01Best for
Variant decisions: copy, flows, designs, packaging — before you spend traffic.
Output
A segmented verdict: winner overall and per segment, with margin and abstentions.
Best for
Landing pages, onboarding flows, feature framings, packaging variants.
Grounding
Variant order is randomized per persona — a position-bias guard, recorded with the result.
Anti-pattern
No post-hoc rationalisation — the hypothesis and success metric are stamped before exposure.
The loop
Freeze the variants
Every option is fixed before any persona sees it — a changed variant is a new test.
Stamp the hypothesis
One falsifiable bet and its success metric, recorded before exposure.
Force the preference
Randomized order per persona, then a forced choice with intensity — a genuine “torn” counts as an abstention.
Segment the verdict
Winner overall and per segment, with margins — then a red-team argues against the winner before you ship it.
02How it works
Runs through Lean / Jobs-to-be-Done.
A job is the outcome you buy; underneath, the run follows a proven framework and reaches for one move at a time. A/B Test runs through Lean / Jobs-to-be-Done, using head-to-head, prototype test, red-team along the way — and it won’t converge until the panel below has weighed in.
The formats
Coverage
At least 4 personas, spanning segment · current-alternative · buying-stage. Segment-diverse by design: the verdict is per-segment, so the panel spans every segment the variants could split — four personas minimum, no segment owning the panel.
