You can now send the word 'yo' to your friends who have discovered newfound fame and fortune by a simple messaging app. San Francisco-based startup Yo, which got its start in Tel Aviv and moved to California after becoming a hit in Israel, boasted new backers on Friday as reports estimated its value as high as $10 million.
Betaworks announced that it is part of a recently wrapped Yo funding round, due in part to a fascination with the potential of simple tools for single word smartphone notifications such as "yes" or "no."
The Yo app has been woven into communications at Betaworks, according to founder and chief executive John Borthwick.
"We Yo with co-workers alerting them that a meeting is starting; I Yo with my wife as a 'hi' during a busy day," Borthwick said in an online post announcing the investment.
"I Yo with friends, without any more expectation or need than a Yo back."
US media reports indicated Yo raised $1.5 million in a funding round that including backing from founder's of China-based Tencent as well as Mashable founder Pete Cashmore.
"People think it's just an app that says 'Yo.' But it's really not," Arbel told The New York Times.
Convinced his app has big prospects in line, he left his job as chief technology officer of stock trading platform Stox, which he helped launch last year, and moved from Tel Aviv to San Francisco to focus on Yo.
Arbel said the app could allow newspapers and blogs to notify subscribers that a new article has been published or posted, using a Yo.
Yo took advantage of World Cup frenzy by letting users sign up to get Yo notifications when goals were scored.
Reviews on Apple's App Store were positive, but some delved into sarcasm.
"Yo cured my cancer! Yo ended world hunger, Yo also helped me find the women of my dreams because when I yo'd her for the first time she asked me if I wanted to mate and produce spawns, yo is the reason I live and the reason I wake up in the morning," read a review featured along with a description at the App Store on Friday.
Applications available free for iOS or Android powered devices have reportedly been downloaded more than two million times and is used to fire off "yo" a similar number of times daily.
