India’s GCCs are building global AdTech stacks. Will India ever own it?

For years, India’s Global Capability Centres occupied a peculiar place in the global advertising ecosystem.

They were important, certainly. Useful, definitely. But glamorous? Hardly. If New York, London, and San Francisco were where the advertising industry imagined strategy, product vision, and innovation happened, India was where the dashboards got cleaned, the reports got filed, the QA got done, and somebody quietly fixed the campaign that broke at 2 am.

That arrangement is beginning to crack.

As of FY26/March 2026, India has 2,117 GCCs across 3,728 units, employing 2.36 million people and generating $98.4 billion in revenue, according to the Zinnov-Nasscom GCC Landscape 2026 report. The number of GCCs has grown 32% since FY21, and 506 Forbes Global 2000 companies now run operations from India.

The scale itself is enormous. But the more interesting story is not how many GCCs India has. It is what many of them are now building.

Increasingly, Indian GCC teams are working on the technical core of modern AdTech: bidding infrastructure, identity-resolution systems, clean-room integrations, retail-media plumbing, measurement frameworks, audience-intelligence layers, and AI-led optimisation engines. In other words, the machinery powering programmatic advertising is increasingly being engineered out of India.

Gopa Menon, COO and co-founder, TheBlurr, says the change is no longer superficial. “For a long time, GCCs in India were essentially execution arms running campaign ops, managing dashboards, doing the QA work that nobody in the US or UK headquarters wanted to touch. That story has genuinely changed,” he says.

“What’s happening now is that teams in Bangalore, Hyderabad, and Gurgaon are owning the product roadmap for things like identity resolution pipelines, clean room integrations, and programmatic bidding logic. This isn't staff augmentation anymore.”

The timing is not accidental. Advertising itself has become a far more engineering-heavy business over the past five years. The collapse of third-party cookies forced platforms to rethink identity and targeting infrastructure. Retail media networks turned commerce platforms into media owners, and India is seeing that transformation happen in real time, in double time. AI systems began reshaping optimisation and campaign automation. Streaming fragmented measurement across screens, devices, and login environments.

The result is that modern advertising infrastructure increasingly resembles a large-scale software problem.

And India happens to possess exactly the kind of engineering ecosystem those problems require.

Build in India?

Shradha Agarwal, Co-founder and Global CEO, Grapes Worldwide, sees this shift in the way GCC conversations themselves have changed. According to her, the discussion is no longer restricted to execution and delivery. Indian teams are increasingly getting involved in how products are built and improved, particularly across retail media, identity, data systems, and measurement.

That agency-side view is important because agencies often sit closest to the gap between platform promise and campaign reality. The more complex the advertising stack becomes, the less useful it is to treat India merely as an implementation layer. A market managing audience fragmentation, quick-commerce growth, walled gardens, DPDP compliance, and streaming measurement is also a market capable of asking sharper infrastructure questions.

India’s technology industry is expected to cross $315 billion in FY26, according to Nasscom estimates, while AI-related services revenue is estimated at $10-12 billion. At the same time, India’s digital advertising market continues expanding rapidly. PMAR 2026 pegged the country’s advertising market at Rs 1.55 lakh crore in 2025 under its expanded AdEx definition, while the dentsu-e4m Digital Advertising Report 2026 estimated digital advertising alone at Rs 71,621 crore.

That combination matters. India is no longer simply a massive engineering base. It is also becoming one of the world’s largest and fastest-growing digital advertising markets. The country now sits at the intersection of talent, data, scale, AI infrastructure, retail-media growth, and a domestic advertising economy large enough to matter in its own right.

Tejas Maha, Associate Director - Media, White Rivers Media, points to the same shift from an operations lens. He notes that Indian GCC teams are contributing to deeper AdTech layers including optimisation engines, fraud detection systems, retail-media infrastructure, identity resolution, and audience frameworks. In his view, the work has moved closer to the technical core of AdTech, particularly in larger and more mature GCC setups.

That movement from campaign operations to platform engineering is the critical pivot. It is one thing to run media plans on someone else’s rails. It is another to help build the rails themselves.

