From Turntable's "about" page,
Turntable.fm is a social music service made in New York City. The company has a team of about ten people based in NYC, and is backed by VCs like Union Square Ventures and First Round Capital, and angels like Troy Carter, Guy Oseary, Vivi Nevo, Jimmy Fallon, and the Roots.
I did not know this before and thought it was interesting.
