Best Buy's decision to transition its India Global Capability Centre (GCC) to Tata Consultancy Services rather than maintaining it as a captive unit reflects a strategic calculation balancing control, cost, and capability. The electronics retailer faced mounting pressure to accelerate its AI transformation while managing operational complexity. By partnering with TCS, Best Buy gains access to a dedicated AI-native operating model without bearing the full burden of infrastructure investment and talent acquisition at scale.
The deal structure is telling.
This arrangement allows Best Buy to maintain strategic oversight while leveraging TCS's execution capabilities. The transition involves approximately 450-600 employees who will join TCS's global organization, retaining their existing business and technology knowledge while gaining access to TCS's learning programs, AI skills, and global opportunities.
Best Buy had evaluated proposals from multiple vendors including Accenture and Wipro. TCS emerged victorious based on pricing, service-level agreements, and demonstrated productivity benefits. The existing relationship between TCS and Best Buy, already generating an estimated $75-100 million in annual revenue, provided a foundation of trust that proved decisive. For Best Buy, this isn't about cost arbitrage—it's about building an AI-first retail engine faster than it could alone.
The five-year deal structure enables a phased approach to AI-native transformation, avoiding the disruption of abrupt change. Under the agreement, Best Buy's India entity will continue supporting the US retailer's business while gradually evolving into an AI-native capability center. TCS will use its Global Value & Innovation Centres (GVIC) framework to develop the center into an AI-led engine focused on innovation and enterprise value.
The transformation follows a clear progression. In the initial phase, employees transition to TCS while maintaining operational continuity. The middle phase focuses on redesigning workflows and developing AI-powered solutions. The final phase scales capabilities across Best Buy's business, with the Bengaluru center evolving into the company's "heart of innovation" for mobile and AI platforms—a role Best Buy had envisioned when establishing the 70,000-square-foot technology center in 2024.
This gradual approach mitigates risk while building momentum. Rather than attempting a wholesale overhaul, TCS can demonstrate value through targeted wins—automating specific workflows, improving customer experience touchpoints, optimizing supply chain operations—and then expand successful patterns across the organization. The multi-year commitment provides the runway needed for genuine transformation rather than superficial technology adoption.
For TCS, this acquisition delivers multiple strategic benefits beyond the immediate revenue.
The Best Buy deal introduces higher-value AI services into the mix, shifting the revenue composition toward offerings that management notes have "definitely much better than TCS average" productivity compared to traditional business. Transcript
The deal also strengthens TCS's competitive positioning in the rapidly evolving GCC market. The global GCC IT services market is projected to grow from $192.50 billion in 2025 to $355.00 billion by 2030 at a 13.02% CAGR, driven by enterprise demand for AI-native transformation. India hosts over 1,800 GCCs employing 1.9 million professionals, and companies are increasingly seeking technology services providers to build and transform these centers rather than maintaining them as standalone units.
By absorbing Best Buy India's existing business and technology knowledge, TCS gains deep retail domain expertise that can be leveraged across its Consumer Business Group client base. The 450-600 transitioning employees bring understanding of consumer electronics retail, omnichannel operations, customer experience insights, and supply chain intelligence. This domain knowledge, combined with TCS's AI capabilities, creates differentiated value that neither party could achieve independently.
TCS brings formidable AI capabilities to this partnership. The company reported $2.6 billion in annualized AI revenue in Q1 FY27, with 312,000+ associates possessing higher proficiency in AI/ML. TCS has developed a comprehensive Human + AI Service Autonomy Model with a five-level framework progressing from using AI as a tool to building an agentic enterprise. The company's proven retail implementations include deploying 70 AI agents for IT operations that achieved 30% faster remediation and 80% fewer incidents, and store operations transformations that boosted sales by 25% while saving store managers 90 minutes weekly.

