Has anyone tried in to run an AB test on Growthbook based on bucketing entities other than users? In our domain we have some cross-user interaction centred around other entity types, so it'd be more useful to randomise and measure based on these other entities instead of users. In theory we can still hash and bucket based on the entity IDs but I'm wondering if anyone knows what other hurdles we may come across? (I also notice sometimes Growthbook refers to 'units' and sometimes to 'users' so it isn't clear if other types of entities are supported)

Hi! You can absolutely randomize on any entity you want. While "user" is most common, you can use other units. Our docs/app often refer to users because it's most common, but it's something we're trying to update over time to always refer to experiment units. Internally, when we randomize, we usually do it on the organization id, so that everyone in the org gets the same variations.

that's great to know thanks ryan!
