It was founded in 2002 by singer/songwriter Susan Hyatt (formerly of Pillbox) and guitarist Geoff Tyson (formerly of T-Ride and Snake River Conspiracy).

Joined by drummer Chad Stewart (Faster Pussycat, Gilby Clarke, Motochrist, LA Guns) and bassist Sean Tichenor (formerly of King Black Acid and James Angell), Stimulator's early electronic sound, with its emphasis on 1980s-style new wave keyboards, was reminiscent of the band Garbage.

[1] In 2007, Tyson left the band and the new sound for Stimulator emerged: a mix of classic disco, easy listening California melodies, and Europop.

[7] The band's songs have been licensed to television shows such as NBC's Las Vegas, MTV's The Real World, ABC's Body of Proof, and The Walt Disney Company Film Ella Enchanted.

Stimulator's animated/live action video for "Magic" featured a cameo by singer Cherie Currie from the classic all girl rock group The Runaways.
