Jack Dorsey's management of his 80 hour work week appears to be paying off.
The young millionaire splits his day running two of the tech world's hottest startups, a task he says he can only do by keeping both companies within blocks of each other and his home and having laser like focus on what he does during the day.
Monday Fastcompany.com put out its list of the world's 50 most innovative companies and both Dorsey's Square and Twitter made it high on the list.
Square, the mobile credit card-processing company, was ranked No. 5, just behind Apple, Facebook, Google and Amazon, and one spot ahead of Twitter.
The micro-blogging site was ranked No. 6 for "amplifying the global dialogue."
Apple and Google came in about where they were expected and Facebook couldn't be ignored for its 800 million users and the fact that it will shortly be the world's hottest IPO -- ever.
Other Bay Area companies to make the list included SolarCity, Tesla Motors, Airbnb, Dropbox, Genentech, LinkedIn and Y Combinator.
