Dentsu Group Inc.

Dentsu Group operates a centralized technology platform, Merkury, which provides a unified identity and data layer across its agency network. Each leadership brand — Dentsu Creative, Carat, iProspect, dentsu X, and Merkle — retains independent client relationships but shares this data infrastructure, enabling end-to-end experience transformation (EX) and business transformation (BX) delivery.

Merkury is Dentsu's patented person-based identity and data platform. It allows enterprise brands to identify customers in real time and deliver hyper-personalized experiences across the marketing ecosystem. The platform is positioned as a distinguishing asset enabling cross-channel engagement and measurement.

Dentsu Group serves clients across multiple industries including consumer goods, technology, financial services, healthcare, and automotive. Its client roster includes leading global organizations, though specific client names are generally not disclosed publicly outside campaign case studies.

Dentsu Group operates as a single integrated corporate entity, not a traditional holding company. Its agency brands maintain their own market identities but share centralized functions including technology, data, and strategy — a structure designed to deliver consistent transformation outcomes while preserving brand equity.

Dentsu Group reports a presence in over 145 countries and regions, with a particularly strong footprint in Japan, North America, and Europe. The company is headquartered in Tokyo, Japan, and was founded there in 1901.
