25 most powerful people in business

Some are empire builders. Others are hired guns. But if they truly have world-class oomph, they're on Fortune's subjective - yet really quite accurate - list of the most powerful businesspeople in the world.

Lakshmi Mittal
14. Lakshmi Mittal
Had Lakshmi Mittal, 57, remained in his native India and joined the family steel company, odds are he'd merely be a prosperous local businessman. Instead he set out on his own and became the Andrew Carnegie of our era, with operations in more than 60 countries, 320,000 employees - and a personal fortune of more than $40 billion. He built his empire on a bet that steel had a great future for someone who could achieve sufficient scale. After purchasing former state-owned companies in Eastern Europe, Mittal bought into the U.S. in 2004 and last year won a bruising battle for Europe's Arcelor. Today his company is three times the size of its nearest competitor, and Mittal has become a symbol of globalization. --Peter Gumbel
