( CNN ) -- Jack Dorsey might be an unassuming character -- but he 's also a tech titan who reinvented the way the world communicates . And now he 's on a mission to do the same for commerce . The co-founder of Twitter and chief executive officer of Square met with CNN 's Maggie Lake to share his vision on how mobile payments will change the world of commerce . Square , which enables the virtual exchange of cash and goods , is designed to `` give time back to our sellers , give time back to our merchants , so they can really focus on building their business up , '' Dorsey told CNN . `` We do n't want this to just be about payments , we do n't want it to be about transactions -- those are all mechanical things that should be so intuitive that they disappear , '' he said . Dorsey is criss-crossing North America to promote Square and talk to small business owners , whom he sees as key to reinvigorating economic growth . `` What I think is great about technology , and every technology that exists , [ is that ] it increases the number of people who can participate , in our case commerce , '' Dorsey said . `` And , it increases the velocity that they can participate . '' Square , Dorsey added , enables a businessperson to `` start as an individual , you can start selling something , and then you can grow . '' Square is competing in a jammed arena -- mobile payments already exist via Paypal and others -- but Dorsey told CNN its pitch is different . `` A lot of folks are looking at parts of the equation and Square is looking at the entire thing , '' Dorsey said . `` If you 're not solving for the entire experience , you are putting those seams in front of the customers -- and the customers see that . And they have all these friction points , and it actually slows down the business . '' Square aims to have `` one , end-to-end , great , frictionless experience -- and that 's been our focus from day one , '' Dorsey said . Transactions through Square have tripled over the last 18 months , a success that nevertheless remains overshadowed by the Dorsey 's involvement in Twitter . The micro-messaging social network , which has shifted how people and businesses communicate , is valued at up to $ 11 billion and will go public next month . However , Dorsey said Square is an `` entirely new canvas , '' dealing as it does with commerce rather than communication . Both ideas are `` fundamental to humanity ... .both are extremely complex and both companies are trying to make each simple . '' But , Dorsey added , `` they are very very different problem sets and they require different solutions to each one . ''
