A good logo makes clear at a glance which identity you want to radiate as a company or organisation. No company is the same. Even if you have several companies, you probably have other objectives and target groups that you want to address. Together we determine how the appearance should be. For example; businesslike, sleek, classic, modern or illustrative.
A logo is part of your corporate identity. There is more to a house style. In short, a house style is about ensuring that all means of communication clearly match your company. I would be happy to develop your entire house style.
