Maybe you're a coach or well known for what you do in your industry, establishing a corporate name may only be needed if you want to grow or diversify from what you currently do, but a corporate brand name will also protect your personal brand name.
You're not sure if you need a personal brand or corporate brand yet
You’re still uncertain what the direction of travel is for you and your business. Focus on your vision, where do you see yourself and the business in 5 years time, is it still just you and will you be well known by then? You don't need to decide right now, but maybe soon. Consider using a descriptor with your name to let people know more about you.
You've probably established a corporate brand name already
You’re growing a business that will outlast you but it is still important that your personal brand name is known. Make sure people know who you are and what you’ve created as well as establishing your corporate brand name.
