Within the first ten days of launching one year ago, the mobile video phone service Tango had one million users. As it celebrated its first anniversary last Friday, the Palo Alto-based startup counted 23 million registered subscribers to its free service, all of them using the company’s mobile apps.
Now Tango has added a PC product as well, and Microsoft is promoting Tango on its W-7 Mango platform. People can call each other from PCs, iPhones, the iPod touch, the iPad, and hundreds of Android phones and tablets.
The move to embrace the PC market would seem to be a direct swipe at Skype, the giant Internet phone service. Recently purchased by Microsoft, Skype has had trouble adapting to the mobile market, an opportunity that has been the central focus of Tango’s efforts.
“We are a communication services company and we are mobile first,” says co-founder and CTO Eric Setton. “But we initially underestimated the demand for video calls over the PC.”
