1. 1 billion downloads with 5 peopleThe messaging service hit the 1 billion downloads mark on Android back in March last year, and WhatsApp co-founder and CEO Jan Koum posted in response that the team working on the Android version was just five people in total.
2. The company's co-founders were rejected by Facebook and Twitter
Both Jan Koum and Brian Acton - who earlier worked together at Yahoo - were rejected by Facebook and Twitter in interviews, before they went full-time with WhatsApp. Imagine how different the world would be if even one of those interviews had gone better.
3. You can use WhatsApp to compress images and videos
Sure you could use a dedicated photo editing app to do that, but this works great for a quick fix if you don't mind the drop in quality. Send the set of pictures and video files to one of your friends (or yourself) via WhatsApp, and then head over to the WhatsApp Media folder on Android or your Camera Roll on iOS to find the compressed versions. You can delete the originals to save space, or share the compressed images or videos through some other if you prefer.

4. WhatsApp creates user account in the form of [phone number]@s.whatsapp.net
The service runs a customised version of the open messaging standard XMPP (Extensible Messaging and Presence Protocol), which was first developed for collaboration application Jabber. That's why WhatsApp uses the ID protocol made for Jabber in the form of <[phone number]@s.whatsapp.net>
