Experiment ledger
BetaMarketers Lab
A ledger for the test, written before the account spends.
Why we built it
Tests die in decks. The belief, the prediction, and the campaign name never meet, so the next test starts from zero. Marketers Lab makes you write the hypothesis down before the account is allowed to “learn.”
Who it’s for
In-house growth leads and the person who actually names the campaigns.
What it does
You record the hypothesis and the predicted movement before spend. Campaign names carry the link, so the ad account can be read back into the experiment that produced it. What you believed, what you predicted, and what the account did stay in one row.
Where AI shows up
A model can draft the test. It doesn't get to move the number until a prediction is frozen. Marketers Lab is where that suggestion has to land. The product doesn't write the ads.
Use cases
- Freeze a creative or offer test before the account starts spending
- Join a live campaign name back to the hypothesis that justified it
- See which predictions were wrong, as well as which ads spent
Lab note
Campaign names should carry the hypothesis
If the ad account can't be read back into the experiment that produced it, the learning dies in a spreadsheet.
