Shivakumar Ganesan, 

‘Shivku’ started Exotel as a company offering virtual phone numbers and IVR solutions. Between 2014 and 2015, call volumes grew from 56 million to nearly half a billion. The company handles some two million calls a day. Key to those numbers is the rapid adoption of Internet-based services. Companies like Uber, Ola, Urban Ladder, and Zivame are among those who use Exotel to enable their customers to make calls while keeping their numbers private. Shivku plans to get into newer arenas—such as emotion detection—in the near future.
