WhatsApp CEO Jan Koum has revealed that the messaging service is being used by 700 million people every month, up from 600 million in August.
Koum also wrote in a Facebook post that users are sending 30 billion messages per day.
The figure makes the messaging app one of the world’s largest social networks, bigger than Twitter’s 284 million or even the photo-sharing service Instagram, which counted 300 million users last month. Facebook itself, however, is still bigger, and tallies 1.3 billion users signing in every month.
The latest numbers could help Facebook placate investors’ fears about its acquisition strategy, despite the $19 billion purchase price being one of the largest deals in the history of Silicon Valley.
Facebook has, however, begun to feel pressure from investors struggling to accept CEO Mark Zuckerberg’s view that his growing list of acquired businesses and services won’t become meaningful until they hit the 1 billion mark.
