The Econo Company is a company that makes food. Two of its products are bran muffins and beans. In the episode "A Glass of Warm Ed,"Ed went on a sleepwalking rampage, consuming all the neighborhood's food. This food included a large box of Bran Muffins which were labeled "Econo Bran Muffins." This may indicate that they are available in large boxes for purchase, or that they were stolen from a nearby store or warehouse. In the episode "O-Ed Eleven," one can see a box labeled "Econo Beans" in Eddy's Brother's room. The company's location itself has never been revealed; it is likely that it is a large wholesaler of foods.
The company may be Italian because the name "Econo" translates to "Here you go" in English.
Danny Antonucci's family is also Italian, adding further prevelance to this theory.
The company's name may also be a reference to the real world food company Econo Foods.
