Kumar Mangalam Birla, chairman of the Aditya Birla Group, is the seventh richest Indian with a net worth of $6.8 billion.
After his father's death, Kumar Mangalam, then in his 20s, took over Aditya Vikram Birla's legendary mantle, brought about several changes in financial practices and the power centres within the group, and gave it unique direction.
Unusually for a Birla company, his managers could question his leadership style.
Among its major companies in India are Grasim, Hindalco, UltraTech Cement, Aditya Birla Nuvo and Idea Cellular. The Aditya Birla Group is also India's first truly multinational corporation.
The Rs 40,000 crore group has 82,000 employees. According to Kumar Mangalam, values act as the bedrock of an organisation.
Kumar Mangalam will turn 40 next year, possibly a catalyst for another shift in this visionary's business objectives.
