R amesh Jaisinghani is an Indian billionaire whose family owns and runs Polycab India, one of the country's largest and most successful manufacturers of cables and wires. The company was founded by his older brother, Inder Jaisinghani, as a small trading firm in the 1980s. The family has since built it into a massive and diversified electrical goods company. Polycab is a dominant player in the Indian market for a wide range of electrical products, from power cables and optical fiber cables to electric fans, lighting, and switches.

While his brother Inder is the chairman and managing director, Ramesh has been a key executive in the company for many years, helping to build its operations and strategy. The family's controlling stake in the publicly traded company is the source of their multi-billion dollar fortune. The company's growth has been fueled by India's massive infrastructure development and the increasing demand for electrical products from both the industrial and consumer sectors.
