AppLovin is ingested today as a Fivetran custom dataset in which every advertiser account for a tenant is merged into a single pooled source, with no native breakdown by account or brand. Multi-brand advertisers (e.g. Nysonian running Nobl and Flo on separate AppLovin accounts) cannot split spend, impressions or custom metrics by brand out of the box. The only workarounds today are filtering on Campaign Name patterns or building a Custom Dimension, both of which depend on a naming convention the customer controls in AppLovin and break as soon as a campaign is renamed. Request: expose the source advertiser account (datasource) as a first-class dimension on AppLovin explores, tiles and custom metrics, equivalent to Account Name on Google Ads or Meta.
