Episode Description

What does it actually take to build something that has never existed before?

In this episode, Jim McKelvey, co-founder of Square (now Block), breaks down the real story behind building Square from scratch, not with a perfect plan, but through necessity, invention, and relentless problem-solving. 

Jim introduces the concept of the Innovation Stack, why innovation is rarely chosen willingly, and why copying “what worked before” fails when you’re solving a problem no one else has solved. He shares the moment Square felt real, the panic of Amazon launching a competing product, and the counterintuitive strategy that helped Square survive.

You’ll learn:

  • What the Innovation Stack is and why it protects companies from copycats
  • How Square started from a single lost sale and grew into a global company
  • What happens emotionally when you’re building something no one understands yet
  • Why copying best practices can fail when you’re solving a brand-new problem
  • Why mission-driven teams outperform money-driven ones over time

  • 05:30 The moment Square was born, one lost sale that changed everything
  • 10:00 Why the payments industry was designed to exclude small businesses

  • 31:00 Panic attacks, pressure, and the nervous system cost of building
  • 35:30 Copying vs innovating, and where founders get trapped
  • 47:00 Imposter syndrome, even after success
