Statsig let's you slice results by user properties. Common examples of doing this include breaking down results by user's home country, subscription status or engagement level.
This typically requires running a custom query (from the Explore tab). You can now configure these properties to be pre-computed on the experiment setup page, under the advanced settings. It's also possible to configure team-level defaults for this - or pre-configure it on an experiment template.
This is now rolling out on Statsig Warehouse Native. See docs.
