I let Opus 5.5 run a business on its own for a week: €0.00, 245 dead ideas, and its AI manager ghosted the team on day 1

A user tasked a "farm" of Opus 5.5 agents with generating revenue over a week. The AI agents, running on Claude accounts, explored 245 business ideas, ultimately pursuing a German e-invoice validator. This product was developed and advertised, attracting 68 visitors and checking 6 real invoices, but generated €0.00 in revenue. The project's progress and the AI manager's early disengagement were documented, with the farm's code made open source.

This report uniquely details a week-long, real-world business operation run entirely by Opus 5.5 agents, unlike typical theoretical discussions of AI business capabilities.
