Co-founded by Jack Dorsey , Co-Founder of Twitter , and Jim McKelvey , Square was established when the latter was unable to complete a relatively small ($ 2k ) sale because he could not accept credit card payments . Now with the tagline ‘ Accept card payments anywhere ’, the company seeks to rectify this issue for others . Named after the squareshaped card readers which were its first products , Square endeavours to be a force of financial inclusion that empowers businesses , from electricians to clothing boutique owners . That mission has clearly found a wide market : the company reported revenues of $ 4.7bn in 2019 – roughly a 42 % increase on the previous year ’ s figure .
