Janus Friis ([ˈjɛːnus ˈfʁiˀs]; born 26 June 1976)[1] is a Danish entrepreneur best known for co-founding the file-sharing application Kazaa, and the peer-to-peer telephony application Skype. In September 2005, he and his business partner Niklas Zennström sold Skype to eBay for $2.6B. Friis has maintained ownership interest in Skype through Silver Lake Partners,[2] which sold Skype to Microsoft for $8.5 billion, in May 2011.[3]

At that time, Zennström headed Tele2 in Denmark, and Friis was hired to run its customer support.[7] Friis and Zennström worked together at Tele2 to launch get2net, another Danish ISP, and the portal everyday.com.

After this, the partners decided to leave Tele2. Friis moved into Zennström's small apartment in Amsterdam in January 2000 where they started developing KaZaA,[8] the company responsible for the most popular software for use with the FastTrack file sharing network protocol. Janus Friis and Niklas Zennström developed the FastTrack protocol in 2001.[9]

From the success of KaZaA's peer-to-peer technology the duo co-founded Joltid, a software company developing and marketing peer-to-peer solutions and peer-to-peer traffic optimization technologies to companies.

Friis founded the online music streaming service Rdio with Zennström in 2010. It filed for bankruptcy in November 2015 and announced the sale of assets to Pandora Radio for $75 million.[10]

In 2012, Friis co-founded Wire, a secure collaboration platform that uses end-to-end encryption to protect digital assets.[11]
