<P> 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 RentACoder.com , 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 '' . </P>
