In 1978, Nilekani joined Patni Computer Systems in Mumbai and met N.R. Narayana Murthy. Together, they co-founded Infosys with other 6 members in 1981.

He was promoted to President and COO, then to CEO, in 2002 and led Infosys until 2007, when it achieved global status with revenue exceeding $4 billion. As a non-executive chairman since 2017, he has guided its market cap to trillions. 

From beginning with just ₹10,000 in personal savings to becoming a known brand, he has covered a long yet inspiring journey.   

During his tenure as CEO, from 2002 to 2007, Infosys witnessed explosive growth:

• Revenue: The company’s topline sixfold, reaching $3 billion by the time he stepped down as CEO.

Nandan Nilekani: The Mind behind Aadhaar and Digital India

When Nilekani was appointed as the founding chairman of UIDAI in 2009, he launched Aadhaar to provide unique identities and ID cards to the Indian population. 

Over 600 million enrollments were completed at the 25,000+ Aadhaar centres by 2014, and today 1.3 billion Indians hold Aadhaar cards as their proof of identity.

In January 2025, the graph showed an increase of up to 32% in authentications year over year. Aadhaar-enabled 284 crore authentications, fueling digital services like direct benefit transfers and saving ₹2.5 lakh crore in leakages.  

Nilekani ensured that Aadhaar was seen by numerous government and private institutions as their own strategic goals. But the RBI saw it as a path to financial involvement for India’s 700 million unbanked.

Public sector oil companies viewed it as a means to eliminate fraudulent customers who were taking advantage of subsidies. The state government, on the other hand, saw it as a platform to devise better social welfare programs. 

Aadhaar: The Identity of Billions

In 2009, Nilekani took a step that remains extraordinary in Indian corporate history. He resigned from Infosys to accept a cabinet-rank position as the chairman of the Unique Identification Authority of India (UIDAI).  

He later returned to Infosys as non-executive chairman in 2017 to stabilise the company and reaffirm its founding principles. 

However, the challenge was massive. To provide a biometric-based unique identity to over 1.2 billion Indian residents, many of whom had no formal identification. 

Aadhaar has become the foundation for Digital India, enabling the Jan-Dhan-Aadhaar-Mobile “JAM Trinity.” This allowed for Direct Benefit Transfer (DBT), ensuring that welfare subsidies reached the intended poor directly into their bank accounts.  

Aadhaar in numbers (source: Forbes India):

• Total enrollments received at UIDAI: 565 million
• Number of UIDs generated: 430 million
• Number of enrollments per month: 30 to 35 million
• Number of authentications during the last five months: 10 million
• Number of authentications per day as of now: 100,000
• Success percentage of the authentication system in the field (without iris-scanning): 91%
• False positives: None reported

Vision and Implementation of Aadhaar

Aadhaar was visualised not just as an identity card, but as a foundational digit infrastructure to enable incorporation and service delivery at scale.

• Aadhaar generates 12-digit unique IDs tied to biometric data, including fingerprints and iris scans.

• The system has enrolment of over 1.3 billion residents, making it the largest biometric database in the world. 

• Aadhaar IDs are used over 80 million times per day for authentication, Know Your Customer (KYC), and service access.  

Impact on governance and public services

Aadhaar card is not only for identification, but has become the backbone for:

• Direct Benefit Transfer (DBT) is a system that transfers government subsidies directly to people in need and eliminates intermediaries.

• Removing duplicate or fake beneficiaries saves the government billions of dollars. Nandan Nilekani himself has cited savings of roughly $9 billion by reducing fraud in welfare programs.

• Enabling over 500 million Aadhaar-linked bank accounts, which facilitated more than $12 billion of real-time government transfers. 

Although Aadhaar has become a technological triumph, it also generates debates on:

• Concerns over privacy, data protection, and misuse of the biometric data of individuals were raised by activists and analysts.

• Supreme Court sustained the Aadhaar card’s validity, but also applied limitations on the mandatory use of Aadhaar to protect the rights of individuals. 

Despite these challenges, Aadhaar remains central to India’s digital infrastructure and public service ecosystem. Nilekani converted what was initially a disadvantage (UIDAI was not authorised by the Parliament) into a life-changing event. 

His aim of giving every citizen a unique identity is successful, as we can see today, every individual has their own Aadhaar ID card.
