About SC Supply Company, LLC

Built from the Ground Up

SC Supply Company, LLC didn’t start with investors or capital—it started with a simple realization.

In 2001, founder Susan Caldwell recognized a gap in the marketplace. Through her husband’s experience in sales, she saw that contractors and businesses were losing opportunities because they couldn’t find reliable suppliers for essential products. Instead of waiting for a solution, she built one.

With no startup capital, Susan created the company’s first website from her home computer and took a leap—bidding on a job and winning it. That moment became the foundation of SC Supply Company.
