The conversation covers how Stripe operationalizes its 'be meticulous in your craft' principle through friction logging, UX reviews, and walk-the-store sessions. Singleton details Stripe's remarkable infrastructure achievement: 16.4 daily deployments to their core API with 99.999% uptime, enabled by automated testing, staged rollouts, and continuous learning from incidents.
