AGENT + HUMAN OPS: HOW AI IS CHANGING ROLES AND WORKFLOWS AT BREX

Summary from the TLDR Founders newsletter

Brex's CTO built an internal AI platform that lets any employee spin up agents in minutes, turning the company's COO's operations team from people managers into agent managers. The shift is radical - disputes that took 3 hours now take 3 seconds, AI does 100% of quality assurance on all interactions, and over 50% of customer support is fully automated. Most L1 roles managing basic tasks are gone, replaced by L2s who now prompt engineers and coach AI instead of coaching humans. Brex even changed its hiring to test AI fluency with case studies where candidates must show their prompts, not just results, because it believes operations can be 5-10x more efficient when teams have their own automation.
