Absolutely excellent cult film for anyone interested.
The last tech startup I was involved in (I'm really dating myself here ... ) me and the CEO went to make our first pitch on September 12th, 2001.
I still have a box of business cards kicking around describing me as "CTO, zHosting Ltd". They'd make great roach papers if I could smoke (asthma: nature's way of reminding you to "just say no").
(We buried the company at a crossroads with a mouthful of garlic two weeks later. If we'd just been a month faster things could have been very different ...)
