Businesspersons know that sticking close to what they know well generates the best return. So, apart from investing in their own business, they are now backing other promising entrepreneurs. And why not, they know the drill and can leverage their experience to scale up their portfolio companies. Take the case of India’s youngest billionaire, Vijay Shekhar Sharma, who at the age of 41 is estimated to have a net worth of Rs.130 billion. He says that he doesn’t really have a structured approach to wealth creation. “Get me a great idea with an enterprising guy behind it, and you will have me hooked,” he says. He has invested in around 25 other start-ups including Dimension NXG, GOQii, Unacademy and InnerChef, apart from being a limited partner in a couple of venture funds. Similarly, serial entrepreneur K Ganesh and his wife Meena Ganesh launched GrowthStory, an entrepreneurship platform that promotes and runs start-ups. Today, they run 14 companies in the consumer-internet space including online grocery unicorn Bigbasket, online jeweller BlueStone, home healthcare provider Portea Medical and online food ordering platform FreshMenu, collectively valued at around $2 billion.
