Twitter has revolutionized the way we communicate 140 characters at a time and has catapulted its co-founder, Jack Dorsey, to legendary status.
The Wall Street Journal named him "innovator of the year" in 2012. Fortune recently ranked him second on their top 40 under 40 list. Reuter's and Popular Science have compared him to Apple's Steve Jobs.

Dorsey's next project, Square, could be even bigger. The rising star now has his sights on commerce; changing the way you and I buy and sell goods.

Started in 2009, the company allows merchants of all shapes and sizes to accept any form of payment they choose – cash, checks, or credit cards - and replaces the bulky cash register with Apple's (AAPL) iPhone or iPad.
"We want to make commerce easy and if we make it easy we can help our sellers grow and really give them time back to build their business and focus on what’s important to them," Dorsey tells Breakout in the attached video. "The merchant doesn’t have to think about which card brand is coming over the counter and if it’s cash or if it’s check, they just focus on their business and that’s what we want to enable them to do."
That may sound like change enough, but the potential game-changing feature of the company is the data it provides to users.
"What’s your most popular item, what happens on a Tuesday, what’s your most popular day, what happens when it rains? These are pieces of data that a lot of local businesses, a lot of neighborhood places just don’t have access to because it’s spread out over so many systems," Dorsey explains. "But Square makes it easy. You can literally watch in real time."
