Crossfader is an iPhone app that makes it incredibly easy for anybody to DJ.
Over one million users around the world have downloaded the app to mix music, and to discover and share amazing "crosses" with others in our global remix community.
We launched Crossfader V4 (Radio) at EDC in Vegas in June, and then began work on Crossfader V5 (Live) which we will start testing next month at ADE in Amsterdam (and which we will launch next March at SXSW along with a beta of our Apple Watch app). Crossfader Live will enable users to broadcast their sets in real-time to other users around the world. Our vision is to create the first on-demand live entertainment utility: a mobile party platform.
We have spent almost two years writing native iOS code that leverages the iPhone's accelerometer, gyroscope and parallax features. There are no libraries for these features and so we have a competitive advantage over anybody else trying to design similar experiences. In addition, we have designed new ways of beat matching and pitch-shifting so that the user can remix virtually any sound on the Internet and still sound good. Our new version of the app will feature our .cfx notation system: short instruction sets are rendered within the app and can be remixed at any time (rather than being streamed homogeneously as .mp3 files).
We are a small group of iPhone developers, DJs and designers based in North Beach, SF. We started working together two years ago and have released four versions of Crossfader, each of which has been featured by Apple in its AppStore. We share a love for electronic music, and for the live experiences within which it flourishes; but we are also hackers and have come together as a team to eliminate the traditional distance between the "professional" performer and "amateur" audience.
Why we're doing this
Whenever we go to a club or festival, we see artists performing music with complex DJ software on their laptops, while their audience are busy using Instagram and other social media apps on their phones. We think it is inevitable that the next generation of live music experiences will feature artists and audiences creating and connecting together with the same mobile software. DJing should be about taste not technique, and Crossfader is the first product that makes this real.
Most impressive accomplishment
In 1995, Seth started Sitespecific, one of the first internet advertising companies, and sold it in 1997. He was the first EIR at Fred Wilson's Flatiron Partners in 2000. He started Majestic Research in 2003 and sold it in 2010 for more than $50mm. In 2011 he helped launch Turntable.fm which Billboard named top music startup of the year.
