WhatsApp continues to surge, gaining 100 million new users in just four months

WhatsApp cofounder and CEO Jan Koum has announced that the messaging app has reached 700-million monthly active users, with some 30-billion messages sent every day.

Koum wrote, “Today, we’re thrilled to share that WhatsApp has more than 700 million monthly active users. Additionally, every day our users now send over 30 billion messages.”

In the post, WhatsApp’s Koum vowed to continue improving the app. Last year, WhatsApp added encryption for messages sent between its millions of Android users, making one of the safest messaging apps. That feature scrambles data to prevent messages from being hacked or monitored.

This makes WhatsApp one of the world’s largest social networks. It beats by far Twitter’s 284 million and Instagram which has 300 million users last month.

In August last year, WhatsApp reached 600-million monthly active users. The rise if it continues at the pace it is going WhatsApp will reach a billion monthly users before the year ends. A figure that will make Mark Zuckerberg happy. Last year he had said that “Over a five-year time frame. We have a number of services which we think are well on their way to reaching 1 billion people: WhatsApp, Instagram and search are a number of them. And once we get to that scale, then we think that they will start to become meaningful businesses in their own right.”

“We’re grateful that so many of you are using WhatsApp to stay in touch with your friends and family, business colleagues and classmates,” Koum wrote.

A WhatsApp spokesman declined to say how many users are paying customers, or whether its growth has met Facebook’s expectations.
