Investors gave $1 million to a messaging app that just sends "Yo"

Or Arbel spent just eight hours creating a messaging app that sends nothing but “Yo” – now he’s on his way from Israel to San Francisco to work full time as a CEO of a $1.2 million dollar company. The app, Yo, is unique in that it does very little: send a “Yo” or send a “YoYo” with a double tap. That’s all, folks.

Yo, the app, is the hot app of the moment. It has 50,000 users who have sent 4 million Yo’s.
