The problem is most start-up founders like to hire in their own image...
If you're not in your 20's, don't drink alcohol everyday, don't have a degree from Stanford/MIT/UC Berkley, and want to get home to see your wife/children by 7PM then you're "not a cultural fit"
And you probably don't want a job with most startup founders.
You're looking for the startup founder who is able to see beyond his own preconceptions, because he will most certainly need that skill to survive in the marketplace.
Then I hope those companies fail because honestly, if you're working a clean efficient 7.5, there is no reason why the work shouldn't get done. Hire GOOD people, not mediocre slaves.
