Jim McKelvey was a glassblower when he created the idea for the payment platform Square (now Block, Inc.). He was furious that he couldn’t accept certain credit cards as an artist and contacted a former colleague and Twitter co-founder Jack Dorsey to solve the problem. What took three weeks to build became a three-year journey of creating Square into a banking disruptor inspired by McKelvey’s frustrations. In the 15 years since McKelvey teamed up with Dorsey, Square has grown into a billion-dollar business and beat the world’s best company at absorbing startups—Amazon.  Listen to Nathan and Jim discuss: Hitting it off with Dorsey when he was his summer intern Realizing how many laws they were breaking with Square Convincing the banking industry to accept Square  Taking on Amazon and winning Researching unbeatable companies throughout history  Why he wrote the book The Innovation Stack How to pitch a product Why it’s better to copy than innovate His new foundr course Plus, excerpts from our live community event  And much more innovation advice...
