Everyone knows you can find almost anything you want on the net if you have the time and skill to sort through the garbage. The US company Stratfor uses techniques from the intelligence services to do just that: indeed, it could be described as the Pinkerton's of the information age.
For business users there is also the Findfacts service. Say you lack the time to check out Daewoo's productivity per worker, or rumours of a rival CEO's ill health.
Stratfor, for $29 to $99 (depending on urgency), will come up with the goods.
