Finneas O'Connell & Sister Billie Part Ways With Best Friends Music
The duo, previously managed by Best Friends Music, transitions to Sandbox Entertainment, a move that could reshape their future projects and industry influence.
Finneas, known for his already massive impact as a producer, songwriter, and artist at a young age, has officially switched management to 
Jason Owen’s Sandbox Entertainment. This marks a notable step for both Finneas and his sister 
Billie Eilish, who rise from their long-time partnership with Best Friends Music co-founders Danny Rukasin and Brandon Goodman.
Under Best Friends, Finneas soared to 21 Grammy nominations and 10 wins, also earning two Oscars alongside Billie for their work on James Bond and Barbie soundtracks. Sandbox, home to country icons like 
Kacey Musgraves and 
Kelsea Ballerini, is now even more open to fresh creative possibilities. Finneas remains a leading force for his generation, continuing to shape modern pop while stepping into new territory with Sandbox.
