She chairs HCL, the technology group her father Shiv Nadar founded. That makes Roshni Nadar Malhotra one of the most powerful women in Indian business, and one of the first to lead a major listed Indian IT company at all.

Inherited chairs are often ceremonial. This one is not. She has been active in the group's governance and strategy, steering a company that competes globally across IT services, software and engineering — a business with no tolerance for a figurehead at the top.

Inheriting an empire is easy to announce and hard to earn. She set out to earn it.

The Shiv Nadar Foundation is the other half of the work. Money into education and the arts, and institutions built to keep running long after whoever funded them has moved on.

Her visibility matters in an industry where women are still scarce at the top table. Running a family empire while holding a distinct public position on education and conservation is a model of Indian corporate leadership that did not really exist before.
