Isn't that just survivorship bias? Almost all startups fail.
IMHO "Almost all startups fail" - not because they don't have a good plan, a great idea, or "fail to start"
They fail because they don't have the motivation (or capability) to push through the inevitable hard times and come out the other side strong and profitable.
It takes a very special dedication to take an idea from start to profit.
And it seems most "Master Plans" are to cobble together a good idea then sell it for millions to a greater fool.
