Per UK & US recent data, for all new start-ups, about 1/2 of them are closed within the first 5 years whilst only 1/3 can endure for 10 years. There are many different reasons causing their deaths, about 45% due to no market demand for their products or services / ignorance of customers' needs / insufficient marketing; 20% because of no right team; 15% because there is no feasible business model; and the rests are originated by their pricing or costing issues; or encountering strong competitors, etc.
