Nandan Nilekani

Template:Infobox person

Nandan Mohanrao Nilekani (born June 2, 1955) is an Indian billionaire entrepreneur, technologist, and philanthropist who serves as the non-executive chairman of Infosys, one of India's largest information technology companies which he co-founded in 1981. He is widely recognized as the architect of Aadhaar, the world's largest biometric identification system that has enrolled over 1.3 billion Indian residents, and is credited as one of the primary visionaries behind India's digital public infrastructure revolution, including the Unified Payments Interface (UPI) and the Open Network for Digital Commerce (ONDC).

Nilekani's impact on India's technological landscape earned him a place on the TIME 100 list of the world's most influential people in 2006 and 2009, and most recently in TIME's 100 Most Influential People in AI for 2024. As of December 2025, his net worth is estimated at US$3.2 billion, making him the 100th richest person in India. He and his wife Rohini have pledged to donate more than half their wealth through The Giving Pledge.

Early life and education

Nandan Nilekani was born on June 2, 1955, in the small town of Sirsi in the Uttara Kannada district of Karnataka, India. He grew up in a middle-class Konkani-speaking family with strong intellectual roots. His father, Mohan Rao Nilekani, worked as a general manager at Mysore and Minerva Mills and subscribed to Fabian Socialist ideals that would significantly influence young Nandan's worldview and later his approach to technology for public good. His mother, Durga Nilekani, was a homemaker. He has an elder brother, Vijay Nilekani, who went on to work at the Nuclear Energy Institute in the United States.

Nilekani's early education took place across several institutions in Karnataka. He attended Bishop Cotton Boys' School in Bangalore before moving to Dharwad, where he studied at St. Joseph's High School. He completed his pre-university education at Karnataka PU College in Dharwad, demonstrating academic excellence that would pave the way for his entry into one of India's most prestigious engineering institutions.

In 1973, Nilekani secured admission to the Indian Institute of Technology Bombay, where he pursued a degree in electrical engineering. The IIT environment proved transformative - it was here that Nilekani developed not only technical expertise but also an entrepreneurial mindset and a passion for solving complex problems at scale. He graduated in 1978 with his B.Tech. Degree and immediately entered the technology industry at a time when India's software sector was in its nascent stages.

Career

Early career at Patni Computer Systems

After graduating from IIT Bombay in 1978, Nilekani joined Patni Computer Systems in Mumbai, one of India's early software companies. This position proved fateful when he was interviewed by Narayana Murthy, who was then working at Patni. The two men developed a close working relationship and shared a vision for what the Indian software industry could become. At Patni, Nilekani gained valuable experience in the software services business and began to understand the potential of providing technology services to international clients.

Co-founding Infosys

In 1981, Nilekani, Murthy, and five colleagues - S. Gopalakrishnan, S. D. Shibulal, K. Dinesh, N. S. Raghavan, and Ashok Arora - resigned from Patni to establish their own company. With just US$250 in seed capital (borrowed from Murthy's wife Sudha) and a borrowed table in a Pune apartment, they founded Infosys. Nilekani reportedly told his wife Rohini about the venture, and she invested her entire savings of ₹10,000 (approximately US$1,200 at the time) into the fledgling company - a bet that would eventually yield returns worth billions of dollars.

The early years were challenging. The founders worked out of cramped quarters, handled everything from coding to marketing, and often faced bureaucratic hurdles that were common in India's license raj era. Nilekani's role evolved as the company grew - he served as managing director, president, and chief operating officer at various stages. His ability to communicate the company's vision to international clients and his understanding of global business practices proved essential to Infosys's expansion.

CEO of Infosys (2002-2007)

In March 2002, Nilekani was appointed CEO and Managing Director of Infosys, succeeding Narayana Murthy. His five-year tenure marked a period of extraordinary growth for the company. When he took over, Infosys had annual revenues of approximately US$500 million. By the time he stepped down in April 2007, revenues had grown sixfold to approximately US$3 billion, and the company had cemented its position as one of the world's leading IT services firms.

