Pre-Mortem for Founders

Most startups don't fail because of bad luck. They fail because of an assumption nobody said out loud — until it was too late to fix.

The pre-mortem flips the usual planning question. Instead of asking "will this work?" — a question your own optimism will happily answer "yes" to — you assume the plan has already failed, six months from now, and work backward to find out why. It's a technique used by cognitive psychologist Gary Klein and praised by Nobel laureate Daniel Kahneman as one of the most practically useful decision tools in modern risk thinking. This guide adapts it into a repeatable, five-step system built specifically for founders.

Inside, you'll find:

• The five-step Pre-Mortem framework — Autopsy, Verdict, Rebuild, Adversary, Tripwire — ready to run before any high-stakes call
• How to apply it to fundraising, launches, pivots, and key hires, with the specific failure patterns each one attracts
• A worked, real-world-style example showing the framework catching a flawed pricing assumption before it costs a single dollar
• The most common mistakes founders make running this exercise — and how to avoid turning it into theater
• A system for turning every risk into a dated, owned monitoring tripwire — not just a list of worries

This is for founders who are done choosing between blind optimism and paralysing risk-aversion, and want a third option: a structured way to look failure in the eye before it costs them their runway, their team, or their company.

Every risk this process surfaces is treated as a solvable problem, not a reason to freeze. Open the book, pick your next high-stakes decision, and run your first pre-mortem before you need one.
