VAULT Events is the agency behind KitKatClub on Tour, which takes the party format of Berlin's KitKatClub to other cities. Its current KitKatClub nights run at C2 OST in Karlsruhe and at the Bootshaus in Cologne. The organiser traces its roots to INSOMNIA Events, founded in 1997 by the Berlin promoters Landolf and Dominique to present their Fantasy World parties, among other places at the KitKatClub. It renamed itself VAULT Events in 2011.

The KitKatClub nights are adult parties with fetish and S/M play areas, a protected play area for couples and a strict "Sexual Fantasy" dress code enforced at the door: fetish, latex, leather, costume, drag, burlesque and anything else imaginative and sexy, but no street clothes, jeans or sportswear. Phones are banned throughout. Posted play-area rules ask for consent and safer sex, and a crew wearing badges is on hand at every play area.

The agency also produces events that are not erotic, such as the Bohème Sauvage 1920s parties in Cologne and The Funky Chicken Club, which are not listed here.
