The world’s biggest marketing and advertising Gcc holding companies now run a meaningful share of their global operations out of India. Here are the centres doing that work, and what it says about where the industry is headed.
Marketing and advertising’s version of the GCC story looks different from healthcare or BFSI. The industry itself has consolidated to a handful of global holding companies, WPP, Omnicom (now including IPG), Publicis Groupe, Dentsu, and Havas, and each now runs a substantial India operation spanning creative production, media, data and analytics, and technology delivery. Alongside them, captive in-house agencies like Cheil India (Samsung’s global network) and research and measurement firms like Nielsen round out a market that has moved well past “back-office support” into genuine strategic delivery.
Marketing and advertising GCCs in India do not map cleanly onto the “GCC” template built by engineering-heavy sectors like healthcare or BFSI. Much of the industry’s India workforce sits inside full local agency operations serving Indian clients directly, not purely captive back-office functions. But a genuinely distinct and fast-growing layer does fit the classic GCC mould: dedicated India delivery centres built by global holding companies and brand-owned agencies specifically to serve markets and clients outside India, spanning creative production, data and analytics, media operations, and technology.
That layer has grown quickly, and consolidated even faster. The 2025 Omnicom-IPG merger alone folded two of the industry’s largest India Global Capability Centre into one roughly 7,000-person operation. Here are the centres defining this space.
Leading Marketing and Advertising GCCs in India
Cheil India
Overview
Cheil Worldwide is Samsung’s global advertising and marketing network, headquartered in Seoul and operating in 45-plus countries.
India Presence
Cheil India, headquartered in Gurugram, serves as Cheil Worldwide’s regional hub for South-West Asia, with 700-plus employees across five offices nationally.
What Their Team Does
Strategic planning, creative advertising, digital marketing, brand activation, and retail marketing, ranking among the top five advertising agency networks operating in India.
Why It Matters
As Samsung’s in-house global agency, Cheil India’s output feeds directly into one of the world’s largest consumer electronics brands, well beyond a typical client-agency relationship.
Cheil India is among the organizations that have chosen Synq.Work for workplace solutions, reflecting the growing importance of flexible and innovation-driven workspaces for global marketing and advertising GCCs.
Publicis Groupe
Overview
Publicis Groupe – A nearly 100-year-old global marketing and communications group, and one of the industry’s largest holding companies by revenue.
India Presence
India’s largest marketing GCC footprint by far: Publicis Sapient’s delivery network spans six cities, Publicis Groupe Data runs 3,200-plus specialists, and Epsilon India adds another 3,000, all under a shared services structure supporting more than 100 countries.
What Their Team Does
Digital business transformation, data engineering, AI and machine learning, software engineering, media operations, and core business services spanning finance, legal, and procurement.
Why It Matters
Nearly half of Publicis Sapient’s global workforce now sits in India, making it less an offshore support function and more a genuine centre of gravity for the group.
WPP (Kantar, GroupM & Ogilvy)
Overview
WPP – The world’s largest advertising and marketing holding company, built around research (Kantar), media investment (GroupM), and creative networks including Ogilvy, VML, and Grey.
India Presence
Kantar IMRB, founded in 1970 and headquartered in Mumbai, is one of India’s oldest and largest market research firms. GroupM India runs seven media agencies including Mindshare and Essence, and WPP has formally unified Kantar and GroupM in India into a combined analytics practice. Ogilvy, WPP’s best-known creative brand globally, also runs full-service offices in Mumbai, Gurgaon, and South India, though these function primarily as market-facing agency operations serving Indian and regional clients directly, rather than a captive delivery centre in the Kantar or GroupM sense.
What Their Team Does
Syndicated market research, brand and communications analytics, media planning and buying, and data-driven marketing services across categories, alongside Ogilvy’s full-service creative and advertising work for Indian and global brands.
Why It Matters
Kantar IMRB built India’s first household consumer panel and first television audience measurement system, giving WPP’s India operation genuine institutional depth, not just delivery scale. Ogilvy’s presence adds brand recognition and creative capability, even though its India footprint is structured differently from the group’s shared-services operations.
Omnicom Global Solutions
Overview
Omnicom Global Solutions – Following its 2025 acquisition of Interpublic Group, Omnicom now operates three global creative networks, BBDO, TBWA, and McCann, alongside a unified media and data operation.
