  1. History of Whats App WhatsApp, was incorporated in 2009 by Brian Acton and Jan Koum, both former employees of Yahoo!. After Koum and Acton left Yahoo! in September 2007, the duo traveled to South America as a break from work.At one point they applied for jobs at Facebook but were rejected.For the rest of the following years Koum relied on his $400,000 savings from Yahoo!. In January 2009, after purchasing an iPhone and realizing that the App Store would soon create an industry of apps, Koum started visiting his friend Alex Fishman in West San Jose where the three would discuss "... having statuses next to individual names of the people", but this was not possible without an iPhone developer. Fishman found a Russian developer on, Igor Solomennikov, and introduced him to Koum. Koum named the app "WhatsApp" to sound like "what's up". On February 24, 2009, he incorporated WhatsApp Inc. in California. However, because early versions of WhatsApp often crashed or got stuck at a particular point, Koum felt like giving up and looking for a new job, upon which Acton encouraged him to wait for a "few more months".

  6. Business model In response to the Facebook acquisition in 2014, Slate columnist Matthew Yglesias questioned whether the company's business model of charging users $1 a year was viable in the United States in the long term. It had prospered by exploiting a "loophole" in mobile phone carriers' pricing. "Mobile phone operators aren't really selling consumers some voice service, some data service, and some SMS service", he explained. "They are selling access to the network. The different pricing schemes they come up with are just different ways of trying to maximize the value they extract from consumers." As part of that, carriers sold SMS separately. That made it easy for WhatsApp to find a way to replicate SMS using data, and then sell that to mobile customers for $1 a year. "But if WhatsApp gets big enough, then carrier strategy is going to change", he predicted. "You stop selling separate SMS plans and just have a take-it-or-leave-it overall package. And then suddenly WhatsApp isn't doing anything."The situation may have been different in countries other than the United States.
