Fill in the four hypothesis fields
Target user, the change, expected behaviour, and the measure that would prove it.
MVP SCOPE
Feature Hypothesis Card
Create a compact card stating the target user, the change you'll make, the expected behaviour, and how you'll measure it.
- Uses your inputs in a transparent calculation
- Instant result with practical next steps
- No signup required
Planning guidance only. Validate important decisions with customer evidence and your delivery team.

How it works
We check testability
The measure is checked for a number and a timeframe, the two things that make a hypothesis actually testable.
Get your finished card
A single readable hypothesis statement is generated, ready to attach to the feature.

Frequently asked questions
Why does the measure need a number?
A measure without a number ('will improve engagement') can't be judged pass or fail later. A number gives you a clear target.
Why does the measure need a timeframe?
Without a timeframe, a hypothesis can be claimed 'still in progress' indefinitely. A deadline forces an honest check.
Is this the same as an experiment design?
It's a lightweight precursor. A full experiment design would add sample size, test duration, and statistical significance criteria.

Notion and Miro are general workspaces where a hypothesis card could be written by hand. MVPHub checks the hypothesis for testability automatically as you write it.
