Every company has a brand. Some are better than others.
Something you need to know to make yours better is to understand that it is more than your logo and stationary design. It is even more than your visual identity as a company.
It is more along the lines of the combined experience your user has in dealing with the company. It includes the logo, but goes much farther and deeper. The illustration above from Iryna Nezhynska illustrates this well.
