About Us
Midstone Service Group is a small, focused Midwest-based group that partners with founder- and family-owned industrial service businesses. We work with companies that play essential roles in keeping facilities safe, compliant, and operating reliably. Unlike traditional private equity, we take a long-term ownership approach—providing patient capital, hands-on operational support, and a permanent home for businesses rooted in the Midwest. We believe the people doing the work should share in the upside, which is why we make employees co-owners through meaningful equity ownership.
Our Services
Midstone Service Group offers owners a flexible partnership backed by long-term group capital, including the option for significant cash upfront at close. We tailor each transaction to fit the goals of the owner—whether that means full liquidity, partial liquidity with rollover equity, or a long-term operating partnership. Our approach preserves local autonomy, protects the legacy you’ve built, and provides the capital, people, and systems needed to support sustainable growth for years to come.
