Why do most start up business fail?

Hello Marie, there might be so many reasons for that.But i will write here some of the common reasons that might be helpful: 1.do not have enough information and research about the market dynamics(supply, demand, competitors 2.arising a new strong competitor after start up 3.cash flow management issues 4.do not understanding ROI 5.D not analyzing strategic sales channels 6.cost anlaysis 7.new trends in the sector 8.sometimes new start ups might not be enough so the entrepreneurs might need an extra income to go on 9.sometimes the owners might need a third eye or outsourcing professionals for management or consulting 10.do not analyzing the customer

the major fail is do not start! if you have some idea, just start. Start is to put on the paper, to make the planning, ask people what they think about, solve the objections.
