A Brand that Grows with You
Whether your company is 2 months, 2 years or 2 decades old, it has an identity. Your company's ethic, service and product quality define and shape your identity internally, while your brand reflects this visually.
Your brand is how you choose to present yourself to the world - and it should be timeless. (See Nike, FedEx, or ESPN for examples.)
Your brand is built around your logo and acts as a heart for the rest of the design for your company. The key then is to build a logo that is unique, timeless and representative. From this all of your collateral, promotional material and website should flow naturally. Any material that your company puts out should be immediately recognizable as your brand.
