Turn your business idea into a series of small, affordable experiments that replace guesswork with evidence.
1 — Describe Your Idea
Write it the way you'd explain it to a friend — the problem, who has it, what you'd build or offer, how you'd make money. The more concrete you are, the sharper the stress-test. Don't worry about structure; the framework does the sorting.
The richer the description, the more specific your assumptions and experiments will be.
Takes about 15–30 seconds.
Stress-testing your assumptions…
Extracting assumptions, scoring risk and evidence gaps, and sequencing your experiments.
2 — The Idea, Sharpened
3 — Assumption Map
Every idea is a stack of beliefs. Here they are, sorted by the three risks that sink most ventures. Each carries a Risk score (how fatal if it's wrong) and an Evidence Gap (how little you actually know) — multiplied into a priority out of 25.
4 — What to Test First
Ranked by risk × evidence gap. The assumptions at the top are the ones most likely to be wrong and most likely to kill the idea — your kill-shots. Start there.
5 — Your Testing Plan
An ordered sequence drawn from the 44 experiments in Testing Business Ideas — cheapest, fastest evidence first, escalating only as each assumption survives. For each one: how it works, how to run it for this idea, what it costs, and the signal that means "keep going."

Experiments run from cheap, fast, and weak (Discovery) to costlier but stronger (Validation). The framework picks from these and orders them for your riskiest assumptions.