Under Nilekani's leadership, Infosys expanded its global footprint, opened new development centers, and strengthened its reputation for corporate governance - a hallmark that distinguished Indian IT companies in global markets. The company's workforce grew substantially, and its market capitalization increased dramatically. Nilekani became known for his articulate explanations of globalization and technology's role in transforming economies, earning him invitations to speak at major international forums.

In April 2007, Nilekani transitioned from CEO to co-chairman of the board, handing operational responsibilities to his colleague Kris Gopalakrishnan. He remained closely involved with the company's strategic direction while beginning to focus on broader issues of technology and public policy.

Chairman of UIDAI and the Aadhaar project (2009-2014)

In July 2009, Nilekani accepted an invitation from Prime Minister Manmohan Singh to lead the Unique Identification Authority of India (UIDAI) as its first chairman, a position equivalent to cabinet minister rank. The assignment came with minimal guidance - as Nilekani later recounted, "All I had was one page saying, 'Give every Indian a unique ID. It didn't say how… Just, 'Do it.'"

The challenge was staggering in scope: creating a digital identity for more than a billion people in a country where many lacked birth certificates or any formal documentation. Nilekani assembled a team that included technologists, bureaucrats, and domain experts, and developed a system that would collect biometric data (all ten fingerprints and iris scans) along with demographic information to create a unique 12-digit identifier for each resident.

The Aadhaar system that emerged became the world's largest biometric identification program. By 2016, World Bank Chief Economist Paul Romer called it "the most sophisticated ID programme in the world." The system now handles approximately 80 million authentication transactions daily and has become integral to India's financial inclusion initiatives, enabling direct benefit transfers that have reduced leakages in government welfare programs.

Nilekani remained as UIDAI chairman until 2014, overseeing the enrollment of hundreds of millions of Indians. The foundation he laid would later enable other digital public infrastructure initiatives, including the Unified Payments Interface (UPI) for digital payments, which processed over US$2 trillion in transactions in 2023.

Political candidacy (2014)

In 2014, Nilekani entered electoral politics, contesting the Lok Sabha elections from the Bangalore South constituency as a candidate of the Indian National Congress. Despite his prominence and substantial campaign spending, he lost to the Bharatiya Janata Party's Ananth Kumar by a margin of approximately 230,000 votes. The defeat taught Nilekani that success in the technology world did not automatically translate to electoral politics, and he returned his focus to the private sector and public interest technology initiatives.

Return to Infosys as Chairman (2017-present)

In August 2017, Infosys faced a leadership crisis following the abrupt resignation of CEO Vishal Sikka amid a public feud between the company's founders and its board of directors. Narayana Murthy had accused the board of corporate governance lapses, and investor confidence had been shaken. The board turned to Nilekani as a unifying figure who commanded respect from all stakeholders.

Nilekani accepted the position of non-executive chairman, returning to the company he had co-founded 36 years earlier. His return was seen as a stabilizing force - he moved the company's power center back from California to its Bangalore headquarters, helped recruit Salil Parekh as the new CEO, and worked to restore the company's reputation for ethical governance. Under his renewed chairmanship, Infosys has continued to grow, with revenues exceeding US$18 billion annually.

Digital public infrastructure advocacy

Beyond his corporate roles, Nilekani has been instrumental in conceptualizing and advocating for India's digital public infrastructure stack. He served as the founding chairman of the National Payments Corporation of India (NPCI), which developed UPI. He has championed the India Stack - a set of open APIs and digital public goods that includes Aadhaar, UPI, DigiLocker, and other systems - as a model for other developing countries.

In January 2023, he was appointed co-chair of the G20 Task Force on Digital Public Infrastructure for Economic Transformation, Financial Inclusion, and Development, working to share India's experience with other nations.

In 2024, Nilekani launched Adbhut India, an open-source AI nonprofit designed to build India's linguistic AI infrastructure. The initiative aims to bridge digital divides by enabling access to large language models in Indian vernacular languages, recognizing that much of the world's AI development has focused on English and other major Western languages.

