Businesses are categorized based on a number of factors, most usually referring to the growth phases of the business using business size and maturity as the key differentiating factors.
I believe that it is not about the stages of the business, but rather it is about the states of ownership. Businesses are what people make themselves be and the culture of the business is taken from the leaders. Whatever state the leader is in will directly impact the operations of the business, the culture, marketing, positioning, and success.
Discover your state and how you can make that work for you in your small business.
