Part I — The story
The story
Dhirubhai Ambani rose from a schoolteacher's son who worked as a petrol-pump attendant in Yemen to build Reliance Industries into India's largest private company — one of the great rags-to-riches stories in business history. Starting in textiles, he built an empire spanning petrochemicals, refining, and beyond, with a genius for scale, vertical integration, and backward integration: whenever he depended on a supplier, he would build the capacity to make it himself, climbing up the value chain relentlessly.
Ambani's other masterstroke was bringing ordinary Indians into the equity markets. He took Reliance public and evangelised share ownership to the middle class on an unprecedented scale, creating millions of shareholders and a vast base of patient capital. Operating shrewdly within — and around — India's restrictive 'licence raj', he mastered scale, ambition, and capital-raising. He is a study in relentless vertical integration, in thinking at enormous scale, and in democratising capital to fund audacious growth.
