No Market Need - This is real Ran Out of Cash - nobody wants their product because of "No Market Need" Not the Right Team - unable to build and sell the product because of "No Market Need", so blame the team Get Outcompeted - Everybody buys our competitors products but nobody wants to our product because it doesn't solve their problem ("No Market Need") Pricing/Cost Issue - I don't know how to price the product so that it covers my costs and attracts clients, because I don't understand the market (again "No market need")
I can go on like this for each and every item in this list. Basically, it seems there are two problems on the surface why startup fails. They either build what nobody wants or they expect that clients will come by themselves buying a their product.
First understand your market and their problems, and only after you find a problem they are ready to pay for solution, build that solution.
