Mediaplus Group Appoints Costin Mihaila as Global Chief Market Officer

The Mediaplus Group, the agency arm of the Serviceplan Group and Europe’s largest independent media agency, has officially announced a significant leadership expansion. Costin Mihaila is set to join the organization as the new Global Chief Market Officer, a strategic role designed to accelerate the agency’s international growth and unify its market presence across global territories.

Strengthening Global Market Presence

Mihaila, a seasoned executive with an extensive background in international media strategy, will assume his new responsibilities in mid-April 2026. This newly created position underscores Mediaplus Group’s commitment to scaling its operations beyond its strong European footprint. By centralizing market strategy under a dedicated Global Chief Market Officer, the agency aims to streamline its service delivery for multinational clients who demand consistent, data-driven media solutions across disparate geographical regions.

The appointment comes at a pivotal time for the media landscape, as agencies navigate the complexities of digital transformation, the shift toward first-party data, and the increasing demand for integrated brand experiences. According to the Serviceplan Group, Mihaila will report directly to the global leadership team, focusing on optimizing the group’s market entry strategies and fostering synergy between local offices and the global headquarters.

Strategic Implications for the Agency

The decision to appoint a Global Chief Market Officer is not merely an administrative shift; it is a tactical move to maintain competitiveness against global holding companies. Mediaplus has consistently focused on its “House of Communication” model, which integrates media, creative, and technology under one roof. Mihaila’s mandate will likely involve:

• International Scaling: Coordinating efforts to expand the group’s footprint in key growth markets.
• Operational Efficiency: Standardizing media buying and planning processes to ensure client expectations are met regardless of location.
• Talent Integration: Bridging the gap between the Munich-based headquarters and international branches to ensure a unified agency culture.

Industry Context and Future Outlook

The media agency sector is currently undergoing a period of consolidation and refinement. As brands prioritize efficiency and transparency, independent groups like Mediaplus are finding success by offering agility that larger, legacy networks often struggle to replicate.

By bringing in specialized leadership for the Global Chief Market Officer role, Mediaplus is signaling to the market that it intends to prioritize long-term international development. This move is expected to bolster the agency’s pitch capabilities and enhance its ability to retain global accounts that require centralized management and decentralized execution.
