Hypothesists · The App for Shopify

Your store, under instruments.

The only split-testing app that measures your store like a business: CVR, AOV, and LTV, always on, whether or not an experiment is running. One app replaces the stack.

Pillar One

The Observatory

Most testing apps only measure while a test is running. The Observatory measures your store continuously; experiments borrow its instruments, not the other way around.

LTV as a curve, not a numberCohort value at Day 0, 30, 60, and 90, computed from your real order history and kept current by webhooks.
Breakeven against CACEnter your blended acquisition cost and see exactly where the cohort curve crosses it. Ad-platform connections are on the roadmap.
Refund-adjusted truthEvery revenue metric available gross and net of refunds. Refund rate is a first-class dial, not a footnote.
Drill down on everythingAny dial, by any segment, over any date range. UTM parameters, referrer, device, geography, landing page, first order or fifth.
The attribution survey"How did you hear about us?" on the Thank You page, joined against UTM data. Self-reported truth beside click-tracked truth.
The anomaly sentinelAn alert when a dial moves beyond expected variance, before you would have noticed. Plus a Weekly Reading every Monday.

Pillar Two

The Laboratory

A full experimentation engine, run with the discipline the industry skips. Test theme templates, prices, and every widget in the app, in one click.

The hypothesis is mandatoryNo experiment launches without a falsifiable statement: what changes, what you expect, and why. The form is the philosophy.
No peeking, enforcedDuration and sample size are pre-registered. Results stay sealed until the run completes. Evidence, not anecdote.
Verdicts on the whole journeyEvery test is scored on CVR, AOV, refund rate, and cohort value together. A variant that lifts clicks but raises returns gets flagged, not celebrated.
The refund-window re-verdictExperiments automatically re-evaluate after the refund window closes. Wins that did not survive get demoted, in writing.
The LedgerA permanent, searchable archive of every hypothesis, run, and verdict. Your store’s institutional memory, compounding with every cycle.
Flywheel modeChoose your strategy: recycle margin aggressively into acquisition, or hunt maximum return per dollar. Verdict weighting follows your goals.

Pillar Three

The Instruments

The conversion tools you are paying five other apps for, rebuilt extension-native, styled to your theme, and A/B testable in one click. That last part is the point: your shipping bar threshold, your bundle discount, your upsell offer, all of it becomes an experiment instead of a guess.

The clock is real
August 26, 2026

Shopify removes legacy checkout scripts for every non-Plus store. The upsells, bars, and tracking pixels built on old script tags stop working. Everything in this app is extension-native, so the deadline is someone else’s problem.
