The idea started off as an app that would display statuses in a phone's Contacts menu, showing if a person was at work or on a call.<a href="#cite_note-History-26">[26]</a> Their discussions often took place at the home of Koum's Russian friend Alex Fishman in West San Jose. They realized that to take the idea further, they would need an iPhone developer. Fishman visited RentACoder.com, found Russian developer Igor Solomennikov, and introduced him to Koum.<a href="#cite_note-History-26">[26]</a> Koum named the app WhatsApp to sound like "<a href="https://en.wiktionary.org/wiki/what%27s_up" class="extiw" title="wikt:what's up">what's up</a>". On February 24, 2009, he incorporated<a href="#cite_note-Article_of_Incorporation-61">[61]</a> WhatsApp Inc. in California. However, when early versions of WhatsApp kept <a href="/wiki/Crash_(computing)" title="Crash (computing)">crashing</a>, Koum considered giving up and looking for a new job. Acton encouraged him to wait for a "few more months".<a href="#cite_note-History-26">[26]</a> In June 2009, when the app had been downloaded by only a handful of Fishman's Russian-speaking friends, Apple launched <a href="/wiki/Push_technology" title="Push technology">push notifications</a>, allowing users to be pinged even when not using the app. Koum updated WhatsApp so that everyone in the user's network would be notified when a user's status changed. This new facility, to Koum's surprise, was used by users to ping "each other with jokey custom statuses like, 'I woke up late' or 'I'm on my way.'"<a href="#cite_note-History-26">[26]</a> Fishman said "At some point it sort of became instant messaging".<a href="#cite_note-History-26">[26]</a> WhatsApp 2.0, released for <a href="/wiki/IPhone" title="IPhone">iPhone</a> in August 2009, featured a purpose-designed messaging component; the number of active users suddenly increased to 250,000. Although Acton was working on another startup idea, he decided to join the company.<a href="#cite_note-History-26">[26]</a> In October 2009, Acton persuaded five former friends at Yahoo! to invest $250,000 in <a href="/wiki/Seed_funding" class="mw-redirect" title="Seed funding">seed funding</a>, and Acton became a co-founder and was given a stake. He officially joined WhatsApp on November 1.<a href="#cite_note-History-26">[26]</a> Koum then hired a friend in Los Angeles, Chris Peiffer, to develop a <a href="/wiki/BlackBerry" title="BlackBerry">BlackBerry</a> version, which arrived two months later.<a href="#cite_note-History-26">[26]</a> Subsequently, WhatsApp for Symbian OS was added in May 2010, and for Android OS in August 2010.<a href="#cite_note-MyUser_Venturebeat.com_June_5_2016c-28">[28]</a> In 2010 Google made multiple acquisition offers for WhatsApp, which were all declined.<a href="#cite_note-Neeraj-62">[62]</a> To cover the cost of sending verification texts to users, WhatsApp was changed from a free service to a paid one. In December 2009, the ability to send photos was added to the iOS version.

These could be a social networking service like Facebook, a messaging service, maybe search and other things like weather. Providing a bundle of these free of charge to users will work like a gateway drug of sorts – users who may be able to afford data services and phones these days just don't see the point of why they would pay for those data services. This would give them some context for why they are important, and that will lead them to pay for more services like this – or so the hope goes.<a href="#cite_note-techcrunch-whatsapp-io-79">[79]</a></blockquote> Three days after announcing the Facebook purchase, Koum said they were working to introduce voice calls.
