Fast feedback and fixing role-fit issues

Keller Cliffton is the co-founder and CEO of Zipline, the world's largest commercial autonomous delivery system, which today serves 5,000 hospitals across multiple countries and saves an estimated 17,000 lives per year. In this episode, Keller breaks down his extreme hiring philosophy that has powered Zipline for over a decade.

In today's episode, we discuss:

• Why Zipline hires teenagers over PhDs
• Why the best startup employees are "heat-seeking missiles for pain"
• The 5 leadership attributes Zipline has never shared publicly
• The brutal firing advice that shaped Keller’s leadership
• How Rwanda’s health minister changed Zipline’s trajectory