The dedicated GVIC business unit, launched in June 2026 and headed by Soumen Roy, plays a crucial role in scaling the Best Buy transformation. This unit provides an end-to-end model covering strategy, setup, scaling, and AI-led transformation. The GVIC framework combines a Human + AI operating framework with AI-ready data and cloud foundations, enterprise platforms, responsible AI frameworks, and future-ready talent models. Soumen Roy, formerly Country Head of TCS Canada with nearly three decades of experience across industries and geographies, brings deep understanding of North American market dynamics and proven ability to build and scale operations.
The combination creates unique value. Best Buy's domain expertise provides the context that makes AI solutions effective—retail-specific AI models trained on Best Buy's business processes, customer journey understanding enabling personalized AI interactions, product knowledge ensuring accurate AI-powered recommendations. TCS's AI capabilities provide the technology foundation—agentic AI platforms for autonomous decision-making, memory-rich AI maintaining context across customer interactions, predictive analytics for demand forecasting and inventory optimization.
The transition of 450-600 Best Buy India employees to TCS presents both challenges and opportunities. TCS has established itself as an industry leader in employee retention with the highest retention rate in the IT services industry, supported by comprehensive retention strategies. The company addresses transition challenges through a three-pillar employee value proposition applied globally: Work (multiple sectors, diverse technologies), Growth (career-linked learning, clear progression paths), and Whole Person (support across work, family, leisure, and community engagement).
TCS's AI skilling infrastructure is enterprise-scale. The #iamGenAIReady program trains employees on AI/GenAI for customer project deployment. The AI Experience Zone provides a multi-platform playground for developing higher GenAI competencies through industry-specific use cases. Fresco Playgrounds offer approximately 260 playgrounds for hands-on learning, including 20 new ones dedicated to GenAI and Cybersecurity. The world's largest AI hackathon featured 281,000 participants and 500,000+ solution submissions. Annual Report +1
Balancing domain knowledge retention with AI upskilling requires a deliberate approach. TCS's OneTD learning framework includes dedicated focus on Domain skills alongside Technology, Leadership, Functional, and Process pillars, ensuring a #LifeLongLearning culture that values domain expertise. The company is systematically reviewing all components of its role framework with AI as the centerpiece, creating new roles like rapid-build engineers while evolving existing domain expert roles.

The Best Buy deal reflects broader GCC market trends where companies increasingly partner with technology services providers for AI-native transformation. The market is witnessing a structural shift from pure captive centers to hybrid partnerships. One in two companies now report that outsourcing failures have at least doubled in financial impact over the past five years, with incidents routinely costing between $0.5 billion and $1 billion each. Meanwhile, 56% of GCCs drive enterprise-wide transformation via GenAI, data & cloud, and 86% support the enterprise's tech innovation agenda.
TCS faces significant competition from Accenture, HCLTech, Infosys, and others. Accenture was a direct competitor in the Best Buy deal and brings strong consulting heritage and comprehensive AI platforms. HCLTech is recognized as a Leader in Everest Group's 2025 PEAK Matrix for GCC Setup and Transformation, with Enterprise AI Foundry and AI Force frameworks. However, TCS's first-mover advantage with its dedicated GVIC business unit, proven AI capabilities at scale with $2.6B annualized AI revenue, and largest AI-skilled workforce provide distinct competitive advantages.
The appointment of Soumen Roy as Head of TCS GVIC Business Unit strengthens this positioning. His experience as Country Head of TCS Canada provides deep understanding of North American market dynamics, while his track record leading TCS Japan growth demonstrates ability to succeed in diverse markets. The GVIC framework's focus on AI-native from inception, rather than AI as an add-on service, differentiates TCS from competitors who may treat AI transformation as a project rather than an operating model.
As the GCC market evolves toward AI-native operations, TCS is positioning itself to capture significant share of the projected $355 billion market by 2030. The Best Buy deal serves as both a referenceable success story and a blueprint for how captive centers can transform into AI-led innovation engines. For companies navigating the complex transition from traditional operations to AI-native capabilities, TCS offers a proven path that balances strategic control with operational excellence.
