A woman named Nandini Jain confronted Zerodha co-founder and billionaire Nikhil Kamath about why he never replied to her 6.5-month-old email. "You...often reply to emails that say 'Here's 3 things I can do for you'...I did that same thing," she said at an event. "I'm sorry," Kamath responded, drawing laughter and added that it gets hard to read many emails.
