While working at chess.net, Aydar first met Fanning's then 15-year-old nephew, Shawn. In All the Rave, Joseph Menn notes that Shawn interned for chess.net in the summer of 1997, sleeping on a couch in the living room. That summer, Aydar and the other chess.net employees became close with the younger Fanning, who was just learning computer programming. Aydar bought Fanning his first book on programming in C++, the language he would use two years later to build the Napster file-sharing software.
Napster
After leaving chess.net, Aydar moved to Chicago, where he worked as a banker. In late 1998, Shawn Fanning contacted Aydar via instant messenger to tell him about a software application he was writing that would enable people to share music. Fanning was then a freshman at Northeastern University. In August 1999, Aydar moved to California's Silicon Valley to work for a startup. Within weeks, he was recruited to join Napster. He joined in September 1999, becoming its first non-founding employee. Initially, Aydar was an individual contributor to Napster's engineering team. Eventually, he moved into a management role as Napster's senior director of technology, where he was responsible for managing the development of Napster's legal service. Aydar authored Napster's search engine software, which supported the millions of search queries Napster users made every day. At that time, Napster was the fastest-growing application in the history of the Internet; at its peak, the service had over 85 million registered users and 2 million simultaneous users around the world. Aydar's server software infrastructure successfully scaled to handle the exponential increase in Napster search queries, helping support Napster's unprecedented growth. Following Napster's shutdown and subsequent bankruptcy, Aydar served as an advisor to the management team of software companyRoxio during its 2003 acquisition of music service Pressplay.
SNOCAP
In June 2003, Aydar joined Shawn Fanning, Jordan Mendelson and Ron Conway at SNOCAP, the digital rights and content management startup Fanning founded after Napster's collapse. A significant number of its employees were people who had worked for Napster; an August 2005 profile in TIME magazine noted that "27% of SNOCAP's employees are Napster veterans." Aydar served as SNOCAP's chief operating officer from the company's inception through its acquisition by imeem in 2008, and for a year also served as its interim CEO. He co-invented SNOCAP's digital registry and MyStore technologies. While at SNOCAP, he also completed an MBA from the Walter A. Haas School of Business at the University of California, Berkeley on a part-time basis.
imeem
Aydar joined imeem as part of its acquisition of SNOCAP in April 2008, and served as the company's chief operating officer. He was an early advisor to imeem, serving on its board of directors from 2003 until 2007. imeem was acquired by MySpace in December 2009.
