Companies that are more or less invisible because they make the products that consumer products are made of, or make it possible to sell consumer products. Companies like Dupont ,BASF, U.S. Steel that make the products that our products are made from. True Manufacturing that makes commercial refrigerators would be good. Their units are everywhere from department and grocery (by registers to sell cold drinks) to bars to sub shops and pizza joints. We see them every day, yet we don’t notice them.
I think it could be an interesting to learn more companies that are seen and not heard.
