From the outside, Andon Cafe looks like any other coffee shop.
Andon Labs' AI (Mona) lost 93.8% of a Stockholm cafe's $28k stake in 3 months via ChatGPT/GPT 5.5, failing at memory, scheduling, ordering. The experiment exposes why LLM agents can't handle real business ops: memory gaps, spatial reasoning failures, poor task coordination—benchmarks before enterprise deployment.
