Reference excerpt

Nandan Mohanrao Nilekani is an Indian entrepreneur. He co-founded Infosys and is the non-executive chairman of Infosys replacing R Seshasayee and Ravi Venkatesan, who were the co-chairs of the board, on 24 August 2017. After the exit of Vishal Sikka, Nilekani was appointed non-executive chairman of the board effective 24 August 2017. He was the chairman of the Unique Identification Authority of India (UIDAI). After a successful career at Infosys, he headed the Government of India's technology committee, TAGUP. He is a member of Indian National Congress but not active in politics as of 2019. As of October 2025, he is the 100th richest person in India with a net worth of US$3.2 billion. In July 2026, Government of India announced the constitution of a high-powered task force, to be headed by Nilekani, to recommend steps to make the country’s examination system leak-proof and technology-driven.

Early life and education Nilekani was born in Bangalore, Karnataka. His parents, Durga and Mohan Rao Nilekani, were Konkani-speaking people originally from Sirsi. His father worked as the GM of the Mysore and Minerva Mills and subscribed to Fabian Socialist ideals, which influenced Nilekani during his early years. His elder brother, Vijay, works at the Nuclear Energy Institute in the U.S. Nilekani studied at the Bishop Cotton Boys' School, Bangalore, and then at St. Joseph's High School in Dharwad before completing his Pre-university from Karnatak College, Dharwad. He then completed his bachelor's degree in Electrical engineering from the Indian Institute of Technology, Bombay.

Career

Information technology In 1978 he started his career at the Mumbai-based Patni Computer Systems, where he met and was interviewed by N.R. Narayana Murthy. In 1981, Nilekani, Murthy, and five others left Patni to start their own company, Infosys. Nilekani became the chief executive officer of Infosys in March 2002 and was CEO of the company through April 2007, when he relinquished his position to his colleague Kris Gopalakrishnan and became co-chairman of the board of directors. Before assuming leadership as CEO in 2002, Nilekani held various posts, including managing director, president, and chief operating officer. He was its CEO from March 2002 to April 2007. During his five-year tenure as CEO, Infosys' topline grew sixfold to $3 billion. In 2017 he returned to Infosys after the exit of CEO Vishal Sikka to become a chairman. Upon his return he changed power centre from California back to its Bengaluru headquarters. Also, such people as R. Seshasayee (a chairman and board director), Ravi Venkatesan (a co-chairman), Sikka (executive vice chairman and director), and Jeffrey Lehman and John Etchemendy (directors) resigned from their posts.

Bureaucracy Nilekani left Infosys in July 2009 to become the chairman of the Unique Identification Authority of India, a cabinet-ranking position that he entered under the invitation of Prime Minister Dr. Manmohan Singh. As chair of the UIDAI he was responsible for implementing the envisioned Multipurpose National Identity Card, or Unique Identity card (UID Card) project in India. This initiative aims to provide a unique identification number for all residents of India and will be used primarily as the basis for the efficient delivery of welfare services. The identification method will be biometric, and the drive to create this government database of the entire population of India has been called "the biggest social project on the planet." They developed Aadhaar, which is an Indian biometric ID system, a database, which contains demographic information, home addresses of Indians. In April 2017 1.14 billion Indian people got their ID number. In 2016, World Bank Chief Economist Paul Romer called Aadhaar “the most sophisticated ID programme in the world.” This program is criticized for violating people's privacy and exposing personal information. He is a member of the board of governors of the Indian Council for Research on International Economic Relations (ICRIER) and the president of NCAER. He also sits on several advisory boards, including those of the World Economic Forum Foundation and the Bombay Heritage Fund. Nilekani has appeared on The Daily Show with Jon Stewart to promote his book Imagining India: The Idea of a Renewed Nation and spoke at a TED conference in 2009 on his ideas for India's future. Nandan Nilekani played a key role in the development of the Unified Payments Interface (UPI), a system that revolutionized digital payments in India. He was instrumental in its creation while serving as the chairman of the Unique Identification Authority of India (UIDAI) and also led a committee that developed a framework for digital payments. Nilekani envisions a future where the energy sector experiences a similar transformation, drawing parallels to UPI and calling it "the next UPI".

Politics Nilekani joined Indian National Congress in March 2014 and contested from the Bangalore South constituency where he lost by 228,575 votes to BJP candidate Ananth Kumar in the 2014 Lok Sabha election. In December 2016, he joined a committee to investigate how people in India could use digital payments to a greater extent.

General election 2014 According to news reports, he was the richest candidate for the 2014 Lok Sabha elections with declared assets worth Rs 7,710 crore in his affidavit filed before the Election Commission.

EkStep Nilekani is chairman of EkStep, a non-profit literacy and numeracy platform. Set up by the Nilekanis with an initial commitment of $10 million (about Rs 82 crore), EkStep looks at solving the 'learning problem' by creating a technology-led platform to help children in improving their 'learning outcomes' quite early in their life. EkStep intends to do it using gamified apps, hosted in the Google Play Store.

Worked examples

Example 1 — a first encounter with Nandan Nilekani

Start with the simplest possible case. Write down what Nandan Nilekani claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nandan Nilekani before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nandan Nilekani ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nandan Nilekani

In research: Nandan Nilekani appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nandan Nilekani in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nandan Nilekani is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Indian philanthropists, Bishop Cotton Boys' School alumni, Businesspeople from Bengaluru, so understanding it makes those chapters shorter.
In everyday life: Look for Nandan Nilekani outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
