Hi Vrinda!

To isolate an audience based on a randomized split, you’d build journey steps as in the first example below. 

The branches of your splits would reflect as 85% and 15% - each generating their own audience keys. 

Once you save the journey, you should be able build an audience based on those keys as in the second screenshot below.

oh that is quite helpful...thank you so much!

Welcome ​@Vrinda Aggarwal!

​@Vrinda Aggarwal - Were you able to achieve what you were aiming to do? I’m adding a follow up to my answer above for additional clarity as the workflow has changed recently in V2. 

This key is unique to the destination step and an audience can be created but dependent on the action.  So to add profiles to an audience, you’d have to add an Action List Destination that will be synced to according to the Destination Key. Two ways of doing so: 

1. Utilize the 'Activity Feed' tab that basically is a list of step transition events that each profile went through in the Journey. This listview can be filtered down per Step / Branch
2. Add a Destination step which will emit a custom event on the profile that you can build an audience for

Hey Chauntel, I tried a few things but it didn’t work...I will try the idea that you gave.
However, right now I have facing issues with destination also with one capability not built in Segment yet. So my project is kind of stalled.
