ID Resolution++

A common problem in experimentation is trying to connect different user identifiers before or after some event boundary - most frequently signups. This often involves running an experiment where the unit of analysis is a logged out identifier, but the evaluation criteria for the experiment is a logged-in metric (e.g. subscription rate, or estimated lifetime value).

Statsig has upgraded our ID resolution solution to handle multiple IDs attached to one user. ID resolution. In addition to the strict 1-1 mapping that we already support, we now offer first-touch mapping to handle 1-many, many-1 and many-many mappings between different ID types. This is extremely flexible and enables use cases like:

• handling logins across multiple devices

• mapping users to metrics from different profiles or owned entities

For more information about this feature, check out the documentation. This option is available to all Statsig Warehouse Native experimenters!
