G opikishan Damani is an Indian billionaire investor and a key member of the family that controls the successful supermarket chain, DMart. He is the brother of Radhakishan Damani, the famously astute investor and founder of DMart. While his brother Radhakishan is the visionary founder and public face, Gopikishan has been a crucial partner and a major shareholder in the enterprise from its early days.

DMart has become a powerhouse in Indian retail through its relentless focus on a simple, low-cost, high-volume business model, often compared to Walmart's early strategy. The company owns most of its stores, which helps to control costs, and is known for its operational efficiency. Gopikishan's wealth is derived from his significant stake in the parent company of DMart, Avenue Supermarts, which held a blockbuster initial public offering in 2017. Like his brother, he is known for being extremely private and media-shy.
