Staying Relevant When Technology Never Stops Changing

Staying Relevant When Technology Never Stops Changing

July 3, 2026

Lessons from INT.’s 28-year journey of reinvention, enterprise AI, and long-term value creation Technology has a strange way of making yesterday’s advantage feel ordinary. Every few years, the industry finds a new center of gravity. Infrastructure gave way to the cloud. Cloud accelerated digital transformation. Digital transformation made data central to business decisions. And now, artificial intelligence is reshaping how enterprises think, operate, compete, and grow. For business leaders, this pace of change creates pressure. For technology companies, it creates an even deeper challenge: how do you stay relevant when the market itself keeps changing? This question was at the heart of a recent conversation between Maria Perez and Abhishek Rungta, Founder & CEO of Indus Net Technologies (INT.), for The Guardian’s India Special Report. The discussion explored INT.’s nearly three-decade journey, its evolution through multiple technology waves, its approach to enterprise AI, and the growing opportunity for India-UK technology collaboration. But beyond the interview, one larger idea stood out clearly: Sustainable technology companies are not built by chasing every trend. They are built by learning how to evolve before the market forces them to. Executive Summary INT.’s journey offers a practical view of what it takes to remain relevant in an industry defined by constant change. Since 1997, the company has evolved from digital infrastructure to digital engineering, digital transformation, and now enterprise AI transformation. The key themes from this perspective are: For INT., staying relevant has never been about adding new labels to services. It has been about staying close to client problems, investing in people, and building capabilities that continue to create value as business needs change. Relevance Is Harder to Build Than Growth Growth is often visible. Relevance is harder to measure. A company can grow because the market is expanding, demand is strong, or a particular technology cycle is favorable. But staying relevant for nearly three decades requires something more disciplined. This has shaped INT.’s evolution since 1997. The company began in digital infrastructure, expanded into digital engineering, moved into nterprise AI transformation, and is now helping enterprises navigate AI-led transformation. This journey reflects more than a change in service categories. It reflects a deliberate pattern of reinvention. For INT., reinvention does not mean abandoning the past. It means keeping the principles stable while allowing capabilities to evolve. The principle is simple: solve real client problems. The capabilities around that principle must keep changing. Enterprises Need Signal, Not Noise Every major technology wave creates noise. Cloud created noise. Digital transformation created noise. Data platforms created noise. Generative AI and agentic AI are creating noise now. Noise can create awareness and urgency, but it becomes dangerous when it replaces strategy. Many enterprises today are under pressure to “do something with AI.” Boards are asking questions. Competitors are launching pilots. Employees are experimenting with public tools. Vendors are making aggressive claims. In this environment, the most valuable role a technology partner can play is not to add more excitement. It is to create clarity. Enterprise leaders need to know: This is where INT.’s philosophy of separating signal from noise becomes important. Technology should not be adopted because it is fashionable. It should be adopted because it improves how a business works. That is especially true for AI. The issue is not whether enterprises should adopt AI. They should. The real question is whether they are prepared to adopt AI in a way that is secure, useful, scalable, and connected to business value. That is where thoughtfulness matters more than speed. Customer-Centricity Is Tested in Long-Term Decisions Customer-centricity is one of the most overused phrases in business. Almost every technology company claims it. Very few define what it means when difficult decisions need to be made. In enterprise technology, the wrong recommendation can be expensive. A cloud decision can shape infrastructure costs for years. An AI model choice can influence flexibility, governance, and operating cost. A software architecture decision can affect scalability and maintainability. A third-party tool can become either an accelerator or a constraint. For INT., customer-centricity means technology recommendations should be based on what is right for the client, not on commissions, preferred alliances, or short-term commercial convenience. This is not just an ethical stance. It is a strategic one. Enterprises need partners who can think beyond the first implementation. They need partners who understand lifetime total cost of ownership, long-term maintainability, and future flexibility. The cheapest solution is not always the most cost-effective. The best solution is the one that continues to create value across its lifecycle. This long-term view has shaped INT.’s client relationships. The company’s average client relationship extends beyond seven years, while its average employee tenure is over six years. These numbers reflect something that cannot be manufactured through marketing. They reflect trust. And in enterprise transformation, trust is not a soft metric. It is a business advantage. Enterprise AI Cannot Be Another Isolated Tool The current AI conversation is often too tool-centric. New models are launched. New interfaces are introduced. New use cases are promoted. New promises are made. But enterprises do not operate in clean environments. They operate across ERP systems, CRMs, HR platforms, data repositories, cloud infrastructure, shared drives, emails, documents, chats, spreadsheets, legacy applications, and industry-specific systems. Their data is structured and unstructured. Their workflows are distributed. Their permissions are complex. Their compliance obligations are serious. This is why enterprise AI cannot be treated like individual AI usage. A public AI tool can help an individual write, summarize, or research faster. But enterprise AI must do something far more complex. It must work within the organization’s own context. Enterprise AI must: This is the challenge INT. is addressing with INT. OneSpace. OneSpace is designed as a secure enterprise AI layer that connects structured and unstructured organizational data, enabling companies to create company-specific GPTs, intelligent agents, and AI-led workflows within proper governance boundaries. The idea is not to force enterprises to replace every system they already use. That would be unrealistic for many organizations. The more practical opportunity
