In the first paragraph the author states: 'I started a company called Trace3 with $100 and grew it to over $400 million in revenue'.
The article it's self is very useful, and I think the advice the guy gives is totally on the money. But to be fair, the article does not cover how to go from $100 to the first million. That's the really tough part. Going from 1 million to 10, and then to 100, and so forth isn't a walk in the park, but that first step is always the toughest.
