BLOOMBERG - Feb 19 - Kavin Bharti Mittal, a scion of the family behind India's second-biggest wireless operator, is planning to revive his struggling technology startup more than four years after it was valued at $1.4B by backers including Softbank Group Corp. Since attaining unicorn status in 2016, New Delhi-based Hike Pvt. has suffered a string of setbacks. In a bid to rekindle growth, he's now betting on a Facebook-like new social networking platform that promises to weed out "creeps" and "fake profiles" as well as a gaming app that aims to tap rising demand in the world's second-most populous country.
