SaaStr·medium signal

SaaStr's AI VP of Marketing called '10K' is a 14,000+ line, 370+ commit agent built on Replit using Claude Opus. It runs daily standups, designs every campaign, synthesizes Salesforce data and vendor APIs into a live six-month plan, and flags trending-wrong metrics on Day 2 instead of Day 60. Monthly Replit bill: $94.51. It drove SaaStr to its first $10M revenue year. SaaStr also reported killing a $4K/year SaaS tool in 60 minutes with a custom agent. This is the most detailed public documentation of a company replacing traditional marketing operations with a custom AI agent at trivial infrastructure cost.
