Max Levchin, cofounder of PayPal and Affirm

Max Levchin is the cofounder and former CTO of PayPal. His stories from PayPal’s early days reveal that its methods for addressing security questions from the start can apply to the problems social media companies face today. Levchin started Affirm to do away with amoral loan practices; recently, Affirm allowed government employees who couldn’t work during the shutdown to take their time in paying back loans. Levchin values honesty and transparency, which serve as the foundations for his products.
