Questions

Straight answers.

What does preflight actually predict?

A likely performance tier — high, average, or low — based on comparison against historical campaign data, plus the specific risks and improvement opportunities driving that prediction.

Does it work on creative we made elsewhere?

Yes. Preflight evaluates any creative you're about to launch, regardless of who produced it.

How accurate is it?

Predictions are compared against live results on every campaign, and the model sharpens on your account's own data over time. We'll show you the track record in a demo rather than quote a blanket number.

Get Started

Stop paying to find out.

Bring a creative you're about to launch and we'll preflight it live.
