Aside from a few unintentionally funny lines, there's not much to this movie. It's really just the vaguely boring implosion of an egotistical startup CEO's life.
There was an entertaining documentary made a few years ago about a Finnish mobile game startup called Riot-E. It had little in the way of your actual product, but burned through hundreds of millions in bigco funding with a whole host of extravagances before, you guessed it, crashing spectacularly.
I think you nailed it. Tom's character tells us Landshark sells internet strategy advice to ad agencies.
"Pure E. Not E commerce. Not E business. Not click and mortar [...] We help big, greedy advertising agencies sell the useless products of massive, morally corrupt multinational corporations. We advise them on how to aggregate eyeballs."
Update: forgot to mention http://www.mojohd.com/mojoseries/startupjunkies/ which you can watch online if you're not one of the 53 people who get Mojo (I'm number 24, but I still have no idea when the show is on).
