Not long ago, opening an investment account in India often meant filling out forms, submitting physical documents, and waiting days for verification. Today, the same process can be completed from a smartphone in a matter of minutes. Sending money across the country takes seconds. Buying a mutual fund or applying for an IPO no longer requires a visit to a bank or brokerage office.
These changes have become so routine that they are easy to overlook. Yet together, they represent one of the most significant shifts in India’s economic landscape over the past decade.
India fintech revolution did not emerge from a single company or a breakthrough product. It was built on a combination of public digital infrastructure, expanding internet access, supportive regulation, and a growing willingness among millions of Indians to embrace digital financial services. The result is an ecosystem that has transformed how citizens save, borrow, invest, and make payments while creating new opportunities for entrepreneurs and financial institutions alike.
At the heart of this transformation lies India’s Digital Public Infrastructure (DPI). Platforms such as Aadhaar, the Unified Payments Interface (UPI), DigiLocker, and paperless e-KYC have reduced many of the barriers that once slowed access to financial services. These systems have enabled private innovation without requiring every company to build the basic digital rails from scratch.
The impact now extends well beyond India’s borders. According to the Ministry of Electronics and Information Technology (MeitY), India has signed agreements with 23 countries to cooperate on Digital Public Infrastructure, while UPI is operational in more than eight countries, including the UAE, Singapore, Bhutan, Nepal, Sri Lanka, France, Mauritius and Qatar. The government sees these partnerships as part of a broader effort to share India’s digital governance model and strengthen international cooperation in digital payments.
The rapid expansion of this ecosystem has created fertile ground for a new generation of fintech companies. Some have focused on digital lending, others on insurance or payments. Nextbillion Technology, the original operating entity behind Groww before its corporate renaming, is one such example. Its growth reflects how startups have been able to leverage India’s digital infrastructure to simplify investing for millions of users. The company’s story, however, is only one chapter in a much larger national transformation.
This article examines how India’s fintech ecosystem evolved, the role of Digital Public Infrastructure in accelerating financial inclusion, and why the next phase of growth is likely to depend not only on technological innovation but also on trust, regulation, and sustainable business models.
The Digital Foundations of India’s Fintech Revolution
Every major technological shift begins with infrastructure. For India’s fintech sector, that infrastructure was not built by private companies alone. It emerged through a combination of public policy, digital innovation, and institutional reform that gradually changed how citizens interacted with financial services.
The first milestone was financial inclusion. The launch of the Pradhan Mantri Jan Dhan Yojana (PMJDY) brought millions of previously unbanked citizens into the formal banking system. Aadhaar provided a trusted digital identity, while mobile connectivity ensured these services reached beyond major cities. Together, they created the foundations of what would later become known as the JAM trinity—Jan Dhan, Aadhaar and Mobile.
The next breakthrough came with the Unified Payments Interface (UPI). Instead of relying on card networks or lengthy bank transfers, users could send and receive money instantly using a mobile phone. Small merchants, street vendors, professionals and businesses quickly adopted the platform, making digital payments a part of everyday life. The scale of adoption has attracted international attention, with UPI now operational in multiple countries and serving as a model for cross-border digital payment partnerships.
India’s digital ecosystem continued to expand through platforms such as DigiLocker, API Setu, CoWIN, UMANG, and the Government e-Marketplace (GeM). While these initiatives serve different purposes, together they demonstrate a broader approach: building shared digital infrastructure that private innovators can build upon rather than duplicate.
The government has also begun taking this model overseas. According to the Ministry of Electronics and Information Technology, India has signed cooperation agreements with 23 countries to share elements of its Digital Public Infrastructure. These partnerships cover areas such as digital identity, payment systems, document verification and digital governance, reflecting India’s growing role in shaping global conversations around public digital infrastructure.
For fintech startups, these developments dramatically reduced the cost of serving customers. Opening an investment account, completing identity verification or transferring funds became significantly faster than in the past. Companies could devote more resources to improving products and customer experience instead of recreating foundational digital systems.
This environment created the conditions for firms such as Nextbillion Technology to expand rapidly. Rather than succeeding in isolation, such companies benefited from an ecosystem where public digital infrastructure and private innovation increasingly complemented one another. India’s fintech revolution, therefore, is not simply the story of successful startups—it is also the story of how digital public infrastructure altered the economics of financial services.
From Digital Payments to Digital Investing
The success of India’s fintech sector is often measured through UPI transaction volumes or the rapid expansion of digital payments. Yet another transformation has quietly unfolded alongside it—the rise of digital investing.
For decades, investing in equities and mutual funds remained largely confined to urban centres and financially aware households. Opening a demat account involved paperwork, physical verification and multiple interactions with intermediaries. While the market offered opportunities, access was neither simple nor widespread.
That began to change as digital infrastructure matured. Aadhaar-based authentication, electronic Know Your Customer (e-KYC) verification and online payment systems removed many of the procedural hurdles that had discouraged first-time investors. Combined with affordable smartphones and lower internet costs, these changes made financial markets more accessible than ever before.
The COVID-19 pandemic further accelerated this shift. Lockdowns encouraged greater reliance on digital services, while increased public interest in personal finance and wealth creation brought a new generation of retail investors into the market. Investment platforms witnessed a surge in account openings as many Indians began exploring mutual funds, equities and exchange-traded funds for the first time.
Among the companies that benefited from this changing landscape was Nextbillion Technology, the original operating entity behind the Groww platform. Founded in 2016 by four former Flipkart executives, the company initially focused on simplifying mutual fund investments before expanding into stockbroking and a wider range of financial products. Its growth reflected a broader trend rather than an isolated success story—technology was lowering the barriers to investing, and millions of Indians were willing to embrace it.
The emergence of platforms like Groww, Zerodha, Upstox and others has fundamentally altered how retail investors participate in India’s capital markets. Competition has encouraged simpler user experiences, lower costs and greater transparency, while educational content and mobile-first design have made investing less intimidating for newcomers.
This shift has implications beyond the fintech industry. Greater retail participation can deepen domestic capital markets, diversify household savings and reduce dependence on traditional investment avenues. At the same time, it places greater responsibility on platforms and regulators to promote informed investing, protect consumers and maintain confidence in digital financial services.
India’s fintech revolution, therefore, is not only changing how people make payments. It is gradually reshaping how they think about savings, investments and long-term wealth creation.