GCCs of Gravity

Menon points to a broader structural shift underway inside the global advertising ecosystem. “When a Trade Desk or a Nielsen or a PubMatic has 400-600 engineers sitting in India who are building the actual DSP infrastructure or the measurement layer, the centre of gravity for where the thinking happens shifts.”

That “centre of gravity” argument is perhaps the most important part of the GCC conversation.

Because this is no longer merely about cost arbitrage and India’s GCC ecosystem is increasingly moving toward capability arbitrage.

Sanjil Zaveri, General Manager, Brandtech+, places the shift within the broader transformation of marketing technology. He says Indian teams are increasingly embedded inside product-development cycles, participating in experimentation engines, AI-led decisioning models, scalable automation systems, and creative-production workflows that support global marketing transformation.

This is where the GCC story begins to look less like a labour-market story and more like a power story. If Indian teams are shaping the infrastructure, models, and automation layers that global advertisers use, then India’s role in AdTech is no longer peripheral. It is increasingly foundational.

Meher Patel, Founder, Hector, adds another layer to this evolution. He points to India’s growing role in platform scalability, architecture decisions, and AI-native AdTech engineering as global advertising systems become more data-intensive and machine-learning driven. In other words, India is not only writing code against a roadmap created elsewhere. In several cases, it is helping determine how systems are architected, scaled, and automated.

But beneath the optimism lies a more uncomfortable question: If India is increasingly building the stack, why does ownership of the stack still largely sit elsewhere?

Answers, and more questions

Rajiv Dingra, Founder and CEO, ReBid, frames the distinction most sharply.

“There is a difference between building the stack and owning the stack,” he says, noting, “Today, a lot of deep engineering and innovation may happen in India, but strategic ownership, product roadmaps and commercial IP often still sit with global HQs.”

That distinction may ultimately define the next phase of India’s AdTech evolution. Building infrastructure is not the same thing as controlling the economics around it. Commercial relationships, advertiser trust, monetisation frameworks, governance decisions, and product direction still remain largely concentrated within global headquarters.

That matters because AdTech is not merely a technology business. It is a market-access business, a data business, a trust business, and increasingly, a regulatory-navigation business.

India may be building large parts of the machine, but the buttons are often still elsewhere.

Menon argues that this has significant implications for Indian agencies. “If global AdTech platforms are engineering their stacks out of India, they're also building deeper proprietary moats,” he says, adding, “Agencies need to be building genuine data and technology capabilities of their own, not just reselling platform access.”

That warning should land uncomfortably in an agency market that has often been content to dress up platform dependency as digital sophistication. If the world’s largest AdTech platforms are using Indian engineering depth to make their systems more powerful, more automated, and more closed, Indian agencies cannot afford to remain glorified access brokers.

The publisher question is equally uneven.

Better-engineered monetisation and measurement infrastructure may eventually improve Indian inventory economics. But much of that infrastructure is still designed around Western advertiser priorities, Western audience graphs, and Western market structures. Indian publishers, especially vernacular and mid-tier ones, may get better tools without necessarily getting a say in how those tools are designed.

For homegrown AdTech startups, meanwhile, the GCC boom cuts both ways.

On one hand, India now has thousands of engineers working on programmatic infrastructure, identity systems, clean rooms, retail media technology, and AI-led optimisation at global scale. A decade ago, that depth of applied AdTech expertise barely existed locally. Some of that talent will inevitably spill outward into startups, independent platforms, and specialist product companies.

On the other hand, competing against globally entrenched AdTech ecosystems becomes harder when those same global platforms are already deeply embedded inside advertiser relationships and supported by world-class engineering teams sitting in India.

“The real question is whether India will only remain the builder of global AdTech stacks, or also become the owner and exporter of new AdTech platforms,” Dingra says, concluding, “The next phase will not be about whether Indian teams can build world-class AdTech infrastructure. They already can. India has both the talent and market complexity to lead that evolution — provided the mandate moves from execution to ownership.”
