HCLTech partners with Thought Machine to help banks replace legacy systems with AI and cloud-native core platforms

HCLTech partners with Thought Machine to accelerate AI-led core banking transformation. Find out how this global deal may reshape digital banking in 2025.

HCLTech (NSE: HCLTECH) has entered into a global strategic partnership with cloud-native banking platform provider Thought Machine to accelerate the digital transformation of banks and financial institutions seeking to move away from legacy infrastructure. The collaboration brings together Thought Machine’s next-generation Vault Core platform and HCLTech’s full-stack transformation expertise to help both incumbent banks and new-age challengers transition into intelligent, autonomous financial ecosystems.

The announcement, made jointly by the two firms on Tuesday, positions HCLTech as a certified global transformation partner for implementing Thought Machine’s flagship platforms — Vault Core and Vault Payments. The strategic aim is to help banks modernize operations, reduce technical debt, and deploy real-time, scalable financial products with greater agility, all underpinned by AI, cloud, and data-centric architectures.

How does the partnership between HCLTech and Thought Machine support AI-first digital banking?

Thought Machine’s Vault Core is widely regarded as one of the most advanced cloud-native banking platforms on the market, designed to give banks complete control over product design and deployment. Unlike traditional core systems that are monolithic and inflexible, Vault’s architecture is modular, fully API-enabled, and supports real-time processing, which aligns with the growing institutional push for AI-led automation, embedded finance, and composable banking.

Under the new agreement, HCLTech will provide Vault-certified delivery services supported by global Centers of Excellence (CoEs) and deep regulatory compliance expertise. The Indian technology company will also establish a dedicated CoE for Vault Core and Vault Payments, serving as a launchpad for custom deployments, DevSecOps frameworks, and digital onboarding experiences. The goal is to shorten time-to-market for financial product rollouts while maintaining high security and compliance standards.

HCLTech’s Executive Vice President and Head of Financial Services for Europe and UKI, Sudip Lahiri, said that the partnership reflects the company’s vision to shape the future of “autonomous banking” through AI and cloud transformation. Lahiri stated that the joint offering with Thought Machine would help financial institutions eliminate operational silos, improve resiliency, and accelerate innovation cycles.

What is Thought Machine’s role in reshaping cloud-native core banking infrastructure?

Founded in the UK, Thought Machine has emerged as one of the leading providers of next-gen core banking infrastructure. Its cloud-native Vault Core platform and Vault Payments solution are used by major financial institutions worldwide — including Lloyds Banking Group, SEB, Standard Chartered, ING Bank Śląski, and Intesa Sanpaolo. Unlike legacy software vendors who retrofit cloud capabilities onto aging systems, Thought Machine built its architecture from scratch using native cloud design principles.

Vault Payments, the firm’s newer offering, is a real-time payments platform featuring a Universal Payment Engine that supports a wide range of payment types — including card-based transactions, account-to-account transfers, and emerging fintech rails. This gives banks flexibility to innovate across both retail and commercial segments without having to overhaul their entire tech stack.

Randy McFarlane, Global Head of Partnerships at Thought Machine, called the collaboration with HCLTech a “significant step” toward enabling financial institutions to adopt “truly digital-first models.” He emphasized that the combined strengths of the two companies would deliver “self-optimizing systems that evolve with customer needs.”

How are institutional clients expected to benefit from this global offering?

Industry analysts noted that the HCLTech–Thought Machine alliance arrives at a time when many Tier 1 and Tier 2 banks are actively seeking to de-risk their legacy systems while pursuing modular modernization strategies. The move toward composable core banking, where banks stitch together best-of-breed solutions across layers, has intensified in recent quarters — particularly in Europe, Southeast Asia, and Latin America.

From an enterprise buyer’s perspective, the ability to access Vault-certified services through HCLTech’s delivery pipeline offers scalability and compliance assurance. Moreover, the integration of Vault Core with AI-led orchestration frameworks, cloud-native microservices, and DevSecOps pipelines aligns with ongoing global trends in open banking, embedded finance, and real-time payment modernization.

The offering is expected to resonate with neobanks, digital-only spinoffs, and greenfield initiatives by incumbent institutions, especially those struggling with regulatory fragmentation and high technical debt.

What does the partnership mean for HCLTech’s positioning in global financial services IT?

This deal marks a significant step in HCLTech’s ongoing pivot toward high-value digital transformation services. While the Indian IT major has deep roots in financial services technology, the new partnership reinforces its shift from traditional outsourcing models to cloud-native modernization, AI enablement, and platform-based delivery.

With Vault deployments already gaining traction across EMEA, APAC, and North America, HCLTech’s role as a global implementation partner offers a potential pipeline of multi-year transformation contracts. Analysts expect the deal to boost HCLTech’s presence among Tier 1 banks, given the company’s regulatory know-how and deep domain expertise.

Moreover, HCLTech’s ability to integrate Vault Core with broader enterprise platforms — including data lakes, CRM, fraud detection engines, and credit decisioning systems — positions it as a transformation partner for end-to-end banking modernization.

How are financial markets and institutional investors reacting to the development?

As of August 26, 2025, HCLTech (NSE: HCLTECH) stock has been trading relatively flat, with marginal intraday movement following the announcement. While there was no immediate surge in buying activity, institutional investors appear to view the deal as a long-term play to capture market share in the high-growth banking-as-a-service (BaaS) and core transformation segments.

Investor commentary on public forums and trading platforms has emphasized the strategic value of the Vault platform as part of a broader cloud modernization portfolio. However, some analysts caution that ramp-up in revenue contribution from such platform-led deals typically occurs over multiple quarters, with upfront investments in CoEs and certification programs potentially weighing on short-term margins.

There is also growing interest from foreign institutional investors (FIIs) in Indian IT stocks with exposure to core banking modernization themes, especially in markets with stringent regulatory requirements and modernization incentives.

What lies ahead for HCLTech and Thought Machine in the next phase of banking innovation?

Looking ahead, both companies are expected to deepen their joint go-to-market strategy by targeting specific geographies with high modernization potential — including Southeast Asia, MENA, and select parts of Europe where digital banking mandates are being accelerated by regulators.

Future phases of the partnership may include co-development of AI-native modules for hyper-personalization, fraud analytics, and ESG-compliant financial products. With Thought Machine’s roadmap already pointing toward composability and autonomy, HCLTech’s role as an integrator, optimizer, and orchestrator will become more critical in helping clients realize end-to-end modernization.

If executed successfully, this collaboration could help redefine the playbook for how banks evolve into intelligent financial ecosystems — not just with cloud adoption, but through true platform transformation that embeds AI, data, and compliance at every layer.
