The product, being a v0.1 release implemented in C, was of course plagued with data corruption and poor performance. It read /etc/password from disk on every file access. An uninitialized int caused indirect inode corruption every ~millionth write. And so on.
Because of the poor product quality, they lost multiple opportunities, including a bid for early Facebook photo storage. The company never had more than 250 customers and ended up being sold to a Valley stalwart. The CEO and VP Eng were paid out handsomely, of course; preferred converted stock tranches or whatever. My options from 4 years of employment ended up worth $500.
