MarkApp launched Pantheon's AI Agent Stack on 1 September 2025 as a suite of five active AI agents spanning CTV, mobile, and web. Pantheon is a contextual marketplace built on OpenRTB 2.6 with AI-driven automation embedded across the media lifecycle. The agent suite converts briefs into ready-to-activate media plans, enforces brand safety and contextual relevance, dynamically optimises pricing and allocations, adapts creative to devices and behaviours, and delivers predictive insights and cross-device intelligence. The platform supports seamless programmatic activation, targets higher engagement, reduced CPM volatility, and measurable business outcomes, operating globally at scale.
Campaign builder agent: Converts briefs into ready-to-activate contextual media plans. Brand safety and relevance agent: Guarantees campaigns run in secure, contextually appropriate environments. Real-time optimisation agent: Dynamically adjusts floor prices, geo allocation, and placements to improve engagement, viewability, and ROI. Creative intelligence agent: Tests and adapts creative variations to screen sizes, devices, and user behaviours.

With these agents working in unison, Pantheon ensures that advertisers achieve higher engagement, reduced CPM volatility, and measurable business outcomes across every screen. Sotiris Oikonomou, managing director at MarkApp, commented: "Pantheon represents the next stage of contextual advertising. By embedding AI at every stage of the media lifecycle, we are giving brands a smarter, safer, and more accountable way to scale across CTV, apps, and web.
