The small product validation loop

Most validation advice was written for funded teams shipping software. For a $19 digital product, the loop should fit in a week — not a quarter.

One promise, one buyer, one channel

Write the promise as a single sentence. Name the buyer in one line. Pick one channel where that buyer already pays attention. If you can't fit any of these on a sticky note, the product is too vague to test.

Ship the smallest believable version

A 12-page PDF. A 6-template Notion bundle. A 30-minute Loom walkthrough. The point isn't the format — it's that the smallest version still delivers the promise.

Then sell it for real money. Free downloads don't validate anything except your generosity.

Read the launch honestly

1. Did the channel show up?
2. Did the promise convert at the price you set?
3. Did buyers come back, refer, or ask for the next thing?

Three questions. Write the answers down before you start the next thing — that's what makes it a loop instead of a treadmill.
