For agencies
Your outbound clients want channels you cannot currently source, and your competitors are pitching the same three platforms. Mammoth supplies the differentiated supply layer without competing for your mandate.
Last reviewed
Chinese agencies use Mammoth as a supply-side enablement layer: it provides access to global premium inventory that the agency sells and plans against, while Mammoth handles media owner relationships, cross-border contracting and trafficking. The agency retains the client relationship, the plan and its margin structure.
Where it breaks
Outbound pitches converge because every agency is sourcing from the same accessible supply. Without a route into premium audio, CTV, broadcaster and creator inventory, differentiation collapses into buying efficiency claims on identical platform inventory.

What you get
01
Access to premium audio, connected TV, broadcaster and creator supply sourced through Mammoth's direct media owner relationships, available to plan against without you contracting each publisher yourself.
02
Mammoth does not pitch your clients or compete for planning and buying mandates. It sits on the supply side of your business, which is what makes the relationship workable rather than adversarial.
03
Contracting, insertion orders, trafficking, settlement and reconciliation with international media owners are handled by Mammoth, removing the operational overhead that usually makes premium outbound uneconomic.
04
Where you already operate a trading desk, supply is made reachable inside the systems your traders use, so outbound premium buying does not require a parallel workflow.
05
Third-party ad serving and independent verification through the ReachMax stack, producing measurement documentation that survives client scrutiny on both sides of the border.
