An open suggestion to the authors/producers/publishers of Founders At Work (which I'm reading at the moment):
What do you think of writing a book 'Founders That Almost Made It'? Using a similar fashion, but talks to startup founders who almost made it big, but didn't quite make it. Perhaps they had to exit via Plan C rather than Plan A, or they just quietly wound down the startup.
Following the adage that people learn more from mistakes, perhaps it'd be just as useful to get information on why they think they failed, than to read about those who have succeeded wildly?
