Atlantic Street Capital (ASC), a private equity firm that invests in lower middle market companies, has made an additional $70 million investment to further support the operating strategy, member experience, leadership team, and wash quality of its portfolio company, ZIPS Car Wash.

Operating more than 270 locations in 20-plus states over the last 20 years, most of ZIPS’ growth has occurred over the last eight years through strategic acquisition, development, and member growth.

“Express-only car wash chains are a great place to invest yet face challenging consumer trends that need to be addressed by ZIPS and the industry at large,” said ASC managing partner, Andy Wilkins. “This capital is critical for ZIPS’ efforts to think beyond existing industry strategies to accelerate growth, define membership experience, and capture retail attention,”

Atlantic Street initially invested in ZIPS in 2020 and in 2022 increased its investment by acquiring additional equity from founding shareholders through a continuation fund. Since 2020, the company has acquired new locations, substantially upgraded equipment, simplified monthly membership offerings, improved wash quality, and engaged technology to deliver the best consumer experience.
