Maratone is a music production company, and started by two music producers and songwriters, Max Martin and Tom Talomaa. Based in Stockholm, Sweden, it was started in January 2001 after the closing of Cheiron Studios. Maratone moved in at Cosmos Studios after the production team Kai Erixon and Kent (Gillström) Isaacs decided to split up after working together for 10 years on numerous productions. Isaacs bought the old Abbey Road/EMI Studios that is now Cosmos Studios. Cosmos Studios is closely affiliated with Cosmos Music Group.
