This certainly isn't the Silicon Valley demographic, but I'm not sure what the demographic _is_. I'd be interested to see a breakdown of what kinds of companies were surveyed. That being said, the numbers given are for CXOs, and not specifically founders (though there's obviously a strong overlap). Founders in Silicon Valley, even after raising large rounds, will typically own much more than 5% of the company.
