What could kill your idea
The one thing most likely to sink it — and the cheapest way to check it, in two minutes.
Every idea rests on assumptions. One of them is the one that, if wrong, kills the whole thing. List yours, rate each on impact and how sure you really are, and this worksheet ranks which to test first.

Highest risk (impact 5 × uncertainty 4 = 20). Find the cheapest test that could prove it wrong before you build anything else.
Risk score = impact × uncertainty. A high-impact assumption you're very unsure about is the one to test before you build anything else.
The cheapest test that could prove an assumption wrong is worth more than months of building on top of it. For most assumptions that test is a handful of conversations with real potential customers.
This is the core of how Kasspian reads an idea — it names the killer assumption and the cheapest way to test it. Run your idea through the full version for a second opinion backed by real sources.

Common questions
What is a riskiest assumption?
It's the belief your idea depends on most that you're least sure about — the one that, if wrong, kills the whole thing. Risk score is impact times uncertainty, and the highest one is what to test first.
How do I find my riskiest assumption?
List the things your idea assumes are true, rate each on impact and how sure you really are, and the highest impact × uncertainty is the one to test before building. The worksheet above ranks them for you.
How do I test a risky assumption cheaply?
For most assumptions the cheapest test is a handful of conversations with real potential customers — far cheaper than building on top of a guess and finding out you were wrong later.
