I saw the following explanation of why startups fail on Quora this morning:
Answer Summary
The top reasons are:
1. No one wants the product created.
2. Management teams lack flexibility to change direction when needed.
3. Resources (funding/time/labor) are managed poorly.
4. Inability or failure to obtain and/or maintain sufficient capital (for a variety of reasons), whether or not managed poorly.
One answer claims lack of luck is the main reason, leading to the conclusion success is random (as luck is random), leading to the conclusion the only way to succeed is to try a large enough number of times.
(Just flip a coin until you get "Heads").
