Jim McKelvey's Bio
James Morgan McKelvey Jr. is an American entrepreneur and co-founder of Block, Inc. (formerly Square) with Jack Dorsey. Born in St. Louis, Missouri, he studied economics and computer science at Washington University before launching a series of ventures that blend technology, art, and civic impact.
His career defies easy categorization: he authored a programming handbook as a teenager, built a CD-cabinet manufacturer, spent years as a glassblowing instructor, and co-founded Mira Conference Inc. where a young Jack Dorsey first worked for him. In 2009, after a $2,000 glass sculpture sale fell through because the buyer could not pay by credit card, McKelvey and Dorsey designed the original Square card reader and launched a payments company that would go public on the NYSE.
Beyond Square, McKelvey founded Third Degree Glass Factory, LaunchCode, and Invisibly, and donated $15 million to Washington University's engineering school. He has served as an independent director of the Federal Reserve Bank of St. Louis since 2017 and is the author of The Innovation Stack.
