There is a company in Pennsylvania doing billions of dollars a year in business.
Privately held. Hundreds of locations. One of the largest of its kind in America.
And most people have never heard of it, including plenty who drive past its yards regularly.
That is not a marketing failure. It is the intended result.
Because the company does not sell to you. It sells to the contractor building the house down the street, and that is an entirely different business with entirely different rules.
Understanding the difference explains a great deal about why some companies advertise constantly and others operate at enormous scale in near silence.