India Presence
Omnicom Global Solutions (OGS) India absorbed IPG’s roughly 2,200-person India GCC into its existing 4,500-person operation, creating a combined workforce of more than 7,000 spanning media, data, technology, healthcare, and business operations.
What Their Team Does
Media and data services, martech, engineering support for Omnicom’s proprietary Omni platform, and healthcare-specific marketing operations.
Why It Matters
This is the clearest evidence of industry-wide consolidation reaching India directly: two of the “Big Six” holding companies became one, and their India GCCs were merged into a single operation rather than run in parallel.
Dentsu
Overview
Dentsu – Founded in 1901, Dentsu is the only major Asian holding company among the global “Big Six,” combining Japanese operational discipline with Western creative practice.
India Presence
Dentsu Creative operates three creative hubs across Mumbai, Bengaluru, and Gurugram. In July 2025, Dentsu launched Dentsu Lab India, joining a global innovation network that includes only Tokyo, London, and Warsaw.
What Their Team Does
Integrated creative, media, and customer experience management, plus experimental R&D spanning AI, immersive technology, and human-centred design through Dentsu Lab.
Why It Matters
India is one of only four cities globally hosting a Dentsu Lab, placing it alongside Tokyo and London in the company’s innovation hierarchy rather than treating it as a delivery-only market.
Accenture Song
Overview
Accenture Song – Accenture’s marketing, experience, and commerce arm, competing directly with traditional holding companies through a consulting-first approach to brand and data work.
India Presence
Bengaluru is Accenture’s largest India hub, with additional operations across Hyderabad, Pune, Mumbai, Gurgaon, Chennai, and Kolkata supporting technology and digital transformation work.
What Their Team Does
Data integration, digital experience design, and marketing technology delivery, positioned around client empowerment and consulting-led data strategy rather than traditional creative-first agency work.
Why It Matters
Accenture Song represents a structurally different competitor to the traditional holding companies, one built from a technology consultancy outward into creative, rather than the reverse.
Nielsen
Overview
Nielsen – The global standard-setter for audience measurement and consumer panel data, historically the backbone of how media investment gets valued worldwide.
India Presence
Nielsen runs a Mumbai-based GCC operation, part of the city’s dense cluster of media and data-focused capability centres alongside WPP and Publicis Sapient.
What Their Team Does
Data processing, analytics, and measurement infrastructure supporting Nielsen’s global audience and consumer panel products.
Why It Matters
Even as first-party data and retail media reshape the measurement landscape industry-wide, Nielsen’s India centre remains central to how the underlying data infrastructure gets built and maintained.

Why India Leads in Marketing and Advertising Delivery
- Data and analytics depth. India’s engineering talent base translates directly into marketing data science, from Kantar’s research infrastructure to Publicis Groupe Data’s 3,200-plus specialists.
- Cost efficiency at scale. Real, and part of why nearly half of Publicis Sapient’s global workforce now sits in India, but no longer the primary justification for the largest centres.
- Consolidation-driven scale. The Omnicom-IPG merger shows how holding company consolidation flows directly into India GCC scale, not just global headcount.
- Creative R&D credibility. Dentsu Lab India’s inclusion alongside Tokyo and London signals India competing on creative innovation, not just execution capacity.
- Institutional research history. Kantar IMRB’s decades-long track record building India’s original market research infrastructure gives WPP’s centre a depth that newer GCCs cannot replicate quickly.
Where This Is Heading
Consolidation among the global holding companies is likely to keep compressing headcount into fewer, larger India operations rather than spreading it across more standalone centres. The Omnicom-IPG integration is the clearest recent example, and further holding company restructuring would likely follow the same pattern in India specifically, since real estate, technology, and support functions are exactly where integration savings get captured first.
AI adoption is reshaping the work itself faster than in most other GCC sectors. Content generation, campaign personalisation, and media optimisation are increasingly AI-assisted, shifting India teams toward orchestration, quality control, and the strategic judgment calls that generative tools cannot yet make reliably.
Brand-owned in-house agencies, the Cheil India model, are likely to keep growing as more global brands bring marketing capability in-house rather than routing everything through independent holding companies, a trend that has been building steadily across the industry for several years.
Conclusion
Marketing and advertising India GCC story looks different from healthcare or BFSI, shaped by an industry that has consolidated into fewer, larger global players rather than expanded into many independent ones. But the underlying pattern is familiar: work that once sat firmly at global headquarters, research infrastructure, data science, creative R&D, media strategy, increasingly runs out of India instead.
That shift is still accelerating, not slowing down.
