Stress Test

Good for pressure testing decisions before you commit to them. You feed it a plan or direction you're considering, and it comes back with potential failure modes, edge cases, and second-order effects you might not have thought through. Think of it as having someone play devil's advocate systematically rather than just nodding along. Most useful when the stakes are high or you're too close to something to see the holes. It won't make the decision for you, but it'll make sure you've actually thought it through instead of just running on confidence and momentum.

/executive-mentor:stress-test — Business Assumption Stress Testing

Command: /executive-mentor:stress-test <assumption>

Take any business assumption and break it before the market does. Revenue projections. Market size. Competitive moat. Hiring velocity. Customer retention.

Why Most Assumptions Are Wrong

Founders are optimists by nature. That's a feature — you need optimism to start something from nothing. But it becomes a liability when assumptions in business models get inflated by the same optimism that got you started.

The most dangerous assumptions are the ones everyone agrees on.

When the whole team believes the $50M market is real, when every investor call goes well so you assume the round will close, when your model shows $2M ARR by December and nobody questions it — that's when you're most exposed.

Stress testing isn't pessimism. It's calibration.
