Nikhil Kamath x Nandan Nilekani | People by WTF | Ep #3

India today is a different India, when compared to 10 years ago. A lot of it has to do with The India Stack Journey (a set of open API's & digital public goods). Interesting to note how opportunity to serve at population scale is the theme of these innovations. In this episode of People by WTF, we sat with Nandan Nilekani to understand the trajectory of building this advanced Digital Public Infrastructure in India, which has made a significant impact in each of our day to day lives.

WHAT IT’S REALLY ABOUT

Nandan Nilekani explains India Stack, UPI, and startup opportunities today

  1. Nikhil Kamath interviews Nandan Nilekani on the origins and evolution of India Stack—starting with Aadhaar as a digital-first unique ID and expanding into eKYC, eSign, DigiLocker, and UPI as open API “public rails” for private innovation.
  2. Nilekani frames the core design principle as “population scale”: digital systems must work for everyone to truly shift inclusion, formalization, and economic growth in India.
  3. They map key inflection points (especially 2016: 1B Aadhaar, UPI launch, Jio’s data revolution, demonetization, BHIM) and discuss newer layers like Account Aggregator (consent-based data exchange), Fastag as a vehicle identity/payment rail, and protocol approaches like Beckn/ONDC.
  4. The conversation closes with views on AI (LLMs as commodities; value in Indian-language voice interfaces), and “Finternet” (tokenization + mainstream finance) as a possible next architecture shift—while emphasizing that the best startup ideas often come from unexpected, practical frictions.

IDEAS WORTH REMEMBERING

5 ideas

India Stack is designed as public rails with private innovation on top.

Nilekani repeatedly stresses the internet/GPS analogy: government-funded, open, API-led infrastructure enables startups and incumbents to build competitive services without rebuilding core primitives.

Aadhaar’s differentiator was making ID online-verifiable in real time.

The mandate began as “unique ID,” but Nilekani pushed a digital-first approach: online authentication so a person can prove identity instantly, enabling downstream services like bank accounts and SIM issuance.

Regulatory buy-in is as important as technology for infrastructure adoption.

Aadhaar-based KYC required multi-year coordination across RBI, TRAI/DoT, IRDA, SEBI and legal frameworks (e.g., PMLA). The “rails” only became transformative once regulators accepted them broadly.

2016 combined multiple tailwinds that accelerated digital adoption at once.

Nilekani lists 1B Aadhaar (April), UPI launch (April), Jio (September), demonetization (November), and BHIM (December) as a compounding set of shocks that shifted India from “voice economy” to “data + digital payments.”

UPI scaled because it made money movement as simple as messaging.

Unlike net-banking-era transfers, UPI made peer-to-peer payments real-time, app-based, and interoperable across banks/apps via a shared protocol—then got boosts from demonetization and the pandemic’s QR behavior.

WORDS WORTH SAVING

If you're going to build an ID, it has to be a digital ID. It has to be online. It has to be verifiable online with real time.
