Start with one user
A specific first user makes the problem, workflow and distribution easier to test. “Everyone” cannot give you useful product evidence.

Make your first version smaller.
Describe the problem, target user and proposed features. The checker will separate a testable first scope from later ideas and prepare a brief you can copy or email.

How to use the result
An MVP is a test, not a small version of everything.
The score is a simple planning signal, not market validation. Its job is to expose scope and risk before those decisions become expensive.
Keep one outcome
The first version should prove that one meaningful outcome improves—not demonstrate every direction the product could eventually take.
Earn complexity
Accounts, payments, live data and AI can be necessary, but each should enter version one because the test requires it, not because mature apps have it.
Need a second pair of eyes?
Turn the brief into a realistic build plan.
Send the result to TechGnomo and start with the constraints, risks and next test—not a sales pitch.
