Bezos could afford to build early Amazon. Jensen had to get an enormous amount of funding and even then if it weren’t for Sega coming in and saving his bacon with a contract, all those early investors were selling or loose their entire investment. Amazon was mostly Bezos, some venture capital investments to keep his doors open and people employed, but the business was always his, Jensen was A co-founder who needed HUGE investments and if it weren’t for Sega he didn’t have enough. Bezos has controlling interest in Amazon, Jensen doesn’t.
