Voxer
We launched Voxer in 2011 and have since become one of the fastest growing voice applications in the world. What we've built is already an important part of the daily lives of millions of people.
We're a surprisingly small team doing this. Only about a dozen engineers who previously worked at Danger, Android, Apple &#38; Twitter. We helped build things like redis for node.js and are contributors to the node.js community. Voxer is built using node.js, Riak and Redis.
