Decidi for founders

Run the pre-mortem before reality runs it for you.

Stress-test your work Chat free · no sign-up, no card

Stress-test the plan, the pitch and the assumption your whole company rests on — so the only surprises left are the ones you chose to take.

Why founders use it

Run a brutal pre-mortem on the strategy: assume it failed in eighteen months, then work backwards to why.
Have an independent panel hunt the load-bearing assumption nobody on the team will challenge to your face.
Get the investor’s real objection rehearsed before the meeting — the one that ends the conversation, not the soft ones.
Pressure-test unit economics and the go-to-market so the model isn’t just a hope spreadsheet.
Hear the hire/fire, raise/bootstrap, build/buy call argued from every seat, not just the one you already lean toward.
Replace the echo chamber — independent models won’t flatter the founder the way a single agreeable chatbot will.

Stress-test before you ship

The strategy — the pre-mortem on why it could fail
The core assumption the business depends on but nobody questions
Unit economics and the path to a real margin
The pitch deck — the slide an investor stops you on
Go-to-market — whether the channel actually scales
The big irreversible call: raise, pivot, hire, or hold

A worked example — the pivot you can only afford once

Say you have nine months of runway, flat growth, and a plausible pivot into an adjacent market that two large customers have hinted they would pay for. Your team is split, your investors are waiting for a plan, and every week of deliberation costs a week of runway.

The Pre-Mortem Analyst opens by assuming the pivot failed and works backwards to the likeliest causes — usually the two customer hints turning out to be politeness rather than budget. The Sceptical Investor prices how the pivot reads at your next raise, the CFO turns both paths into months-of-runway arithmetic, and the Devil’s Advocate argues the unpopular case (often: the current product is under-distributed, not wrong). Because each member sits on a different model, you get genuine disagreement instead of one AI agreeing with whoever framed the question. The moderator commits to a recommendation with a confidence level, and the roll call shows you exactly who dissented and why.
