E-COMMERCE GROWTH,
GROUNDED IN FINANCIAL REALITY
FourThree works with DTC and e-commerce brands to build customer acquisition and retention strategies that are creatively sharp and financially grounded. We execute paid media campaigns, advise on growth strategy, and help founders understand the relationship between what they spend and what they keep.
If you want an agency that can talk to your CFO as fluently as it talks to your creative team — you're in the right place.
Marketing & Finance Are Not Separate Disciplines. They Are Two Views Of The Same System.
Every dollar you spend on acquisition has a financial consequence — and every financial constraint you operate under has a marketing implication. Most agencies only see one side. We were built to see both.
​
That's not just a philosophy. It's the lens through which every campaign we build, every budget we recommend, and every strategic decision we make is filtered. Growth that doesn't connect to financial reality isn't growth. It's just spending.
TOM SANTAGATO
Founder, FourThree Media
I'm a husband, a father of three and a former athlete turned finance guy turned e-commerce strategist — life takes some interesting turns, doesn't it?
​
Day to day I run FourThree, working directly with e-commerce brands on paid customer acquisition and retention. I'm in ad accounts, analyzing creative performance, and advising on strategy every single day. I launched this agency because I kept seeing the same problem: marketing teams optimizing for metrics that didn't connect to financial reality, and finance teams producing reports that couldn't explain what was driving the numbers. Founders were stuck in the middle, making consequential decisions without the full picture.
​
FourThree exists to close that gap — with real execution, real strategy, and a perspective that speaks both CMO & CFO.
​
I love what I do.
We Don't Just Run Campaigns. We Build The Strategy Behind Them.
PAID MEDIA EXECUTION
We build and manage performance campaigns across Meta, Google, TikTok, and LinkedIn — fully executed, not just advised on. Strategy, creative direction, audience architecture, budget allocation, and ongoing optimization. We're in the accounts every day, and we treat your ad spend like it's our own.
CUSTOMER ACQUISITION & RETENTION STRATEGY
Beyond the campaigns, we advise on the full customer lifecycle — from the economics of acquiring a new buyer to the systems that bring them back. What does a sustainable acquisition cost look like for your business model? What does your repeat purchase rate need to be for your growth to be self-funding? These are the questions we help you answer.
CREATIVE STRATEGY
Great performance creative isn't made by guessing. It comes from understanding what the data is telling you about your customer, what's resonating and why, and how to translate that into concepts that stop the scroll and drive qualified traffic. We advise on creative direction, brief development, and testing frameworks that make your creative dollars work harder.
MARGIN OF GROWTH:
Master the Math That Powers Sustainable
E-Commerce Growth
​
The metrics that determine whether or not your business thrives aren't in your ad platform or some fancy dashboard—they're in the relationship between your marketing and your finances.
​
This book teaches the essential math behind sustainable e-commerce growth: contribution margins, break-even ROAS, customer acquisition costs, payback windows, cash flow, etc. The frameworks that connect what you spend to what you keep.
​
Every business has a margin of growth—the space between where you are today and how far you can scale before the economics of your business begin to strain.
​
Understanding that space is the difference between growth that compounds and growth that costs you. This book shows you how to find it, measure it, and expand it over time.
