A/B testing just got a lot easier

To truly be data driven you need to test everything. To do that, it needs to be fast, easy, and reliable. With Unstack, setting up a test is as simple as click, click, launch.

AB Testing

Behind the scenes, data science is at work crunching numbers to determine a winner. Once a winning version is declared Unstack publishes the winner for you automatically.


When we decided to build A/B testing we wanted to approach it in a way that would make it systemically useful. It had to be easy, powerful, and reliable. Our A/B testing platform is just that. I use it myself and have 20+ tests running on Unstack at any given moment.
