Jobs and Wozniak proved (at least in the 70s) that a great technical founder could team up with a brilliant marketer and build a huge company from next to nothing.
I seriously wonder if that can happen today. As a technical founder, I have tried to find a marketing partner for years. Every time it has failed miserably as each one proved unable to move the needle.
In my case, it could be the product, but I wonder who has seen success in this day and age.
Jobs was a marketer, a product visionary and a ruthless businessman. You need more than just marketing.
