There’s a Maryland corporation called Act Up Enterprises Inc. It was founded in 2011 by Brett Kimberlin “to provide entertainment services to musicians.” So far, it has one artist signed. She’s Tetyana Kimberlin’s elder daughter.
The company doesn’t do much to promote itself or its artist. Here’s its web page.Various websites related to the sole artist affiliated with Act Up refer to it as an artist management company and a record label—an artist management company with no bookings for its client and a label with no releases.
