Jack Dorsey is the creator, co-founder, and Chairman of Twitter, Inc. and the co-founder and CEO of Square, Inc. Originally from St. Louis, Dorsey's fascination with urban transit led him to Manhattan, where he programmed real-time messaging systems for couriers, taxis, and emergency vehicles. Through his work, he witnessed thousands of drivers in the field constantly updating their location and activity, inspiring him to create Twitter. Twitter is a simplified and personalized real-time information network that connects millions of people with the stories, ideas, and news they care about every day. Dorsey's dedication to simplifying the complex and making technology accessible to everyone everywhere continued with the founding of Square in 2009. Square enables anyone to accept credit cards and run their business on their smartphone or tablet; removing the friction from transactions and making commerce easy for everyone. Dorsey was recognized as one of Time magazine's 100 most influential people, WSJ Magazine’s Technology Innovator of the Year and was named an "outstanding innovator under the age of 35" by MIT's Technology Review.
