Marketing Measurement Finally Done Right

Geo-holdout testing, unlimited access, integrated with your forecast.

There are three questions at the center of creating a predictable, profitable ecommerce growth plan …

  1. What’s my optimal total budget to maximize profit?
  2. How should I split that budget across channels for the best incremental lift?
  3. What’s the daily media plan and profit forecast?

… and no single platform or service provider has a solution for all three, until now.

Geo-Holdout Incrementality Testing

The Gold Standard of Measurement

Incrementality testing is the gold standard for understanding what's truly working in your media mix. But until now, it's been prohibitively expensive or siloed from your strategy.

We built our own tool — fully integrated into Statlas so we could:

  • Run unlimited geo-holdout tests for any client
  • Validate impact by channel, campaign, or cohort
  • Make allocation decisions with 90%+ confidence

Why We Built It

Accurate, Affordable Incrementality Testing

Every ecommerce brand needs to use geo-holdout testing to succeed in today’s economic landscape.

Because we already have the platform, Statlas, the data, and the people in place, we can deliver high-confidence incrementality test results at a fraction of the cost.

Unlike standalone geo-holdout tests from other measurement firms that stop at insights, we go further …

We integrate those results directly into your growth strategy and business forecast.

So you don’t just get answers. You get direction.

Here’s how it works …

1. Market Selection
