Bill is the VP of Software Development at Justin.tv.  As the first engineering employee, he wrote and currently maintains the site's highly scalable chat system.  Bill has been passionate about solving interesting problems with computers ever since he taught himself to program on a ZX81 at age nine.  After earning his PhD in Mathematics, he moved from the UK to the Silicon Valley in 2003 to be a part of the latest innovations in technology.  In his spare time, he's created a search engine for Lisp documentation, a multiplayer crossword game, an MRI explorer, and is now building a robotic xylophone.  He enjoys learning about music, hiking, kayaking, and building and  flying model planes.  Most recently, Bill lead the team which created the iPhone broadcaster app for Justin.tv.  Last month, Bill assisted in the delivery of his daughter and now spends much of his spare time learning to be a dad. 

Ammon grew up on a farm in western New York State, where he had a cow named Snork Maiden. At age 14, however, he got tired of milking, and turned to QBasic. So began his love-affair with algorithms (or perhaps just explosive bananas). He did undergraduate in computer science and Spanish at SUNY Potsdam, with a year in León, Spain to study CS in Spanish. For a final project, he wrote a parallel implementation of the multiple polynomial quadratic sieve factoring algorithm. Justin.tv was his first job out of school. He began by hacking on Usher, the brain of the Justin.tv video system, where he's built inter-datacenter stream replication and flash crowd detection, and added on-demand transcoding to support mobile viewers.  He is now hard at work on Socialcam for iPhone.  You can read more about Ammon's first year at JTV here.  

Before co-founding Justin.tv, Kyle was studying Computer Science and Electrical Engineering at MIT.  He previously worked at Panasonic Boston Laboratory, Brontes Technologies (Acquired by 3M), and iRobot.  At Justin.tv, he is Chief Product Officer and is responsible for all product strategy and development.  He also held the position of VP Engineering, during which he grew Justin.tv's infrastructure from 2 servers to several hundred servers and wrote much of the original software that powers the most scalable and reliable UGC live video platform on the web. 

Rhys Hiltner's background includes a range of hardware and software projects. During undergrad at MIT, he built a guitar teaching game capable of detecting chords played in real time, and a fast digital stabilization system for an octave-spanning optical frequency comb. He graduated in 2009 with an SB in Physics and an SB in Electrical Engineering and Computer Science. At Justin.tv, Rhys writes the Android broadcasting app, which adjusts the video quality automatically in response to network conditions.
