Lakshmi Mittal grew up in Kolkata, where he gained early experience in his father’s steel business before founding his own steel mill in Indonesia in his twenties. By adopting mini-mill technology and electric arc furnaces, Lakshmi Mittal produced steel more efficiently than traditional methods and began acquiring underperforming state-owned mills around the world, setting him on his path to becoming a billionaire.

Journalists Zing Tsjeng and Simon Jack trace his journey of entrepreneurship from one mill in Indonesia to leading ArcelorMittal, the world’s largest steelmaker. They explore how Lakshmi Mittal navigated a split from the family business, executed bold global acquisitions, and reshaped a fragmented industry into a profitable, consolidated powerhouse.
