How the idea validation board works
Loop helps you replace guesswork with evidence, one small test at a time. Here's the full loop from idea to decision.
1. Name the assumption
Every test starts with the risky belief you're actually checking, plus a small method for checking it and a success criteria you set before you start.
2. Start the test
Move a draft test to active once you begin running it in the real world — talking to users, shipping a landing page, or running an experiment.
3. Log evidence as it happens
Add quotes, observations, and data points to the test as you gather them. Each note is timestamped so you keep an honest trail.
4. Decide: continue, revise, or stop
When you have enough signal, make the call. Add a short reflection so future-you remembers the reasoning, then move to the next idea.
Continue
The evidence supports your assumption. Keep building on this idea.
Revise
You got a partial or mixed signal. Adjust the idea or method and run another small test.
Stop
The evidence doesn't support it. Shelve the idea and protect your time for the next one.
Frequently asked
What counts as a good assumption to test?+
Pick the riskiest belief your idea depends on — usually about whether someone wants it, will pay for it, or will actually use it. If that belief were false, your idea would fall apart.
How small should the validation test be?+
Small enough to run in a day or two: a handful of interviews, a landing page, a manual concierge version, or a single outreach campaign. The goal is a fast, honest signal — not a full build.
When should I move a test from draft to active?+
As soon as you're actually running the experiment in the real world. Draft is for tests you've planned but haven't started collecting evidence for yet.
What's the difference between evidence, observation, and data notes?+
Evidence is something someone said or did that directly speaks to your assumption (like a quote or a purchase). Observation is a pattern you noticed. Data is a number or metric you tracked.
What happens when I choose continue, revise, or stop?+
The test is marked decided and locked with a timestamp and your reflection. You can always reopen it later if new evidence changes your mind.
Where is my data stored?+
Everything — your workspace, tests, and notes — is saved in this browser's local storage on this device only. There is no account, server, or sync. Clearing your browser storage or using a different device/browser will not show the same data.
