In 2013, Caillat cofounded Sleeping Giant Music Group, LLC (a Sleeping Giant Media company) with Grammy nominated writer/producer Michael Hodges and writer/producer Kayla Morrison. In 2014, Sleeping Giant partnered with Alcon Entertainment to form ASG Music Group, LLC.

In January 2016, Caillat, who had a passion for the history of the Record Plant studio in Sausalito, California, where Rumours had been recorded, realized the necessity for its restoration. After developing what was thought to be a more sustainable business model for the music industry, he incorporated under the name Marin Music Project at the Record Plant in January 2017.
