As more and more businesses are looking to join the chatbot bandwagon to grow their reach and improve customer engagement, the real question still remains, “which messaging channel should we choose?”. Although there are many factors that influence this decision, one of them is the number of users on that messaging channel. One such messaging channel with almost 900 million registered users is Viber, providing a great opportunity for businesses to have greater reach to the customers.

Viber was founded in Israel in 2010 and since then it has seen a consistent growth in its user base and is currently featured in the top 10 most used messaging apps. As of December 2016, it had 260 million monthly active users. Over the course of its journey, Viber has always kept pace with the competition bringing in tons of features like video calls, group chats, end to end encryption etc.

With the growing popularity of chatbots, Viber launched Public accounts in November 2016,  a new account for businesses to connect with their users. Since then more than 1,000 public accounts have been created on Viber with more businesses joining in.
