Who is behind Mixcloud ?

Mixcloud was created by Nico Perez, Nikhil Shah and Mat Clayton with the intention of building a home for radio presenters and DJs to share and promote their shows without having to use file sharing sites. 

Upon forming the idea, the co-founders teamed up with the ace web developers Sam Cooke and Matt Rawson to build the site using the Django Framework, JQuery, and Flash. For more info see the team page.
