The story
Founded by Vekoma Rides Manufacturing B.V. in 2001.1
Kumbak (originally Kumbak Coasters) was formed on 14 November 2001 just months after the bankruptcy of Vekoma, a roller coaster manufacturer. The company was founded by nine former employees of Vekoma. The company expanded to a total of 16 employees less than a month later. Kumbak's first project was to design a passenger evacuation platform for Great Nor'Easter at Morey's Piers. Since then the company has performed a complete upgrade on several rides originally made by different manufacturers, as well as designing their own water coaster and dark rides.
