WhatsApp now has more than 400 million monthly users, according to a blog post published by the company’s CEO Jan Koum. Even more stunning: Koum says his company added 100 million monthly active users in the last four months.
To put that figure in perspective, we can look at a few other popular services. Facebook has about 1.19 billion monthly active users, Google+ has about 540 million monthly active users, and Twitter has somewhere slightly above 200 million monthly active users. Considering that WhatsApp isn’t a social network, but rather a simple text messaging tool, its figures are particularly impressive. Koum takes pride in the simplicity of it service, too.
“WhatsApp has just 50 employees, and most of us are engineers,” he explained. “We’ve arrived at this point without spending a dollar on targeted ads or big marketing campaigns. We’re here because of all the people who share their WhatsApp stories with co-workers, friends, and loved ones – stories we love to hear.”
WhatsApp’s popularity can also be attributed to its wide reach. It’s available for iOS, Android, BlackBerry, Symbian and Windows Phone, which means it can run on pretty much any modern smartphone in the world. The company will likely face increased competition, however, as Facebook and Instagram, among others, work to create more robust experiences.
