Who created WhatsApp?

WhatsApp was founded by Jan Koum and Brian Acton who had previously spent 20 years combined at Yahoo. WhatsApp joined Facebook in 2014 but continues to operate as a separate app with a laser focus on building a messaging service that works fast and reliably anywhere in the world. The service was created by WhatsApp Inc. of Mountain View, California, which was acquired by Facebook in February 2014 for approximately US$19.3 billion. WhatsApp is a free messaging and calling app that allows users to communicate with friends, family, and businesses. It's available on many devices, including smartphones Mac, and Windows PC. WhatsApp gives you a no-cost, easy-to-use way to connect with friends and family on your mobile phone while ensuring robust security measures that protect your conversation privacy. All you need is a cellular data connection or WiFi.
