● Publisher Partnerships: Build and manage direct relationships with premium publishers and media owners, including negotiating and managing PMPs and Programmatic Guaranteed deals. Identify new publisher opportunities aligned with advertiser demand and campaign objectives. Partner closely with Marketing and Sales to own the packaging and productization of inventory bundles, libraries, and a dedicated inventory go to market motion that sells inventory from and through us.
● Market Intelligence: Track trends in the programmatic supply ecosystem. Maintain knowledge of emerging inventory sources, CTV supply, and curated marketplaces. Provide recommendations on new supply partnerships or inventory channels.
● Internal Collaboration: Work closely with Ad Operations, Sales, and Product teams to align supply strategy with advertiser demand. Support troubleshooting of supply issues impacting campaign delivery. Collaborate with Sales in securing premium inventory deals for key clients.
