MarkApp has announced a strategic integration with Nexxen, expanding global connectivity across both supply and demand through MarkApp’s Harion DSP and Pantheon SSP. 

The collaboration strengthens MarkApp’s ability to support advertisers, agencies, publishers, developers, and CTV partners with more efficient access to omnichannel programmatic opportunities across web, mobile app, and connected TV environments. At a time when the industry is moving toward cleaner supply paths, privacy-first activation, and more accountable media infrastructure, connectivity between trusted technology platforms has become a critical driver of performance. 

The partnership brings together MarkApp’s infrastructure-led programmatic ecosystem with Nexxen’s unified advertising technology platform. Nexxen operates across demand-side and sell-side technology, with capabilities spanning data, advanced TV, planning, activation, monetisation, measurement, and optimisation. For MarkApp, this creates stronger routes for both demand activation and supply monetization at global scale. 

Through Harion DSP, MarkApp advertisers and trading partners can benefit from expanded access to premium omnichannel inventory, including CTV, mobile app, and web environments. The integration supports more scalable campaign execution, improved reach, and stronger alignment between buying objectives and high-quality supply. 

Through Pantheon SSP, MarkApp’s supply and publisher partners gain access to broader demand connectivity, helping them unlock new monetisation opportunities while maintaining focus on quality, transparency, and contextual intelligence. Pantheon is designed to enrich and optimise bid requests before auction execution, supporting privacy-first monetisation without over-dependence on third-party identifiers. 

The strategic value of the partnership sits in the connection between supply quality and demand efficiency. Programmatic growth is no longer defined only by access to more inventory. It is increasingly defined by the ability to activate the right inventory through cleaner paths, stronger signals, and technology that can perform across fragmented digital environments. 

"As the programmatic ecosystem becomes more complex, partnerships that improve connectivity, transparency, and execution quality are essential," said Sotiris Oikonomou, managing director at MarkApp. "Our collaboration with Nexxen strengthens both sides of our infrastructure, helping advertisers access premium omnichannel opportunities while giving supply partners stronger demand routes across global markets."

The announcement reflects broader market momentum around supply curation, CTV growth, AI-driven optimisation, and privacy-first media buying. Advertisers are looking for more control over where budgets are deployed, while publishers and content owners are seeking monetisation models that protect value and reduce inefficiency. In this environment, full-stack connectivity is becoming a strategic advantage. 

MarkApp’s product ecosystem is built around three interoperable platforms: Pantheon, its proprietary contextual SSP; Harion, its cross-device DSP; and MarkDash, its reporting and operational intelligence layer. Together, they support campaign execution, supply monetisation, performance visibility, and business control across web, app, and CTV. 

The integration with Nexxen reinforces MarkApp’s position as a global ad tech infrastructure company focused on performance, transparency, and premium supply. It also supports the company’s broader mission to help partners navigate the next phase of programmatic growth with stronger technology foundations. 

As media investment becomes more fragmented across screens, platforms, and environments, the industry will increasingly reward infrastructure that connects supply and demand with greater precision. The MarkApp and Nexxen partnership is a step in that direction: global, omnichannel, and built for a more accountable programmatic market.
