Also keep in mind, he graduated with a CS degree, not a business degree, and he's in a small business now.

"I was hired soon after college (computer science degree) and rose up the ranks from product development"

So this guy started with a CS degree, hired into product development for a major tech company, and was promoted from there.

I'm not saying that necessarily translates to starting a company, but I think his advice holds a little more knowing that he worked both sides of the equation (Product development and management).
