Run Better Experiments With 1-On-1 Coaching Calls

Winning tests take time. To speed up the process I offer coaching to experimentation teams in the form of two calls per month. In this way, teams gain access to 344 experiments that make successful replications a lot easier. And in return we make GoodUI better as we share test results. Over the years we have accumulated highly predictive experiments from such companies as Microsoft, Reverb, Yummly, Thomasnet, Volders, Backstage, etc. If you apply and qualify, you can expect tap into this data to run better experiments while discussing any of the following:

Twice Each Month I'll Guide You On:

  • What To Test

    You'll receive top testing ideas based on what succeeded for other companies.

  • What To Measure

    You'll receive feedback and advice on how to structure and design your experiments.

  • How To Analyze The Results

    We'll look over your finished experiments to help you make the best decisions.

What You'll Need To Qualify:

  • Build & Run At Least One Test / Month

    You need to be able to build out and start at least 1 experiment per month. This implies you'll need to have existing experience in setting up a/b tests, a testing tool, and development resources.

  • Good Enough Traffic

    You need to have at least 50,000+ unique visitors and ideally 2000+ transactions per month to be able to detect the effects.

  • Sharing Experiments (Two To Start)

    Since we don't charge any fees for this, you'll be sharing test data with us. To start we'll ask for 2 experiments you already ran in the past. With your help we'll also be correcting GoodUI to improve its predictive accuracy.
