WhatsApp was the brain child of Brian Acton and Jan Koum who met whilst working at Yahoo! in 1997. The two college graduates became friends and in 2009 they decided they wanted a piece of the booming tech scene, launching WhatsApp which they had designed for use on Apple’s iPhone.
The product was initially designed to track users’ work statuses and to show availability during working hours. However it soon developed into a messaging platform. The platform secured $250,000 in seed funding and proceeded to be available for both Blackberry and Android. Initially created as a payed for product it switched to a free model as its popularity increased.
WhatsApp continued to grow in popularity largely due to the fact it was able to communicate across different types of devices, such as Android to Apple as well as internationally. Facebook acquired the company in 2014 for $19 billion. It is now one of the biggest communication platforms in the world.
