Behind many of the products Indians use every day are billionaire-led companies headquartered in the country's financial capital.

Maharashtra continues to dominate India's corporate landscape, with Mumbai-based industrialists running empires across telecom, retail, pharmaceuticals, cement and consumer goods.
