Bharti Airtel's Chairman Sunil Bharti Mittal's 33-year-old son Kavin Bharti Mittal in an interview said, "I'm very proud to be my dad's son." He added, "Yes, there are some connotations that come with being a billionaire's son, but there are people who'd kill to be my dad’s son." Kavin, who founded Hike Messenger, shut down the service earlier this year.
