Founded in 2002, Mammoth Holdings is a holding company that owns multiple car wash brands and operates 22 stores in 2 states. The company washes more than 2 million cars annually. In 2018, Red Dog Equity LLC, in partnership with Tom Pritzker's family business interests (advised by the Pritzker Organization) and management, acquired a controlling interest in Mammoth. With this transaction, Mammoth Holdings has embarked on a different growth strategy in the rapidly changing car wash industry.
