Mammoth Holdings
The Firm
Mammoth Holdings was assembled as a car wash roll-up starting in 2018, when the Atlanta private equity firm Red Dog Equity partnered to form the platform. The Pritzker Organization, the investment arm of Tom Pritzker's family, provides equity; CCMP Growth Advisors took a minority stake in December 2022; and Oak Hill Advisors supplies its debt. The company is run from Dallas.
By late 2024 it operated roughly 148 express conveyor washes across eighteen states under more than twenty brand names, calling itself America's premier express car wash platform. It runs a dual growth strategy, developing new greenfield sites while acquiring existing independent and small-chain washes and folding them into its regional banners. Its stated target, the drive to five, is 500 sites.
For a searcher weighing a single express wash or a small local chain, Mammoth is both a competing bidder and the kind of platform a wash eventually sells into. Its recent purchases, from Gloss in suburban Atlanta to Galaxies and Today's in Killeen, Texas, are the owner-operated express tunnels an independent buyer would also be chasing. It concentrates on express conveyor tunnel washes, the format its whole platform is built on.
Read again in September 2026: the newsroom's last post is a November 2024 opening that says the company is actively seeking acquisitions with significant growth capital available. The site has said nothing since, twenty-two months of silence over a homepage that still counts more than 150 locations. The whole archive opened that evening added two Florida washes from the winter of 2022, and the newsroom has been silent since November 2024 while the site is still maintained.
What It Buys
Dallas, Texas. A private-equity-backed express car wash platform of more than 150 conveyor washes in seventeen states, growing by buying independent and small-chain washes and rebranding them under its banners.

Confirmed Deals
5 deals traced to announcements by Mammoth Holdings, 2022 to 2024, newest first. Firms that announce every deal show a fuller run here than firms that report acquisitions as quarterly counts, so read this as the evidence that clears the bar rather than as the firm's whole record.
Nothing newer has cleared the bar in 23 months, against a registry whose newest confirmed deal is September 30, 2026. A gap past 12 months can mean the firm has slowed, or that it has stopped announcing; treat it as a prompt to check its own newsroom before assuming either.
