Square
Founded in 2009 by Twitter’s Jack Dorsey and entrepreneur Jim McKelvey, Square started as a scrappy little device that let anyone with a smartphone swipe a credit card, giving the middle finger to the big banks and their clunky payment systems. Known for revolutionizing the way small businesses handle transactions, Square quickly became the darling of the digital payments world, with its sleek design and ease of use. The company has since expanded its empire to include everything from point-of-sale systems to business loans and even a cryptocurrency platform, Cash App, proving that it’s not just a one-trick pony. Square’s rise has been nothing short of meteoric, but let’s be honest—its success comes from making money look cool and easy, which in the world of finance, is no small feat.
