Scale Venture Partners Invests $11 Million in PubNub Series B

PubNub, an upstart operator of a global real-time network for mobile applications, has landed an $11 million investment led by Scale Venture Partners.

The Series B investment brings PubNub’s total capital raised to north of $15 million. Scale’s Andy Vitus will join the board of directors. Relay Ventures and TiE Angels, previous investors in PubNub, also participated.

PubNub operates a global network that essentially serves as the backbone that enables real-time data feeds to mobile devices all over the world. It likes to say that its network streams three million messages a second to as many as 100 million devices every month, and is the data channel for thousands of mobile apps. It does this by operating 11 data centers around the world, and says it can reach pretty much any mobile device in the world within a quarter of a second. Its API works with browser, desktop and server and more than 50 different environments including Apple’s iOS, Google’s Android and JavaScript.

It’s an impressive claim, and its customers include Rebtel, a company that provides cheap international calls, taxi-hailing service GetTaxi and Spreecast, among others. Its network has also powered event-driven apps supporting the last two Super Bowls and the 2012 Olympic Games.
