Why do you feel that profits, market cap etc. are poorer metrics to judge a business success than your metrics? You should write about that.
Flat works in small companies. It is impossible once they get above a certain size. They cannot be "more successful".. because they will eventually need to restructure as they grow larger.

Some Googlers have autonomy, some don't. I don't care to get into this discussion because for all my criticism of it, I really admire Google (the engineers and the vision, if not the middle management and HR) but I'll just say that the Googlers who've established a basic autonomy are very happy. They pick their projects and have little interest in leaving, unless to do their own startup. However, there's an underclass who face manager-as-SPOF and live or die by their "calibration scores". For them, Google is a closed-allocation company and these people are not happy.
You don't need "flat" structure outright, but open allocation is non-negotiable in technology in 2013.
- The founder have enough money that they never need care about it again. - Employees are significantly happier on average than Walmart employees.
Those are the only metrics I care about.
