Mark Sabbagh didn't start with a business degree or a five-year plan. He started on his father's factory floor in Brooklyn, making hair gel and toothpaste, learning the work ethic that would define his career. By his early 20s, after losing his mother at 22 and working everything from bus boy to door-to-door sales, Mark pivoted into the insurance industry, then built Diamond Trading Group into a $30M sourcing and trading operation-all from a desk and a phone.
But the real story isn't just about the number. In this conversation with Samuel McVay, Mark reveals what actually builds sustainable businesses: deep customer empathy. Whether he's sourcing products on Amazon or managing appliance distribution, Mark operates from a principle that cuts through noise-understand your customer so completely that you never lose sight of the real impact your product has on their life. He uses the example of a family needing to put food on their table, or a parent buying an expensive appliance. That empathy is the foundation of ethical business decisions.
This episode is a master class in business philosophy wrapped in a hustler's origin story. Mark talks network-building, the difference between quick wins and sustainable growth, and why ethics aren't soft skills-they're competitive advantages.
From Brooklyn Factory to $30M Empire: Mark Sabbagh's Path to Building Real Business
Mark Sabbagh grew up on the factory floor of his father's Brooklyn manufacturing business. Not metaphorically-literally. His father ran a beauty products factory that made hair gel, toothpaste, baby wipes, and creams. Mark was working summers by age 12, and when school ended, so did his childhood. He became a bus boy, a beach worker, a door-to-door sign salesman-anything that paid.
"I was a terrible student," Mark laughs when recounting his early years. But what he lacked in classroom performance, he made up for in hustle mentality. That mentality came from watching his father work relentlessly, and from an early loss that shaped his entire worldview: his mother passed away when Mark was only 22, when he was just starting his career. That moment crystallized something for him-time is finite, and how you spend it matters.
The Real Turning Point: Understanding Your Customer
By his early 20s, Mark was working in insurance. Then came the pivot that would define the next chapter: he built Diamond Trading Group, a $30M sourcing and trading operation. The scale is impressive, but it's not the headline. The headline is how he built it: from a desk and a phone, by understanding supply chains, customer needs, and the ripple effects of his decisions.
In our conversation, Mark articulated something that many businesses miss in their pursuit of growth. When you're sourcing products or running a distribution operation, you're not just moving inventory. You're affecting real people's lives. A stolen shipment doesn't just cost money-it takes food off a family's table. An appliance purchase isn't just a transaction; it's an expensive, important decision for the customer buying it.
This depth of thinking is what separates businesses that grow sustainably from those that burn out. It's the same principle that drives local service businesses to invest in their online presence and local SEO-because when you truly understand that your HVAC customer needs reliable service to keep their family comfortable, you're not just optimizing keywords. You're solving a real problem. That customer empathy translates into better service, better reputation, and real growth.
Mark's business philosophy mirrors this: "That's how you build real business-when you understand the customer all the way down to the root and understand the positives and the negatives that can happen in those situations."
The Hustle Never Stops
What stands out most about Mark is his energy and his authenticity. He's not interested in shortcuts or pretense. He's built multiple ventures because he's wired to build, and because he learned early that economic security requires constant motion. But that motion is always guided by the same north star: real customer value and ethical decision-making.
For entrepreneurs and business owners listening, Mark's story offers a clear lesson: your origin doesn't determine your outcome, but your principles do. Whether you're building a $30M trading company or growing a local service business, the fundamentals are the same. Understand your customer. Do the work. Make decisions that you can defend. And never lose sight of the real impact you have on people's lives.
