From $500 to a Million-Dollar Business: The Accidental Entrepreneur Who Reinvented Air with Mark McNally

What if the thing that changes your life starts with a pizza box?

In this inspiring and down-to-earth episode, I sit down with Mark McNally, founder of Filters Direct USA, DJ-turned-entrepreneur, and a true example of what it means to build with integrity. Mark shares his story of moving from Ireland to the U.S. with only $500, working his way up from an HVAC laborer to buying the company—and then launching his own direct-to-consumer air filter business from scratch (literally, with a pizza box prototype).

We talk about the heart behind mission-driven entrepreneurship, how to lead values-first teams, and why your environment (and the air you breathe) could be the most overlooked factor in your health and success.
