WhatsApp was founded in 2009 by Brian Acton and Jan Koum, former employees of Yahoo. After leaving Yahoo in 2007, Acton and Koum took a year off to travel around South America. It was during this time that they began discussing the possibilities of developing a mobile messaging app that would allow people to easily communicate anywhere in the world. Upon returning from their travels, Acton and Koum began developing WhatsApp in June 2009.
The Early Stages of WhatsApp’s Development
Acton and Koum started working on WhatsApp in the spring of 2009. At the time, the App Store had just launched the year before, opening up exciting new opportunities for mobile apps. However, the existing text messaging apps at the time had limitations in terms of reliability and functionality. Acton and Koum recognized there was room for an app that could provide free, internet-based messaging on mobile devices. After months of development, WhatsApp launched in November 2009 exclusively on the Apple App Store for the iPhone. The initial release allowed users to message each other for free with push notifications to signal new messages.
2009: WhatsApp is Founded
WhatsApp was founded in 2009 by Brian Acton and Jan Koum. The founders started working on the app in spring 2009. After months of development, WhatsApp launched in November 2009 as one of the first messaging apps in the App Store.
Focusing on User Experience
From the beginning, Acton and Koum focused on providing a seamless user experience. They wanted WhatsApp to be fast, reliable, and available internationally. To achieve this, they designed WhatsApp to use the same internet data plan that users already had on their smartphones instead of relying on traditional SMS networks. This helped maximize performance and let WhatsApp instantly reach users worldwide. The app also featured a status indicator that showed when messages were delivered and read for improved reliability.
WhatsApp’s Early Growth and Expansion
After launching exclusively on iOS, WhatsApp became available on Android in August 2010 and BlackBerry OS in August 2011. By early 2011, WhatsApp had over 1 million active users. The app’s popularity continued to surge as people appreciated the ad-free experience, ease of use, and reliability of sending messages internationally. WhatsApp grew from 10 million active users in 2011 to 100 million in 2013. Such tremendous growth came from word of mouth recommendations and delivering an essential communication service.
2010-2011: User Base Reaches 1 Million
Following WhatsApp’s iOS launch in 2009, an Android app arrived in 2010. A version for BlackBerry OS followed in 2011. During this period, WhatsApp’s active user base grew rapidly, surpassing 1 million users by early 2011.
Supporting More Platforms
A key part of WhatsApp’s early growth was supporting more mobile platforms. Releasing Android and BlackBerry OS apps in 2010-2011 allowed WhatsApp to reach millions more users worldwide across different devices. This strategy helped fuel the app’s initial viral growth.
Focus on Organic Growth
Unlike many companies, WhatsApp did not rely on traditional advertising in its early stages. Instead, the app grew organically via word of mouth. WhatsApp focused on delivering an essential communication service that people wanted to recommend to their friends and family.
Major Developments at WhatsApp
By early 2013, WhatsApp had amassed over 200 million active users. The app’s runaway success attracted attention, and Facebook acquired WhatsApp for $19 billion in February 2014. Despite the massive acquisition, WhatsApp continued expanding its product offerings after joining Facebook.
2013: User Base Reaches 200 Million
In early 2013, WhatsApp reached another major milestone by crossing 200 million monthly active users. The app’s tremendous growth stemmed from its simplicity, universality, and utility as a communication service.
2014: Facebook Acquires WhatsApp
In February 2014, Facebook acquired WhatsApp for approximately $19 billion. The record-breaking acquisition demonstrated WhatsApp’s immense value in connecting people globally. However, WhatsApp maintained its brand and product following the acquisition.
Post-Acquisition Product Development
After the Facebook acquisition, WhatsApp continued improving features and expanding to new platforms. Major additions included voice and video calling, WhatsApp Web for messaging from desktop browsers, and business tools. These helped strengthen WhatsApp’s position as a top messaging app.
Recent Statistics and Milestones
As of 2023, WhatsApp has over 2 billion monthly active users worldwide. It has become one of the most popular apps ever, seeing strong growth in countries like India and Brazil. WhatsApp’s global success demonstrates the founders’ vision of creating an essential communication service.

Continued Global Growth
With over 2 billion users already, WhatsApp still has room to grow, particularly across developing markets in Africa, Asia, and Latin America where smartphone adoption continues rising.
Addressing Misinformation
