In 2005, Butler and Caruana co-founded the JB Seed grant program – renamed as The Seed in 2010 – to support artistic expression and encourage the "social, cultural and artistic diversity in Australian society". The couple contributed $80,000 to establish the project. Other supporters include Paul Kelly, Correne Wilkie (Manager, The Cat Empire), Paul and Michelle Gilding (Ecoscorp), Maureen Ritchie, Missy Higgins, John Watson (Eleven Music), John Woodruff (JWM Productions), Sebastian Chase (MGM Distribution), Philip Stevens (Jarrah Records), The Waifs and Blue King Brown.
