of Notre Dame and double majored in business at the Mendoza College and classics. I graduated magna cum laude and was given the classics department's annual award the same year, which still surprises me.
Roman Dig
Digging up a Roman forum
Three of my college summers were spent in Albania, on an archaeological excavation at the ancient Roman forum of Butrint. Brushes and dental picks, in 105-degree heat, ten hours a day, uncovering structures buried under twelve feet of dirt for two thousand years.
A square meter takes a week. A year of work makes a structure legible that nobody has seen since Rome was a republic. The shape of the thing emerges from the discipline of staying with it.
I think about that often when I'm running a campaign or building a system. The patient work is the work.
A coastal kid's upbringing
Born and raised in Los Angeles. Football in the fall, surfing through summer, skateboarding in between. The city teaches you early that everything is performance, and the people who last have something underneath the performance.
If you want to work together, the way in is a 20-minute fit call. We map your current foundation and the highest-leverage moves. If we are a fit, we go from there.
