MarkApp, a global ad tech company operating across web, mobile app, and CTV environments, today (21st January, 2026) announced the launch of Harion DSP, its new omnichannel demand-side platform (DSP) designed for brands and agencies executing both branding and performance strategies within a unified buying environment. 

Harion DSP addresses the growing complexity of modern media buying by connecting full-funnel objectives into a single, outcome-driven platform. Built to operate seamlessly across CTV, mobile app, and web inventory, Harion enables advertisers to execute awareness, consideration, and performance campaigns with consistent control over reach, frequency, and measurable results. 

The platform combines advanced audience activation, cross-device retargeting, and real-time optimisation to support high-impact use cases, particularly for retail, e-commerce, and performance-led advertisers. Harion supports CPM, CPC, and CPA buying models, allowing agencies and brands to align media strategy directly with business KPIs such as ROAS, CPA, and lead generation. 

By consolidating brand and performance buying into a single workflow, Harion reduces operational friction while increasing transparency and accountability. Advertisers benefit from unified campaign execution across screens, while agencies gain the flexibility to manage diversified client objectives without relying on fragmented tools or disconnected platforms. 

Sotiris Oikonomou, managing director at MarkApp, said: "Harion DSP was built to reflect how advertisers actually buy today. Brands no longer think in silos between performance and branding, and neither should their technology. Harion connects these strategies into one omnichannel platform focused on outcomes, scalability, and measurable growth." 

Harion DSP is designed for scale, supporting multi-market deployments, complex audience strategies, and evolving performance goals. Its launch marks a significant step in MarkApp’s product roadmap, reinforcing the company’s focus on delivering infrastructure that combines strategic flexibility with operational efficiency.
