Nandan Nilekani on Scale Economics

Speaking at Stanford on 27 May 2025, Nilekani framed Aadhaar and UPI as twin pillars of India's digital public infrastructure for 1.4 billion people. Stanford's Dean Arun Majumdar called him one of a handful of people who laid the foundation of modern India — an unusually strong endorsement from an academic institution normally cautious in its language.

Nilekani argued that lack of basic identity — birth certificate, licence, any proof — had historically oppressed ordinary Indians: they could not board buses or trains, could not satisfy a policeman, could not open a bank account. DPI was framed as a structural fix to that everyday exclusion, not as a tech showcase.

He told Stanford that economic inequity of this scale cannot be solved by traditional spending: India has to do a lot more with a lot less money, and do it faster. DPI is, in his framing, the only practical lever to deliver large-impact inclusion without bankrupting the state.

Nilekani served as Infosys CEO from March 2002 to April 2007, during which the firm's revenue grew roughly sixfold to about three billion dollars. He then handed the CEO role to colleague Kris Gopalakrishnan and moved to co-chairman of the board — an early example of the planned, founder-led succession pattern Infosys institutionalised.

By mid-2025, 1.4 billion Indian residents had Aadhaar, 750 million had opened bank accounts using it, and electronic money transfers had moved without fraud at population scale — figures Nilekani presents as proof that the inclusion thesis works in practice, not just in policy papers.

Nilekani also played a key role in creating the Unified Payments Interface, the real-time digital-payments rail that has reshaped Indian retail transactions. He chaired the committee that framed the digital-payments architecture after demonetisation, and has repeatedly invoked UPI as a template for what he calls the next great Indian infrastructure wave — likely in energy.

Rural farmers can now use Aadhaar and the broader DPI stack to access loans, then accept payment via UPI — an end-to-end economic flow built on top of identity plus payments plus credential storage, what Nilekani describes as paths for growth that did not exist before DPI.

Backing the identity and payments layers is an MEITY initiative that securely stores credentials — driver's licences, vaccination records, academic certificates — in the cloud. More than half a billion people use it, holding around nine billion documents, an astonishing density of verified personal data at population scale.

Beyond Infosys and UIDAI, Nilekani co-founded and chairs EkStep Foundation, a non-profit building a learner-centric technology platform aimed at improving basic literacy and numeracy for millions of Indian children — an extension of the same DPI thinking into early-stage education at population scale.
