Though this was over 20 years ago, it's an example of a founder who was an expert in business. Now what I wonder is how the two found each other. Was Cook the one generating the ideas and product vision? Then along the way he found Proulx?
Believe it or not, most billionaires are experts in business. Most startup billionaires don't found companies like Microsoft, they found companies like U-Haul and Grey Goose.
(Although I think there are a disproportionate number of CEOs with engineering backgrounds.)
