Popular mobile messaging service WhatsApp claims to have surpassed 430 million active users. Co-founder and CEO Jan Koum says 30 million are new users and some 50 billion messages are exchanged daily. This makes WhatsApp one of the biggest rivals to SMS. Koum says the service has more users on Android than on any other platform. Taking a dig at picture messaging service Snapchat and Tencent's WeChat, he says the company will not focus on disappearing photos and games. He also says WhatsApp will remain ad-free. He assures that the service does not collect users' personal information in any form.