Controversies

Aadhaar privacy concerns

The Aadhaar program, while widely credited with enabling financial inclusion and reducing welfare fraud, has faced sustained criticism from privacy advocates. Critics have argued that the collection of biometric data from 1.3 billion people creates surveillance risks and exposes citizens to identity theft. In 2018, former US Central Intelligence Agency contractor and whistleblower Edward Snowden described Aadhaar as "a mass surveillance system" and warned that "if not fixed now then it will lead to the death of all civil rights of Indians."

Nilekani has consistently defended the system, arguing that Aadhaar is "just an ID" and does not qualify as a surveillance tool since there is no central database that stores all transaction data. He has acknowledged that privacy and cybersecurity concerns are "par for the course" in driving digital transformation at scale while maintaining that appropriate safeguards exist.

In 2018, the Supreme Court of India upheld Aadhaar's constitutionality in a landmark judgment but imposed limits on its mandatory use, prohibiting private entities from requiring Aadhaar for services and restricting its use in school admissions and other contexts.

Personal data leak incident

In an ironic twist for the architect of India's digital identity system, Nilekani himself became a victim of data exposure. In April 2014, he tweeted a picture of his own Aadhaar card, blacking out the first eight digits of his 12-digit number but failing to obscure the QR code that contained his full personal demographic information. His data remained accessible online for years afterward, highlighting the vulnerabilities inherent in digital identity systems that he had helped create.

Infosys founders-board conflict

Nilekani's 2017 return to Infosys came amid a bitter dispute between the company's founders, led by Narayana Murthy, and its board of directors. Murthy had publicly criticized the board over the severance package given to departing CFO Rajiv Bansal and the salary paid to CEO Vishal Sikka. While Nilekani's return helped resolve the immediate crisis, questions lingered about corporate governance and the appropriate role of founders in companies they had long departed from management.

Personal life

Nandan Nilekani met his future wife, Rohini Soman, at a quiz competition at her college in Mumbai in 1977. Both were intellectually driven young people - Rohini was studying French literature at Elphinstone College while Nandan was completing his engineering degree. They married in 1978, just before Nilekani joined Patni Computer Systems.

When Infosys was founded in 1981, Rohini invested her entire savings of ₹10,000 into the venture. She has since become a prominent philanthropist and author in her own right, founding Arghyam Foundation in 2001, which focuses on water and sanitation issues, and co-founding EkStep, a nonprofit education platform. She was named one of Asia's Heroes of Philanthropy by Forbes in 2010 and 2014, and in 2023 was ranked among India's top philanthropists, having donated approximately ₹170 crore (roughly US$20 million) that year. She is the author of several books, including the novel Stillborn (1998).

The couple has two children, both of whom attended Yale University. Their daughter, Janhavi Nilekani, is married to Shray Chandra. Their son, Nihar Nilekani, works in the technology sector.

In 2017, Nandan and Rohini Nilekani joined The Giving Pledge, the initiative founded by Warren Buffett and Bill Gates, committing to donate more than half of their wealth to philanthropic causes. In explaining their decision, they noted: "We see inequality is increasing sharply in most countries."

The family resides in Bangalore, where both Nandan and Rohini remain actively involved in various nonprofit initiatives focused on technology, education, water, and environmental sustainability.

Business philosophy

Nilekani is known for his belief in technology as a tool for solving large-scale societal problems. His 2009 book Imagining India: The Idea of a Renewed Nation outlined his vision for how technology, education, and urbanization could transform India. He has been a consistent advocate for open-source approaches to public infrastructure, arguing that government-built digital platforms should be available as public goods rather than proprietary systems.

His philosophy of "population-scale technology" - building systems that can serve a billion users from day one - has influenced how India approaches digital infrastructure. This thinking is evident in systems like Aadhaar and UPI, which were designed for massive scale from their inception rather than growing incrementally.
