# Stack Failure Drill

A fire drill for your revenue stack. Draw your go-to-market stack as a metro map (or pick a company size from startup to mega-corp, up to 250 tools), fail one tool for a few hours, and watch the leads queue. You'll see which departments get cut off, which service targets break, and how much pipeline is at risk.

- Runs entirely in your browser. Nothing is uploaded.
- Discrete-event simulation validated against closed-form queueing results (M/M/1, M/M/2, M/D/1 within 5%).
- Printable incident report, runbook (Markdown) and Slack digest.
