“WhatsApp is on a path to connect 1 billion people. The services that reach that milestone are all incredibly valuable,” said Facebook chief Mark Zuckerberg in the release. “I’ve known [WhatsApp cofounder] Jan [Koum] for a long time, and I’m excited to partner with him and his team to make the world more open and connected.”

WhatsApp’s massive userbase largely exists outside of the U.S., which makes this deal Facebook’s ticket to speedier international expansion. As for WhatsApp, the messaging service has yet to truly catch on in the U.S. Facebook can change that.

This deal also grants WhatsApp’s team $3 billion in stock that will vest over the course of four years.

With this announcement, Facebook also shared noteworthy stats that reveal WhatsApp’s current size. Currently, 450 million people use WhatsApp per month, with 1 million users added daily.

As in its Instagram acquisition, Facebook claims that “WhatsApp’s brand will be maintained” and “its headquarters will remain in Mountain View, Calif.”
