One phone CALL SPARKED A VOICE CHANNEL REVOLUTION

It all started when founder Vijay Balasubramaniyan was traveling in India and tried to order a new suit from a local tailor. His bank flagged the international transaction as suspicious and tried to call him to verify the purchase, but the bank couldn’t prove its identity over the phone. Vijay also had no way to prove his identity to the bank. As the bank cancelled his order, Vijay promised himself he would find a better way for people to authenticate over the phone.
