Mammoth is customer-focused operationally and operator-focused in its approach to acquisitions and seeks to be the partner-of-choice for car wash operators who desire liquidity, growth capital, and a tax-deferred equity opportunity.

Mammoth is the first car wash acquisition platform formed by industry-insiders and is now the 8th largest conveyor car wash operator in the United States according to Commercial Plus's Top 100 list.

In October 2018, Mammoth partnered with Red Dog Equity LLC, an Atlanta-based private equity firm, which, through its partnership with Tom Pritzker's family business interests, provided the equity for the Finish Line acquisition. 

Monroe Capital provided the debt financing. King & Spalding LLP and Alvarez & Marsal Transaction Advisory Group provided Mammoth with legal and accounting services, respectively.
