SaaStr Details Its Vibe-Coded 'AI VP of Marketing' 10K: 14,230 Lines of Code, $257/Month, Two Agencies Quietly Fired

SaaStr·high signal

SaaStr published a deep breakdown of '10K,' its internally vibe-coded AI VP of Marketing running on Claude and Replit at 14,230 lines of code, which together with its AI VP of Customer Success ('QB') costs a combined $257/month. The agent refreshes ticket sales, drafts newsletters and tweets, builds pricing models, and snapshots GAAP financials daily — and in a companion post SaaStr says it silently displaced two outside vendors at $20K+ each. This is the clearest documented case yet of a media/events business replacing senior marketing headcount and SaaS tooling with a single self-built agent.
