In no particular order:
Fighting Gravity
Tape Face
Shin Lim
Siro-A
Spencer Horsman
HORSE
Catapult Entertainment(if anyone remembers them, kudos to you)
Piff the Magic Dragon
Emil and Dariel
And I guess, Stephen Brundage(kind of blanked)
Also sorry about the Season 7 overload, that's when I really started watching
