Quick question: how big do you think the global freight industry is? If your guess is in the billions, then you're aiming too low. According to some estimates, global logistics generate somewhere in the range of $8 and $12 trillion annually.

For Craig Fuller, that number represents a massive opportunity. His company Freight Waves covers this industry across text, video, and podcasts. But Freight Waves is a lot more than just a trade publication; it also delivers data and intelligence. In fact, it's much more analogous to a Bloomberg LP, which in addition to its massive media business also generates billions of dollars a year from its expensive Bloomberg terminals.

I interviewed Craig about how he built his expertise in freight, where the company sources its data, and why it recently took on venture capital investment.
