WhatsApp was founded by the former emlployees of Yahoo! – Brian Acton and Jan Koum and launched globally in 2009. Whatsapp Messenger has not only replaced the SMS services globally but has been steadfast in its growth in this space. Now, the mobile messaging space is indeed crowded where many apps have gained the leading position at regional levels. For instance, Wechat  is very popular in China

In April 2015, co-founder and CEO Jan Koum announced that the messaging app has more than 800 million monthly active users(MAUs). Whatsapp almost doubled its MAUs since its inception into Facebook in February 2014 for a humongous amount of USD 16 billion.(source: Business Insider)

This remarkable growth numbers for Whatsapp has also brought obstacles in its growth path. The messaging app delayed New year messages by around minutes. Thousands of users globally including the ones at TheNextWeb faced the issue of connecting with the service.
