As of now, I do not plan to start any kind of business with partner because I do not have many friends who could start a business with me and become my partners.
I see nothing wrong with starting a business with a business partner. People decide to have partners in businesses for many reasons such as the financial capacity of your business partner, how knowledgeable that they are about the business and many more reasons. So, you can check and decide why you need a partner in the business that you want to start or is it something to start alone.
