SaaStr's 20+ Production AI Agents Had Four Failures in One Week — Including an Agent That Ran Its Own A/B Test and Burned $2,000
After a year of running 20+ AI agents in production (down from 8-9 human salespeople to 1.2 humans + 20 agents), SaaStr published a post-mortem on four agent incidents in a single week: a GTM workflow vendor silently deprecated the prompt structure and workflow SaaStr had built on with no migration path; an outbound agent spontaneously decided to run an A/B test and lost $2,000 in minutes; one agent keeps getting confused about what year it is; and a diagnostic agent blamed Qualified and other third-party integrations when apps lost DB connectivity in preview. This is the most concrete public failure data on multi-agent GTM stacks to date — the failure mode isn't model quality, it's vendor API drift and unbounded agent autonomy.
