Jack Dorsey was the brains that came up with Twitter and he has seen his idea become a mainstay in the digital world. With the large fortune he has amassed he is more than entitles to splash it about and he has done just that. Jack bought this $10 million cliff side mansion that looks like something out of a Bond film.

Jack Dorsey is with a reported $650 million so this is hardly breaking the bank. The property is in San Francisco and looks over the Bay. It is 3,734 square feet and the thing that might surprise you is that it only had 2 bedrooms. It has a pyramid skylight that open with the switch of a button.

Many Real estate experts are saying the Jack Dorsey has got himself a bargain as the house had been on the market for four years. The price during that time has nearly halved as it was $18 million.
