It depends on the situation. If it's used as the name of a company or person, then it should be capitalized. But if you're just saying something like "the founders of this company are..." then it shouldn't be.
Like the above contributor said, it depends. No, not in most cases. For example, in the sentence "The founders of Denver, Colorado lived over a century ago," the word "founders" is not capitalized, it is an improper noun. IF it is a person's last name, the name of a place, or any other form of proper noun, then yes, do capitalize it. Of course, if it is at the beginning of any sentence, capitalize it.
